Summary
The S 4000/S 5000 series of AC-DC converters represents
a flexible range of power supplies for use in advanced electronic systems. Features include full power factor correction, high efficiency, high reliability, low output voltage noise
and excellent dynamic response to load/line changes.
The converter inputs are protected against surges and transients occurring at the source lines. An input over- and
undervoltage lock-out circuitry disables the outputs if the
input voltage is outside the specified range. Inrush current
limitation is included preventing circuit breakers and fuses
from being damaged at switch-on.
All outputs are overload, open- and short-circuit proof and
are protected against overvoltages by means of a built-in
suppressor diode. The outputs can be inhibited by a logic
signal applied to the connector pin 18 (i). If the inhibit function is not used pin 18 must be connected to pin 14 to enable the outputs.
agencies LGA (Germany) and UL (USA). The UL Mark for
Canada has been officially recognized by regulatory authorities in provinces across Canada.
The case design allows operation at nominal load up to
71°C in a free air ambient temperature. If forced cooling is
provided, the ambient temperature may exceed 71°C but
the case temperature must remain below 95°C under all
conditions.
A temperature sensor generates an inhibit signal which
disables the outputs if the case temperature TC exceeds
the limit. The outputs are automatically re-enabled when
the temperature drops below the limit.
Various options are available to adapt the converters to individual applications.
LED indicators display the status of the converter and allow
visual monitoring of the system at any time.
The modules may either be plugged into 19" rack systems
according to DIN 41494, or be chassis mounted.
Full input to output, input to case, output to case and output
to output isolation is provided. The modules are designed
and built according to the international safety standards
IEC/EN 60950 and have been approved by the safety
Important:
These products are intended to replace the LS 1000 and
LS 2000 in order to comply with IEC/EN 61000-3-2.

The second output of double output units is controlled by
the main output, but has independent current limiting. If the
main output is driven into current limitation, the second output voltage will fall as well and vice versa.
Forward converter (approx. 80 kHz)
Each output is powered by a separate secondary winding
of the main transformer. The resultant voltages are rectified
and their ripples smoothed by a power choke and an output
filter. The control logic senses the main output voltage Uo1
and generates, with respect to the maximum admissible
output currents, the control signal for the primary switching
transistor.
Control circuit
The input voltage is fed via an input fuse, an input filter, a
rectifier and an inrush current limiter to a single transistor
boost converter. This converter provides a sinusoidal input
current (IEC/EN 61000-3-2, class D equipment) and sources a capacitor with a voltage of 360-370 V DC. This capacitor sources a single transistor forward converter.

With double output modules, both outputs loaded with Io nom.
Valid for -7 versions with NTC, (-9 versions exclude the NTC). Initial switch-on cycle. Subsequent switch-on/off cycles increase the inrush current peak value.
AC frequency range 47...63 Hz.
For DC-input please ask your local Power-One partner.
Input Fuse
Reverse Polarity Protection
A fuse mounted inside the converter protects the module
against severe defects. (If operated from a DC-source this
fuse may not fully protect the module when the input voltage exceeds 200 V DC! In applications where the converters operate at source voltages above 200 V DC an external
fuse or a circuit breaker at system level should be installed!)
Should the input voltage to the unit be supplied from a DC
source the built-in bridge rectifier provides reverse polarity
protection. (For DC-input operation, please consult your local Power-One partner.)

Input Under-/Overvoltage Lock-out
If the input voltage remains below approx. 65 V AC or exceeds approx. 280 V AC an internally generated inhibit signal disables the output(s). When checking this function the
absolute maximum input voltage rating U i abs should be
considered! Between Ui min and the undervoltage lock-out
level the output voltage may be below the value defined in
table: Output data (see: Technical Information: Measuring
and Testing).
Inrush Current Limitation
The modules of the versions -7, incorporate an NTC resistor in the input circuitry which – at initial turn on – reduces
the peak inrush current value by a factor of 5...10 to protect
connectors and switching devices from damage. Subsequent switch-on cycles within short periods will cause an
increase of the peak inrush current value due to the warming-up of the NTC resistor. See also: E option.
Inrush Current Peak Value
The inrush current peak value (initial switch-on cycle) can
be determined by following calculation:

is operated at its nominal input voltage and output power,
the temperature measured at the Measuring point of case
temperature TC (see: Mechanical Data) will approach the
indicated value TC max after the warm-up phase. However,
the relationship between TA and TC depends heavily on the
conditions of operation and integration into a system. The
thermal conditions are influenced by input voltage, output
current, airflow and temperature of surrounding components and surfaces. TA max is therefore, contrary to TC max,
an indicative value only.
Single or double output units with equal nominal output voltage can be connected in parallel without any precautions
using option T.
Caution: The installer must ensure that under all operating conditions TC remains within the limits stated in the
table: Temperature specifications.
Notes: Sufficient forced cooling or an additional heat sink
allows TA to be higher than 71°C (e.g. 85°C) if TC max is not
exceeded.
For -7 or -9 units at an ambient temperature TA of 85°C with
only convection cooling, the maximum permissible current
for each output is approx. 40% of its nominal value as per
figure.
With option T (current sharing), all units share the current
approximately equally.
Single output units and/or main and second outputs of double output units can be connected in series with any other
(similar) output.
Note:
– Parallel connection of double output units should always
include both, main and second output to maintain good
regulation of both outputs.
– Not more than 5 units should be connected in parallel.
– Series connection of second outputs without involving
their main outputs should be avoided as regulation may
be poor.
– The maximum output current is limited by the output with
the lowest current limitation if several outputs are connected in series.

Thermal Protection
A temperature sensor generates an internal inhibit signal
which disables the outputs if the case temperature exceeds
TC max. The outputs are automatically re-enabled if the temperature drops below this limit.
It is recommended that continuous operation under simultaneous extreme worst case conditions of the following
three parameters be avoided: Minimum input voltage,
maximum output power and maximum temperature.
Output Protection
Each output is protected against overvoltage which could
occur due to a failure of the control circuit by means of a
voltage suppressor diode which, under worst case conditions, may become a short circuit. The suppressor diodes
are not designed to withstand externally applied overvoltages. Overload at any of the two outputs will cause a
shut-down of both outputs. A red LED indicates the overload condition.

Output Voltage Regulation of Double Output Modules
Output 1 is under normal conditions regulated to Uo1 nom,
independent of the output currents.
Uo2 is dependent upon the load distribution. If both outputs
are loaded with more than 10% of Io nom, the deviation of
Uo2 remains within ±5% of the value of Uo1. The following 3
figures show the regulation with varying load distribution. If
Io1 = Io2 or the two outputs are connected in series, the deviation of Uo2 remains within ±1% of the value of Uo1 provided that a total load of more than 10% of Io nom is applied.
Two outputs of a single S 5000 module connected in parallel will behave like the output of a S 4000 module; the paralleled output is fully regulated. No precautions are necessary in using the R-input and the test sockets.

Note: With open i input: Output is disabled (Uo = off).
(Only for single output units 5.1 V, 12 V, 15 V, 24 V)
The outputs of the module may be enabled or disabled by
means of a logic signal (TTL, CMOS, etc.) applied between
the inhibit input i and the negative pin of output 1 (Vo1–). In
systems with several units, this feature can be used, for example, to control the activation sequence of the converters.
If the inhibit function is not required, connect the inhibit pin
18 to pin 14 to enable the outputs (active low logic, fail
safe). For output response refer to: Hold-up Time and Output Response.
This feature enables for compensation of voltage drops
across the connector contacts and if necessary, across the
load lines. If the sense lines are connected at the load
rather than directly at the connector, the user should ensure
that Uo max (between Vo1+ and Vo1–) is not exceeded. We
recommend connecting the sense lines directly at the female connector.

Programmable Output Voltage (R-Function)
As a standard feature, the modules offer an adjustable output voltage, identified by letter R in the type designation.
The control input R (pin 16) accepts either a control voltage
Uext or a resistor Rext to adjust the desired output voltage.
When not connected, the control input automatically sets
the output voltage to Uo nom.
– If the output voltages are increased above Uo nom via Rinput control, option P setting, remote sensing or option
T, the output current(s) should be reduced accordingly so
that Po nom is not exceeded.
a) Adjustment by means of an external control voltage Uext
between pin 16 (R) and pin 14:
– With double output units the second output follows the
value of the controlled main output. Resistor values as
indicated for the single output units should be used.
The control voltage range is 0...2.75 V DC and allows an
output voltage adjustment in the range of approximately
0...110% Uo nom.

b) Adjustment by means of an external resistor:
Depending upon the value of the required output voltage
the resistor shall be connected
– The R-input (as well as option P) is related to the main
output.
– For correct output voltage adjustment of double output
units the external wiring of the outputs should be according to fig.: R-Function for different output configuration
depending upon the desired output configuration.
– In case of parallel connection the output voltages should
be individually set within a tolerance of 1...2%.

Battery Charging/Temperature Sensor
Test Sockets (Main output only )
The LS are intended for lead acid battery charger applications. For an optimum battery charging and life expectancy
of the battery an external temperature sensor may be connected to the R-input. The sensor is mounted as close as
possible to the battery pole and adjusts the output voltage
of the LS unit according to the temperature of the battery
(which is related to the load of the battery and the ambient
temperature).
Test sockets for measuring the output voltage Uo1 are located at the front of the module. The positive test socket is
protected by a series resistor (see: Functional Description,
block diagrams). The voltage measured at the test sockets
is approximately 30 mV lower than the value measured at
the output terminals.
Depending on the cell voltage and the temperature coefficient of the battery, different sensor types are available.
In case of double output units externally connected in series for Uo = 24 V, 30 V or 48 V the monitored output voltage is 12 V, 15 V or 24 V respectively.
For more information please ask Power-One.

Safety and Installation Instructions
Connector Pin Allocation
Installation Instructions
The connector pin allocation table defines the electrical
potentials and the physical pin positions on the H15 connector. Pin no. 24, the protective earth pin present on all LS
AC-DC converters is leading, ensuring that it makes contact with the female connector first.
The S series AC-DC converters are components, intended
exclusively for inclusion within other equipment by an industrial assembly operation or by professional installers. Installation must strictly follow the national safety regulations
in compliance with the enclosure, mounting, creepage,
clearance, casualty, markings and segregation requirements of the end-use application.
10002
Connection to the system shall be made via the female connector H15 (see: Accessories). Other installation methods
may not meet the safety requirements.
32
The AC-DC converters are provided with pin no. 24 ( ),
which is reliably connected with their case. For safety reasons it is essential to connect this pin with the protective
earth of the supply system.

Edition 01/01.2001
An input fuse is built-in in the connection from pins no. 30
and 32 (P∼) of the unit. Since this fuse is designed to protect the unit in case of an overcurrent and does not necessarily cover all customer needs, an external fuse suitable
for the application and in compliance with the local requirements might be necessary in the wiring to one or both input
potentials, pins nos. 26 and 28 and/or nos. 30 and 32.
Important: Whenever the inhibit function is not in use,
pin no. 18 (i) should be connected to pin no. 14 (S–/Vo1–)
to enable the output(s).
Do not open the modules, or guarantee will be invalidated.
Due to high current values, all LS units provide two internally parallel connected contacts for certain paths (pins 4/6,
8/10, 26/28 and 30/32, respectively). It is recommended to
connect load and supply to both female connector pins of
each path in order to keep the voltage drop across the connector pins to an absolute minimum and to not overstress
the connector contacts if currents are higher than
approx. 8 A. The connector contacts are rated 8 A over the
whole temperature range.
Make sure that there is sufficient air flow available for convection cooling. This should be verified by measuring the
case temperature when the unit is installed and operated in
the end-use application. The maximum specified case temperature TC max shall not be exceeded. See also: Thermal
Considerations.
Check for hazardous voltages before altering any connections.
Ensure that a unit failure (e.g. by an internal short-circuit)
does not result in a hazardous condition. See also: Safety
of operator accessible output circuit.
Cleaning Agents
In order to avoid possible damage, any penetration of
cleaning fluids is to be prevented, since the power supplies
are not hermetically sealed.

Standards and Approvals
All AC-DC converters correspond to class I equipment.
They are UL recognized according to UL 1950, UL recognized for Canada to CAN/CSA C22.2 No. 950-95 and LGA
approved to IEC/EN 60950 standards.
The units have been evaluated for:
• Building in
• Basic insulation between input and case, based on 250 V
AC and 400 V DC
• Double or reinforced insulation between input and output,
based on 250 V AC and 400 V DC
• Basic insulation between output and case based on
200 V AC and DC
• Operational insulation between output and output
• Connecting the input to a primary or secondary circuit
which is subject to a maximum transient rating of 2500 V
(overvoltage category III based on a 110 V primary circuit, overvoltage category II based on a 230 V primary
circuit).
• The use in a pollution degree 2 environment
• The UL 1950 recognition limits the minimum input voltage
to Ui = Ui min + 5 V AC = 90 V AC if the case temperature
exceeds 90°C.
The AC-DC converters are subject to manufacturing surveillance in accordance with the above mentioned UL,
CSA, EN and with ISO 9001 standards.
Isolation
The electric strength test is performed as factory test in accordance with IEC/EN 60950 and UL 1950 and should not
be repeated in the field. Power-One will not honour any
guarantee claims resulting from electric strength field tests.
Important: Testing by applying AC voltages will result in
high and dangerous leakage currents flowing through
the Y-capacitors (see fig.: Block diagram).

10061
Leakage currents flow due to internal leakage capacitance
and RFI suppression Y-capacitors. The current values are
proportional to the mains voltage and nearly proportional to
the mains frequency and are specified at an input voltage of
254 V (50 Hz) where phase, neutral and protective earth
are correctly connected as required for class I equipment.
500 Ω
Under test conditions the leakage current flows through a
measuring instrument (MI) as described in fig.: Measuring
instrument for earth leakage current tests, which takes into
account impedance and sensitivity of a person touching
unearthed accessible parts. The current value is calculated
by dividing the measured voltage by 500 Ω. If inputs of Sunits are connected in parallel, their individual leakage currents are added.

Safety of operator accessible output circuit
If the output circuit of an AC-DC converter is operator accessible, it shall be an SELV circuit according to the IEC/EN
60950 related safety standards.
The following table shows a possible installation configuration, compliance with which causes the output circuit of an
S series AC-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 36 V.
However, it is the sole responsibility of the installer to assure the compliance with the relevant and applicable safety
regulations. More information is given in: Technical Information: Safety.

Option –9 extends the operational ambient temperature

supplies provide full nominal output power with convection
cooling. Option -9 excludes inrush current limitation by
NTC.
The potentiometer provides an output voltage adjustment
range of +10/–60% of Uo nom and is accessible through a
hole in the front cover. This feature enables compensation
for voltage drops across the connector and wiring. Option P
is not recommended if units are connected in parallel.
Option P excludes the R-function. With double output units
both outputs are affected by the potentiometer setting (doubling the voltage setting if the outputs are in series).
If the output voltages are increased above Uo nom via R-input control, option P setting, remote sensing or option T, the
output current(s) should be reduced accordingly so that
Po nom is not exceeded.

T Current Sharing
This option ensures that the output currents are approximately shared between all paralleled modules and increases system reliability. To use this facility, simply interconnect the T pins of all modules and make sure, that
pin 14, the S– pin (S 4000) or the Vo1– pins (S 5000) are
also connected together. The load leads should have equal
length and cross section to ensure equal voltage drops. Not
more than 5 units should be connected in parallel. If output
voltage adjustment is requested we strongly recommend to
use the R-input instead of option P, as with option P the required setting accuracy is difficult to achieve. The output
voltages must be individually set prior to paralleling to
within a tolerance of 1...2% or the R pins should be connected together.

D Undervoltage Monitor
The input and/or output undervoltage monitoring circuit operates independently of the built-in input undervoltage lockout circuit. A logic "low" (JFET output) or "high" signal (NPN
output) is generated at pin 20 as soon as one of the monitored voltages drops below the preselected threshold level
Ut. The return for this signal is Vo1–. The D output recovers
when the monitored voltage(s) exceed(s) Ut + Uh. The
threshold level U ti is adjusted in the factory. The threshold
level U to is either adjusted by a potentiometer, accessible
through a hole in the front cover, or factory adjusted to a
fixed value specified by the customer.
Option D exists in various versions D0...DD as shown in the
following table.

Connector pin D is internally connected via the collectoremitter path of a NPN transistor to the negative potential of
output 1. UD < 0.4 V (logic low) corresponds to a monitored
voltage level (U i and/or Uo1) > U t + U h. The current ID
through the open collector should not exceed 20 mA. The
NPN output is not protected against external overvoltages.
UD should not exceed 40 V.

V ACFAIL Signal (VME)
Available for units with Uo1 = 5.1V
V output (V2, V3):
This option defines an undervoltage monitoring circuit for
the input or input and main output voltage equivalent to option D and generates the ACFAIL signal (V signal) which
conforms to the VME standard.
Connector pin V is internally connected to the open collector of a NPN transistor. The emitter is connected to the
negative potential of output 1. U V ≤ 0.6 V (logic low) corresponds to a monitored voltage level (U i and/or Uo1) <U t.
The current I V through the open collector should not exceed 50 mA. The NPN output is not protected against external overvoltages. U V should not exceed 60 V.
The low state level of the ACFAIL signal is specified at a
sink current of I V ≤ 48 mA to U V ≤ 0.6 V (open-collector output of a NPN transistor). The pull-up resistor feeding the
open-collector output should be placed on the VME back
plane.
After the ACFAIL signal has gone low, the VME standard
requires a hold-up time t h of at least 4 ms before the 5.1 V
output drops to 4.875 V when the output is fully loaded.
This hold-up time t h is provided by the internal input capacitance. See also fig.: Hold-up Time versus Output Power.

Output configuration of options V2 and V3
Option V operates independently of the built-in input undervoltage lock-out circuit. A logic "low" signal is generated at
pin 20 as soon as one of the monitored voltages drops below the preselected threshold level U t. The return for this
signal is Vo1–. The V output recovers when the monitored
voltage(s) exceed(s) U t + U h. The threshold level U ti is adjusted in the factory to 355 V DC. The threshold level U to
either is adjusted during manufacture to a determined customer specified value.

B1 Cooling Plate (see: Mechanical Data)
Where a cooling surface is available, we recommend the
use of a cooling plate (option B1) instead of the standard
heatsink. The mounting system should ensure sufficient
cooling capacity to guarantee that the maximum case temperature TC max is not exceeded. The cooling capacity is calculated by:
(100% – h)
PLoss = –––––––––– (Uo • Io)
h
Efficiency η see: Type survey.
Elongated case for 220 mm rack depth: Option B2.
