Description
These extremely compact DC-DC converters incorporate all
necessary input and output filters, signaling and protection
features, which are required in the majority of applications.
The converters provide important advantages, such as
flexible output power through primary-side current limitation,
extremely high efficiency, excellent reliability, very low ripple
and RFI noise levels, full input-to-output isolation, negligible
inrush current, soft start, overtemperature protection and
input over- and undervoltage lockout.
The converters are particularly suitable for rugged environments, such as railway applications. They have been de-
Table of Contents
signed in accordance with the European railway standards
EN 50155 and EN 50121-3-2. All printed circuit boards are
coated with a protective lacquer. The converter inputs are
protected against surges and transients occurring on the
source lines and cover a total input voltage range from 16 to
150 VDC with five different types. The outputs are
continuously open- and short-circuit proof.
Full system flexibility and n+1 redundant operating mode are
possible due to series or parallel connection capabilities of
the outputs under the specified conditions. When several
converters (with 3.3 and 5.1 V outputs) are connected in
parallel, the T option allows for a single-wire connection
between the converters to ensure good current sharing.

LEDs at the front panel and an isolated Out-OK signal
(option) indicate the status of the converter. Voltage suppressor diodes and an independent second control loop
protect the outputs against an internally generated overvoltage.
The converters are designed using planar magnetics
transformers and control circuits in hybrid technology. There
are always two powertrains fitted to a converter, each
consisting either of a regulated single output with synchronous rectifier or of a regulated main output with a
tracking second output. The output power may be flexibly
distributed among the main and the tracking output of each
powertrain. Close magnetic coupling in the transformers
and output conductors together with circuit symmetry ensure
tight tracking of the auxiliary output. The switching frequency
is fixed.
As a modular power supply or as part of a distributed power
supply system, the low-profile design significantly reduces
the required volume without sacrificing high reliability. The
converters are particularly suitable for 19" rack systems
occupying 3U/4TE only, but they can also be chassismounted by means of four screws. Connector type is H15 (or
H15S2 for some single-output models). The fully enclosed
black-coated aluminium case acts as heat sink and RFI
shield and protects the converter together with the coating of
all components against environmental impacts.

Output Configuration
The P Series allows high flexibility in output configuration to
cover almost every individual requirement, by simply wiring
outputs in parallel, in series, or in independent configuration, as shown in the following diagrams.
connect converters in parallel without measures to
provide reasonable current sharing. Choose suitable
single-output models, if available.
Note: Unused tracking outputs should be connected parallel to
the respective regulated outputs.
Parallel or serial operation of several converters with equal
output voltage is possible, however it is not advantageous to

minimize the ripple current at the input. They use primary and
secondary control circuits in hybrid technology. The two
converters, called "powertrains" (PT), each generate either a
single output with synchronous rectifier or two isolated
outputs, one fully regulated and the other one tracking (semiregulated), thus providing up to four output voltages. In some
models, both outputs of a powertrain are internally connected in parallel .
The highly efficient input filter together with very low input
capacitance results in very low and short inrush current. After
transformer isolation and rectification the output filter reduces
ripple and noise to a minimum without affecting the dynamic
response. Outputs 3 and 4, if available, are tracking (semiregulated) and rely upon the close magnetic coupling of the
transformer and the output inductor together with the circuit
symmetry for their voltage regulation. A current limitation
circuit is located on the primary side of each powertrain,
limiting the total output current of that powertrain in overload
conditions. This allows flexible power operation of the
outputs from each powertrain. All outputs can either be
connected in series or in parallel; see Electrical Output Data.
An auxiliary converter provides the bias voltages for the
primary and secondary referenced control logic and the
option circuits. An oscillator generates a clock pulse of
307 ±1% kHz, which is fed to the control logic of each
powertrain. The pulsewidth modulation and the magnetic
feedback are provided by special ASICs. The converter is
only enabled, if the input voltage is within the operating
voltage range.
Double-output powertrains are equipped with an independent monitor sensing the output voltage of the tracking
output. It influences the contol logic in order to reduce via the
pulse width the voltages of both outputs. In addition, the
tracking ouputs are protected by a suppressor diode.
Outputs of single-output powertrains are also protected by a
suppressor diode.
The temperature of the heat sink is monitored and causes
the converter to disable the outputs, until the temperature
drops; then the converter automatically resumes.

Input Transient Protection
A VDR (Voltage Dependent Resistor), the input fuse, and a
symmetrical input filter form an effective protection against
input transients, which typically occur in most installations,
but especially in battery-driven mobile applications.
Nominal battery voltages in use are: 24, 36, 48, 60, 72, 96,
and 110 V. In most cases each nominal value is specified in a
tolerance of –30% to +25%, with short excursions to ±40%
or even more.
In some applications, surges according to RIA 12 are
specified in addition to those defined in IEC 60571-1 or EN
50155. The power supply must not switch off during these
surges, and since their energy can practically not be
absorbed, an extremely wide input range is required. The P
Series input range has been designed and tested to meet
these requirements; see Electromagnetic Immunity.
Rext. The whole system is not linear at all and eludes a
simple calculation. One basic condition is given by the
formula:
Vin²
Rext << ——
—•η
Po
Rext is the series resistor of the source voltage including
input lines. If this condition is not fulfilled, the converter
cannot reach stable operating conditions. Worst case
conditions are a low input voltage Vi and a high output power
Po.
Low inductance Lext of the input lines and a parallel
connected input capacitor Cext are helpful. Recommended
values for Cext are given in table 4, which should allow stable
operation up to an input inductance of 2 mH. C i is specified in
table 2.

If the input voltage is below approx. 0.9 Vi min or exceeds
approx. 1.1 Vi max, an internally generated inhibit signal
disables the output(s). However, short extentions specified
in EN 50155 will be withstood without shutdown.

Inrush Current
The inherent inrush current value is lower than specified in
the standard ETS 300132-2 (ver. 3.1). The units operate with
relatively small input capacitance resulting in low inrush
current of short duration. As a result in a power-bus system
the units can be hot plugged-in or disconnected causing
negligible disturbance at the input side.
Input Stability with Long Supply Lines
If a P Series converter is connected to the power source with
long input lines exhibiting a considerable inductance, an
additional external capacitor connected in parallel to the
input improves the stability and avoids oscillations.
Actually, a P Series converter with nominal load acts like a
negative resistor, as the input current rises when the input
voltage decreases. It tends to oscillate with a resonant
frequency determined by the line inductance Lex t and the
input capacitance Ci + Cext and damped by the resistors Ri +

Parallel and Series Connection
The first outputs of power trains with equal nominal output
voltage can be connected in parallel. Where available, we
recommend ordering option T.
Any output can be connected in series with any other output.
If the main and the tracking output of the same power train are
connected in series, consider that the effect of the R-input is
doubled.
• Rated output voltages above 48 V (SELV = Safety Extra Low
Voltage) require additional safety measures in order to comply
with international safety standards.
Parallel operation of two double-output converters with
series-connected outputs is shown in fig. 10. The link
between the T1 pins ensures proper current sharing, even
though only the first outputs are influenced by T1. Sense
lines are connected directly at the connector, and load lines
have equal length and section.
Notes:
• If a tracking output is not used, connect it in parallel to the
respective regulated main output.

• The maximum output current of series-connected outputs is

• Connection of several outputs in parallel should include
measures to approximate all output currents. 3.3 and 5 V
outputs with option T have current-share pins (T or T1), which
must be interconnected. For other outputs, the load lines
should exhibit similar resistance. Parallel connection of
regulated outputs without such precautions is not
recommended.

Output Voltage Regulation
Line and load regulation of the regulated
outputs is so good that input voltage and
output current have virtually no influence to
the output voltage.
Vo1–
Wires of equal length and sectinon
However, if the tracking output is not loaded,
the second control loop may slightly reduce the voltage of the
main output. Thus, unused tracking outputs should be
connected in parallel to the respective main output.
Fig. 11
Redundant configuration
connected after the ORing diodes to maintain the correct
output voltage.
For the 12 V outputs, no current-share feature (option T) is
available. As a result, 2 little diodes Ds (loaded by little
resistors Rs) simulate the voltage drop of the ORing diodes.
Reasonable current sharing is provided by load lines of
equal length and section.
The dynamic load regulation is shown in fig. 12.
Tracking Outputs
Hold-up time
The main outputs 1 and 2 are regulated to Vo nom independent
of the output current. If the loads on outputs 3 and 4 are too
low (<10% of Io nom), their output voltage tends to rise. Vo3 and
Vo4 depend upon the load distribution: If all outputs are
loaded with at least 10% of Io nom, Vo3 and Vo4 remain within
± 5% of Vo nom. The diagrams fig. 13 to 16 show the regulation
of the tracking output under different load conditions up to the
current limit. If Io1 = Io4 and Io2 = Io3 or if the tracking outputs
are connected in series with their respective regulated
outputs, then Vo3 and Vo4 remain within ±1% of Vo nom provided
that the load is at least Io min. A 2nd control loop protects the
tracking outputs against overvoltage by reducing the voltage
of the respective regulated main output.
The converters provide virtually no hold-up time. If a hold-up
time is required, use external output capacitors or input
capacitors of adequate size and decoupling diodes.
Because the P Series converters exhibit main transformers
and main chokes in planar technology, the tracking outputs
follow the main outputs very closely.
Hot Swap
Important: For applications using the hot swap capabilities,
dynamic output voltage changes during plug-in and plug-out
operations may occur.
Formula for additional external input capacitor:
2 • Po • t h • 100
C i ext = ––––––––––––––––––
(V ti2 – Vi min2) • η
Note: If the tracking output (Vo3 or Vo4 is not loaded, it should be
connected in parallel to the respective main output (Vo3 parallel to
Vo2, Vo4 parallel to Vo1).

If a converter is mounted upright in free air, allowing
unrestricted convection cooling, and is operated at its
nominal input voltage and output power at TA max (see table
Temperature specifications), the temperature measured at
the measurement point on the case TC (see Mechanical
Data) will approach TC max after an initial warm-up phase.
However the relationship between TA and TC depends heavily
on the operating conditions and system integration. The
thermal conditions are influenced significantly by the input
voltage, the output current, airflow, and the temperature of the
adjacent elements and surfaces. TA max is therefore contrary
to TC max only an indicative value.
A temperature sensor fitted on the main PCB disables the
output, when the case temperature exceeds TC max. The
converter automatically resumes, when the temperature
drops below this limit. An additional temperature sensor on
each power train reduces the output current limit of that
power train, when the temperature exceeds a safe level.
Output Power at Reduced Temperature
Operating the converters with an output current between Io nom
and Io max requires a reduction in maximum ambient
temperature or forced air cooling in order to keep TC below
95 °C. When TC max is exceeded, the thermal protection is
activated and disables the outputs.
Note: Forced cooling or an additional heat sink can improve the
reliability or allow TA to go beyond TA max, provided that TC max is
not exceeded. In rack systems without proper thermal
management the converters should not be packed too closely
together! In such cases the use of a 5 or 6 TE front panel is
recommended.

Auxiliary Functions
Caution: To prevent damage, Vext should not exceed 20 V, nor be
negative.
Primary Inhibit (Remote On / Off)
Note: If output voltages are set higher than Vo nom, the output
currents should be reduced accordingly, so that the maximum
specified output power is not exceeded.
The inhibit input enables (logic low, pull down) or disables
(logic high, pull up or open-circuit) the output, if a logic signal
(TTL, CMOS) is applied. In systems consisting of several
converters, this feature may be used to control the activation
sequence by logic signals or to enable the power source to
start up, before full load is applied.

Sense Lines
Important: Sense lines should always be connected.
Incorrectly connected sense lines may damage the converter. If
sense pins are left open-circuit, the output voltages are not
accurate.
This feature enables compensation of voltage drop across
the connector contacts and the load lines including ORing
diodes in true redundant systems.
Applying generously dimensioned cross-section load leads
avoids troublesome voltage drop. To minimize noise pick-up,
wire sense lines parallel or twisted to the respective output
line. To be sure, connect the sense lines directly at the
female connector.
The voltage difference between any sense line and its
respective power output pin (as measured on the connector)
should not exceed the following values at nominal output
voltage.

LEDs
The P Series converters exhibit a green LED "In OK",
signaling that the input voltage is within the specified range.
A green LED "Out-OK" indicates for each powertrain that the
respective power train is working correctly, i.e. that its output
control loop is locked. This proves with high probability that
the regulated output exhibit the correct voltage; see also
Option D.
Note: Single-output models exhibit only 1 LED "Out-OK".
2nd Control Loop
The 2nd output voltage of double-output power trains is
watched by an independent monitoring circuit. In the case of
an overvoltage, the primary control logic of the power train is
influenced to reduce the duty cycle, resulting in a lower
voltage on both outputs. Such an overvoltage may occur,
when the 1st output is fully charged and the 2nd output is
nearly unloaded – particularly with dynamic load changes.

• High-current contacts of P1000 models exhibit no restriction of
the output current. Their resistance is only typ. 1 m Ω.
Safety and Installation Instructions
Connector Pin Allocation
The connector pin allocation table defines the electrical
potentials and the physical pin positions on the H15 and
H15S2 connector. Pin no. 26, protective earth, is a leading
pin to ensure that it makes contact with the female connector
first.
30
32
Notes:
• The current through each standard H15 contact depends on
the female connector, the ambient temperature and the air flow
in the region of the connector. We recommend to limit the mean
current to 15 A at 50 °C and to 13 A at 71 °C.
• High currents require a large cross-sectional area of the
connections to the female contacts. We recommend solder or
screw terminal contacts. Each faston connection exhibits a
resistance of typ. 4 m Ω (max. 8 m Ω), which makes it less
suitable for high currents.
• For single-output models with option K, both output contacts
must always be used and connected in parallel to the load with
large cross-sectional area wires or thick copper lands. The
efficiency is lower with option K.

90 – 195 Watt DC-DC Converters
Installation Instructions
These converters are components, intended exclusively for
inclusion within other equipment by an industrial assembly
process or by a professionally competent person. Installation
must strictly follow the national safety regulations in respect
of the enclosure, mounting, creepage distances, clearance,
casualty, markings and segregation requirements of the enduse application.
Connection to the system shall be made via the female
connector H15 or H15S2 (see Accessories). Other installation
methods may not meet the safety requirements. Check for
hazardous voltages before altering any connections. Pin 26
(PE) is a leading pin and is reliably connected to the case. For
safety reasons it is essential to connect this pin to the
protective earth.
The Vi– input (pin 32) is internally fused. This fuse is
designed to protect the converter against overcurrent
caused by a failure, but may not be able to satisfy all
requirements. External fuses in the wiring to one or both
input pins (no. 30 and/or no. 32) may therefore be necessary
to ensure compliance with local requirements.
Important: Whenever the inhibit function is not in use, pin 28 (i)
should be connected to pin 32 (Vi–) to enable the output(s).
Do not open the converters, or the warranty will be
invalidated. Make sure that there is sufficient airflow available
for convection cooling. This should be verified by measuring
the case temperature at the specified measuring point, when
the converter is operated in the end-use application. TC max
should not be exceeded. Ensure that a failure of the converter
does not result in a hazardous condition; see also Safety of
Operator-Accessible Output Circuits.
• Double or reinforced insulation based on 250 VAC or 240
VDC between input and output and between input and
auxiliary circuits
• Overvoltage category II
• Pollution degree 2 environment
• The converters fulfill the requirements of a fire enclosure.
CB-scheme is available (CB 06 07 24238 800).
The converters are subject to manufacturing surveillance in
accordance with the above mentioned UL standards and with
ISO 9001:2000.
Cleaning Agents
The converters are not hermetically sealed. In order to avoid
possible damage, any penetration of liquids shall be avoided.
Protection Degree
The DC-DC converters correspond to protection degree IP
40, provided that the female connector is fitted to the
converter.
Railway Applications
The converters have been designed observing the railway
standards EN 50155:2007 and EN 50121-3-2:2006. All boards
are coated with a protective lacquer.
The P Series converters are certified to the fire protection
class S1 according to DIN 5510-2:2007.
All models with version V114 (or later) are certified to EN
45545. They also comply with NF-F-16, Class I3/F2 (except
when operated in a vertical position, i.e. with the connector
on top or on bottom).
Standards and Approvals
Isolation
The P Series converters are approved according to the safety
standards IEC/EN 60950-1 and UL/CSA 60950-1 2nd Ed.
The electric strength test is performed in the factory as
routine test in accordance with EN 50116 and IEC/EN 60950
and should not be repeated in the field.

Safety of Operator-Accessible Output Circuits
If the output circuit of a DC-DC converter is operator
accessible, it shall be an SELV circuit according to the IEC/
EN 60950 related safety standards.
The following table shows some possible installation
configurations, compliance with which causes the output
circuit of the DC-DC converter to be an SELV circuit
according to IEC/EN 60950 up to a configured output voltage
(sum of nominal voltages if in series or +/– configuration) of
35 V.
However, it is the sole responsibility of the installer to ensure
the compliance with the relevant and applicable safety
regulations.
Use fuses and earth connections as per table below. See also

90 – 195 Watt DC-DC Converters
Description of Options
In redundant systems, the outputs of the converters are
decoupled by ORing diodes. Consequently, a failure of one
converter will not lead to a system failure.
Option D: Out OK Monitor
Option D monitors the state of the output error amplifiers on
both power trains rather than the input voltage, output
voltage, or the current limit. It signals a fault, when one of the
error amplifiers reaches its limit, which means that at least
one output voltage is not within its regulation limits. This
could occur, because the input voltage is below the
minimum level or the load current is too high. This function is
not adjustable.
Since the voltage on the T or T1 pin is referenced to the
sense pin S–, the installer must ensure that the S– pins of all
parallel converters are at the same electrical potential and
that there are no voltage drops across the connection lines
between these pins.
A galvanically isolated open-collector output generates the
“Out OK” signal. The circuit monitors simultaneously that
If the output voltages of parallel connected single-output
converters are programmed to a voltage other than Vo nom by
means of the R pin, the outputs should be adjusted
individually within a tolerance of ±1%.
• the input voltage is present - same logic as LED “In OK”
• the output voltages are within their limits - same logic as
LED(s) “Out OK”.
The open collector is conducting, if the monitored conditions
are fulfilled.
This option is located on a subassembly allowing special
circuit design on customer request.
Vp
Dimensioning of resistor value R p ≥ ––––––
50 mA
Note: Option T is only available for 3.3 V or 5.1 V single-output
power trains and only for output 1.
In double- or triple-output models, option T1 (pin 16) influences
only output 1. Then the R-function is not present, since no pin is
left for that function.
Option B0, B1, B3: Heat Sink
The converter is fitted with an additional heat sink.
Caution: The Out OK circuit is protected by a Zener diode. To
prevent damage, the applied current IOK should be limited to ±50
mA. The Zener diode should not be exposed to more than 0.25 W.

Option T: Active Current Sharing
For 3.3 V and 5.1 V outputs only. The current share facility
should be used, when several converters are operated in
parallel. Examples could be high reliability n+1 redundant
systems or systems providing higher output power.
Using this feature reduces the stress of individual
converters and improves the reliability of the system.
Interconnection of the current-sharing pins T or T1 causes
the converters to share their output currents evenly.
