Description
The Convert Select front end series represents a family of
DIN-rail mountable AC-DC and DC-DC converters with power
factor correction. The converters have been designed
according to the latest industry requirements and standards.
They are ideal for use in outdoor and other demanding
applications to power building control systems, factory
automation, industrial controls, instrumentation, electromagnetic drives, fans, and other DC loads. Different models
are available with a single output or two independently
regulated, electrically isolated outputs with 24, 36, or 48 V.
Special models for battery charging are available.
The outputs deliver an electrically-isolated Safety Extra Low
Voltage, SELV, (except models LXR/LXN1740) and low output
noise. They are no-load, overload, and short-circuit proof. The
electronically controlled short-term peak power capability of up
to 150% of the rated output power enables the front end
converters to deliver additional power to start-up motors or to
safely operate subsequent circuit breakers. Built-in large sized
output capacitors absorb possible reverse energy, which may
be caused by quick deceleration of electromagnetic drives
connected directly to the output. A green LED at the front cover
displays the status of the output(s).
Key features of the Convert Select line include power factor
correction with low harmonic distortion, negligibly low inrush
current, high immunity to transients and surges, and low
electromagnetic emissions. Internal protection circuits such as
input over- and undervoltage lockout, thermal protection, as
well as output overvoltage protection by a second control loop
ensure safe operation of the final system.
The Convert Select Series was designed according to all
relevant international safety standards. The converters are
approved by TÜV and UL, and are UL 508 listed. Adequate
clearances and creepage distances allow operation in pollution
degree 3 environment (with AC input). All board assemblies are
coated with a protective lacquer.

Models with four powertrains have one or two outputs.
Double-output models exhibit individual control of each
output.
The input voltage is fed via fuse, filter, and rectifier to the
powertrains with main transformers designed in planar
technique. The input filter with very small input capacitance
generates virtually no inrush current. An input transient
suppressor protects the converter against high voltage peaks
and surges. Input over- and undervoltage lockout as well as
input current limitation protect the converter from operation
outside of its specification. The input voltage waveform is
sensed by the primary control logic to allow active power
factor correction, forcing the input current to follow the input
voltage waveform.
The secondary side of each main transformer supplies via the
rectifier diode a large electrolytic output storage capacitor
providing for the hold-up time. Double-output models exhibit an
individual control logic for each output. The output voltage and
the output current are measured and fed back to the primary
control logic via an optocoupler. A second control loop monitors
the output voltage. It disables the output in the case of a failure
in the control logic and limits the output voltage.
Built-in temperature sensors monitor the internal temperature of
each powertrain. If the temperature exceeds the limit, the
converter reduces the output power continuously to keep the
temperature below its limit. A green LED on the front cover
confirms the presence of the output voltage(s).
The R input (option R, M1, or M2) allows for external adjustment
of the output voltage by means of a resistor or an external
voltage source. An external sensor can be connected to the R
input and allows for temperature-controlled battery charging;
see Accessories.

Output Power Derating
The output power of LX models must be decreased at low input
voltage and/or powertrain temperature above 125 °C.
The powertrain temperature depends on the output power, the
input voltage, and the cooling method. At low input voltage the
losses increase. At the maximum specified environment
temperature TA free air convection cooling might be
insufficient. As a result, the output power has to be reduced
according to the tables 4 and 5.
An under- and overvoltage lockout protects the converter by
disabling it below Vi min and above Vi max.
The built-in bridge rectifier provides reverse polarity protection
at the input if operated from DC.
Efficiency
η [%]
Note: The measurements have been made at the approval tests
with free air convection cooling according to UL 60950, specified
ambient temperature TA, and with the converter built in a
cardboard box according to UL 508 and a specified temperature
outside the box Tout. The tables give a correlation between TA or
Tout and the case temperature TC (measuring point TC see
Mechanical Data). For models not specified, please contact
Power-One.

A slow blow fuse ( Schurter T 10A, 5 × 20 mm), protected by a
sleeve, is connected in the line input. For DC input voltages
above 250 V an external DC fuse or a circuit breaker must be
installed; observe the Installation Instructions.

Parallel Operation
Double-output models exhibit an independent
control logic each. Both outputs can be
connected in parallel, provided that the options
S (included in M1) and R are not used, since
they influence only the 2nd output. The two pairs
of powertrains share the current due to their
output voltage droop characteristic.
AUX1 10
Vi
Vo+ 6
Vo- 5
Vo- 4
Vo+ 3
Up to 3 converters with the same output voltage
may be operated in parallel. It is possible to
parallel W Series with X Series converters.
Reasonable current sharing is achieved by the
droop characteristic. Correct mode of operation
is highly dependent upon the wiring of the
converters and the impedance of these wires.
Use wires with equal length and equal cross
sections of min. 1.5 mm 2. The best results for
parallel operation can be achieved with the
wiring shown in fig. 6.

Parallel operation of single-output models

The output characteristic, individual for each
group of powertrains, is rectangular with a
droop to ease parallel operation; see fig. 7.
However, a 50% higher output current is
possible for a short time, such allowing start-up
of loads or charging of capacitors; see fig. 8.
Each output is independently protected against
internal overvoltage by means of a second
control loop. When the output voltage exceeds
Vo L, the respective output is disabled.

Caution: The installer must ensure that under all operating
conditions TC remains within the limits stated in the table
Temperature specifications.
Note: Sufficient forced cooling allows TA to be higher than TA max
provided that TC max is not exceeded. It is recommended that
continuous operation under worst case conditions of the
following 3 parameters be avoided: Minimum input voltage,
maximum output power, and maximum temperature.

Any penetration of liquid or foreign solid objects has to be
prevented, since the converters are not hermetically sealed.
Standards and Approvals
2
The X Series converters were approved by TÜV according to
IEC/EN 60950-1:2001, IEC 61010-1:2001/C11, and IEC/EN
50178:1997. The converters are UL508-listed components.
Fig. 16
Cage clamp terminals. Use 0.5 to 2.5 mm 2 (AWG 20 to 12)
solid or stranded wires depending on local requirements.
The converters have been designed in accordance with said
standards for:
• Class I equipment
• Power-supply for building-in, vertical mounting on 35 mm
DIN-rail or on a wall
• Overvoltage category II (III for 110 VAC supply)
The phase input (L) is internally fused; see Input Fuse and
Protection. This fuse is designed to break an overcurrent in
case of a malfunction of the converter and is not customeraccessible.
• Basic insulation between input and case, based on
250 VAC
• Double or reinforced insulation between input and output,
based on 250 VAC and 350 VDC
External fuses in the wiring to one or both input lines (L and/or
N ) may be necessary to ensure compliance with local
requirements. A built-in second fuse in the neutral path is
available as option F.
• Functional insulation between outputs
A second fuse in the wiring to the neutral terminal N or option F
is needed if:
CB Scheme is available (SE-34628).
• Local requirements demand an individual fuse in each
source line
• Neutral and earth impedance is high or undefined
• Functional insulation between outputs and case
• Pollution degree 3 environment (AC-input) and degree 2
(DC input).
The converters are subject to manufacturing surveillance in
accordance with the above mentioned UL standards and with
ISO9001:2000.
• Phase and neutral of the mains are not defined or cannot be
assigned to the corresponding terminals (L to phase and
N to neutral).
See also the Declaration of Conformity (last page).
Models with option F: Caution! Double-pole/neutral fusing.
All X Series converters have been designed by observing the
railway standards EN 50155 and EN 50121. All boards are
coated with a protective lacquer.
If the converter operates at source voltages above 250 VDC,
an external DC fuse or a circuit breaker at system level should
be installed in the phase input line L .
Caution:
• Installation must strictly follow the national safety regulations.
• Do not open this apparatus!

Leakage Currents
Leakage currents flow due to internal leakage capacitance
(mainly the Y-capacitors). The current values are proportional
to the voltage Vi and the frequency fi of the supply (mains). The
leakage currents are specified at maximum operating input
voltage, provided that phase, neutral, and protective earth are
correctly connected as required for class I equipment.
Caution: Leakage current may exceed 3.5 mA, if f i > 63 Hz.
Safety of Operator-Accessible Output Circuits
If the output circuit of a converter is operator-accessible, it shall
be a SELV circuit according to the safety standards IEC/EN
60950.
The converters have SELV output circuits up to an output
voltage of 57.5 V. However, if the isolated outputs are
connected to another voltage source or connected in series
with a total of >57.5 V, the outputs are hazardous.
LED Indicator
A green LED is activated, when the output voltage Vo is within
the normal operating tolerance band.
Note: This LED is also activated, when the converter is not
powered by the input, but a loaded battery is connected to the
output.
Description of Options
Multiple Options M1 or M2
Single options D1, D2, D5, R are available on the AUX1
terminal (10), referenced to Vo– or Vo2–.
The option board is suitable for applications, where several
options are needed. Option M1 is standard for battery charger
models, option M2 is suitable for applications without battery or
for simple applications with battery.
Option M1 and M2 designate a combination of several options
accessible via a D-SUB connector or in some cases on the
AUX1 and AUX2 terminals. Option M1 includes the function S.
Note: In double-output models, the options D1, D5, R, and S
concern only output 2 connected to terminals 6, 7, 8, and 9.
In general, the multiple options M1 or M2 are connected to an
additional D-SUB connector. Some signals (but not option R)
can also be connected to AUX1 and AUX2, if the D-SUB
connector is not suitable to the customer.

In applications without battery-buffering the D1 signal may not
be suitable, since smaller dynamic load changes may cause
D1 to trigger. For such applications, D5 with a trigger level of
approx. 85% of Vo nom should be chosen (e.g., for a bus voltage
of 24.7 V: trigger level at 21 V).

Do not connect GND1 (pin 1) with the neg. output (–)
Do not connect VCC (pin 3) with the positive output (+)
In double-output models, R and S influence output 2 only.
In systems without battery support, D5 signals that Vo (or Vo2 ) is
going to drop below a safe value.
D2: Input Voltage Monitor (Power Fail)
D2 monitors the input voltage V i. When V i drops below 65±3
VAC or 92 VDC, the D2 signal output is high impedance
(open-collector, max. 50 V).
When V i is greater then said level, the signal output D2 is
conducting: VD2 < 1.5 V, I D2 max < 50 mA.

Note: If longer wires are used to connect the R input at the D-SUB
connector, the wiring to pin 1 (GND1) should be done as a star
point connection. If wired differently, the output voltage setting
may be adversely affected.
Sys-OK: Status
This function allows in a battery charger application for
checking, whether the output is correctly following the external
control signal at the R-input (coming for instance from the
temperature sensor). The logic is shown in table 19.
The open-collector output Sys-OK is protected by a Zener
diode and withstands up to 58.6 V. When the system status is
OK, the signal output is low: VSys-OK < 1.5 V, I Sys-OK < 50 mA.
In battery charging systems, an external battery temperature
sensor (see Accessories) can be connected to optimize Vo.
However, adjustment using the R input (pin 2 of D-SUB) is
possible as well. The above shown formulas are valid, but
Vo nom stands for the voltage with open R input (= Vo safe).
Option F: Built-in Second Fuse
R: Adjustment of Vo or Vo2
A built-in second fuse in the neutral line provides safe phaseto-phase connection at low mains voltages (e.g., USA 120 V/
208 V /60 Hz systems).
The R input allows external adjustment of the output voltage in
the range of 50% to 110% Vo nom. Double-output models allow
only adjustment of output 2 (connected to the terminals 6, 7, 8,
and 9). This enables asymmetric output voltage configuration.
The built-in second fuse also enables safe connection to the
mains, where phase and neutral are not defined or cannot be
identified, as e.g., in the case of plug and socket connection to
