Safety instructions and waste disposal rules
Warning!
Because several components of operating electrical modules are charged by dangerous voltage, the
improper handling of electrical modules may be the cause of accidents involving electrocution, injury,
or material damages.
•Operation and maintenance of electrical modules must be performed by qualified skilled
personnel such as electricians in accordance with EN 50110-1 or IEC 60950.
•Install the module only in areas with limited access to unskilled personnel.
•Before starting work, the electrical module must be disconnected from mains. Make sure that
the module is earthed.
•Do not touch connector pins as they can be charged with dangerous voltage up to 30 seconds
after disconnection.
•Only spare parts approved by the manufacturer must be used.
All electric modules must be disposed of separate from domestic waste at collecting points that
have been set up by the government or municipal authority.
“Separate collection is the precondition to ensure specific treatment and recycling of WEEE and is
necessary to achieve the chosen level of protection of human health and the environment in the
Community.”
The above statement from EU directive 2002/96/EC applies to all electric modules installed within
EU countries.
In countries outside the EU, different rules may apply regarding waste disposal of electric modules.
For more information about waste disposal of your discarded equipment, contact your

1. General
The primary switched mode rectifier type PSS30 (named PSS in the following) delivers an output
power to a maximum of 3.0kW.
Typical applications are DC power supplies, uninterruptable power supplies with parallel connected
batteries. Rectifiers of type PSS have good dynamic regulation properties at input voltage changes
and load variations.
It works with an IV line according to DIN 41772 and is a connection unit, ready for integration in system
cabinets with 19“ standard frame according to DIN 41494. The operation elements, measurement in-
struments and input/output connectors are fitted on the front panel of the module.
Parallel operation of several modules is possible (with or without decoupling diodes at the output side).
In this case the modules operate with decreased line or in current sharing mode (adjustable at factory).
In the current sharing mode the variations of the output currents of the modules are ≤ ±5 % of the
nominal output current.
An internal active decoupling circuit is available as option.
PSS modules also operate single side grounded or ungrounded at input and output.

3. Start up procedure
Before connecting to the input voltage, it should be checked that the voltage information on the type
plate corresponds to the available voltage and also that the polarity corresponds to the connection
plan of the plug. The mains connection is done via a plug at the front side. The protective conductor
should be generally connected (protection class 1, leakage current ≤3.5mA).
Important:
If one pole is grounded at the output side, the module has to be connected with an additional non-fused
earthed conductor wire on the earth screw (left side on front panel). In this case the PE wire should not
be connected to the input connector to prevent earth circuit. This is very important for paralleled mod-
ules without decoupling diodes at the output side.
The DC output and signal contacts are to be connected with a SUB-MIN-D-connector, type 21WA4. For
modules with an output current >40A two heavy-duty contacts are paralleled. In this case it is impor-
tant that both contacts are symmetrically loaded. The current must be ≤40A per each contact. The
signalling contacts for monitoring, sense links and active current sharing mode are also included in the
output connector.
The rectifier has big capacitors at the output. If you connect a switched off module to a battery or
other modules which operates in parallel, a high capacitor charge current will occur. This current can
destroy the contacts on the output connector.
You can avoid this effect considering the following rules:
•Switch on the PSS module before connecting the output plug
•Disconnect the DC bus by switch or fuse
•Charge the capacitors with resistor (approx. 1 Ohm/V)
•Use decoupling diodes at the output side
After switching off, the capacitors are still fully charged. The discharge time is approx. 4s for the input
and approx. 15s for the output side.
The rectifier is forced-cooled with fan. The ambient temperature has to be lower than 45 °C. If more
than one subrack mounting level is used in one cabinet there must be a difference between two
mounting levels of 3U (approx. 130mm) for an unobstructed airflow. The temperature within the cabi-
net should not be higher than 40 °C.
If there is a higher temperature the life time of the modules will be decreased.
The internal losses per module are approx. 260 up to 290W (depending on the type).
4. Operation
All operation elements are fitted on the front panel of the module. The function of each individual
operation element is described on the following pages.
See also section 7. “Operation elements and connectors”.

5.2 Electrical function description
Rectifiers of type PSS consist of following main parts:
1. Line filter to reduce the high-frequency transients produced by the device as well as damping
the transients and noise voltage which are superimposed on the mains.
2. Mains rectifier with switched step-up-converter (operation frequency 100 kHz) to transform the
input voltage in a pre-regulated DC voltage of approx. 380V and to control the waveform of the
input current (sinusoidal!) as well as to control the power factor (>0.99). An additional function
is the limitation of inrush current.
3. Transistor bridge to transform the 380VDC to a pulse width modulated AC voltage with a fre-
quency of 100KHz.
4. HF transformer for the decoupling of the primary and secondary side and adaptation of the volt-
age level to the secondary side.
5. Rectifier diodes
6. LC filter to reduce the voltage ripple at rectifier output.
7. Output filter for RFI suppression and to reduce the noise level on DC line.
8. Internal power supply to supply the primary and secondary control units with potential separa-
tion.
9. Controlled system, opto-decoupled.
10. Adjustment panel for adjustment of output parameters, signals and measurement instruments.
5.2.1 Electrical insulation
Due to the construction principle of the module (module parts) and separated wiring of mains input and
DC output, the PSS meets the following standards:
•Devices with Vo ≤60VDC protection against dangerous body currents through low voltage with
safe electrical decoupling according to EN 60950 and VDE 0100.
•Devices with Vo > 60VDC saved electrical decoupling to Vo = 220VDC according to EN 60950 and
VDE 0160.
5.2.2 Input
The input is protected with a 2-pole circuit breaker. This circuit breaker is also used as on/off-switch.
The MCB is -seen from the mains input side- connected ahead of the input filter. An additional internal
fuse is used to protect the controller.
The rectifier has a current limitation which limits the inrush current to the level of the nominal input
current.
5.2.3 Output
The output line is an IV-line according to DIN 41772 /DIN 41773. Active current sharing mode or de-
creased charge line (-1% at 100% Inom) is possible. Serially the decreased charge line is factory preset.
The output is continuous short circuit proof (constant current controlling).
It is possible to use three different output voltages:
1. Voltage for trickle charge
2. Boost charge
3. Battery test
The output voltage for trickle charge is standard set.
For the use of “Boost charge” or “Battery test”, the pins of the signal connectors are to be connected
as described in section 7.3 “Electrical connectors”.

Eltek Valere Industrial ©2008 UM_PSS30_E_R00
5.2.4 Dynamic regulation of the output voltage
At load jumps between 10 % and 90 % Inom / 90 % and 10 % Inom the dynamic voltage difference is max.
± 3 % and is corrected in max. 1,5 ms to static levels.
5.2.5 RFI suppression
Modules of type PSS meet the standard VDE 0878 T1 and EN 55011/55022 class ‘B’. The output ripple
is (psophometrically measured according to CCITT) < 1mV (24V), < 1,8mV (48V) and <2mV (60V).
5.2.6 CAN-Bus interface
The rectifier PSS is equipped with a serial CAN-Bus interface. Two CAN connectors (RJ11, 6-pole) are
fitted at the front side of the 24V - 110V version. For the 220V version the CAN-Bus connection is inte-
grated in the front side connector X4.
Several modules in a system or parallel connection can be controlled and monitored through the CAN-
Bus by a central DC controller unit MU1000C.
The following parameters of a specific rectifier unit can be controlled or monitored:
•Output voltage
•Output current
•Module status
Furthermore, the rectifier unit receives all threshold values through the CAN-Bus from the
DC controller unit.
REMARK: If several paralleled rectifiers are controlled by a central DC controller unit, it is important to
assign an explicit CAN-Bus address to each individual rectifier (see section 5.4).
5.3 Monitoring
5.3.1 Mains voltage monitoring
Mains voltage monitoring; signalling with LED "Switch symbol", criterion: output voltage of step-up-
converter ≥370 V, at the same time operation monitoring of step-up-converter (equivalent to main
voltage of approx. ≥195 VAC; depends on the load).
The LED is dark if the mains voltage is low or the step-up-converter is out of order.
This signal is included in the collective failure signal of the rectifier. Additional there is an optocoupler
signal (mains O.K.).
For high input voltages (approx. >270VAC) there is implied an automatic switch off function.

User manual
Page 12 (28)
Eltek Valere Industrial ©2008 UM_PSS30_E_R00
5.3.2 Operation monitoring
Functional monitoring; signalling with LED "VO1", criterion: output voltage ≥97 % of adjusted output
voltage without constant current regulation; ≥85 % of adjusted output voltage with constant current
regulation. The signalling threshold of this monitoring automatically follows the adjusted nominal out-
put voltage.
This signal is included in the collective failure signal of the rectifier. Additional there is an optocoupler
signal (Vo O.K.) available.
At operation with internal decoupling diodes the voltage is measured ahead of the diodes.
5.3.3 Monitoring „Boost charge“
If „boost charge“ is activated (see section 6.5), LED V02 is ON, LED V01 is OFF.
5.3.4 Monitoring „Constant current operation“
Constant current operation (output current limiting active) is signalled with a yellow LED I0.
5.3.5 Output voltage low
Output voltage low monitoring; signalling with LED "V<", criterion: Output voltage is higher than ad-
justed level V<; this signal is included in the collective failure signal of the rectifier.
This signal has its own relay contact on the signalling connector. If the voltage value is O.K., pin 13 and
pin 17 of X2 are closed.
5.3.6 Output voltage high
Output voltage high monitoring; signalling with LED "V>", criterion: output voltage higher than adjusted
level V>;
This signal is included in the collective failure signal of the rectifier. If there is an error, the LED is ON
and the rectifier internally switches off. You have to reset the unit by ON/OFF switch.
5.3.7 Protection against overheating/collective failure
A collective failure is signalled with the LED “Bell symbol”. Furthermore overheating is signalled;
criterion: Temperature of the heat sink > 90°C (the unit switches OFF). This signal is included in the
collective failure signal. You have to reset the unit by ON/OFF switch.

5.3.8 Signals
The following signals are available as potential-free optocoupler signals:
1. "Vo O.K.",
2. "Mains O.K."
3. Constant current mode “Iconst"
The maximum contact load is 30V/5mA.
The optocouplers switch OFF at signal 1. and 2., they switch ON at signal 3.
The collective failure signal is delayed for approx. 10s and is available (as well as the signal V>) via a
potential-free relay contact. If a failure exists, the relay switches OFF.
For PSS30, 24/48/60/110V version:
The relay contacts between pin 14 and pin 15 of X2 are open and between pin 15 and pin 16 are closed
at failure.
For PSS30, 220V, only relay version:
The relay contacts between pin 12 and pin 13 of X4 are open and between pin 13 and pin 14 are
closed at failure.
The following monitoring items are included in the collective failure signal:
1. Mains voltage monitoring
2. Operation monitoring
3. Output voltage low
4. Output voltage high
5. Over temperature
5.4 Output and threshold adjustment
The adjustment of output values and monitoring thresholds are very easy. All values are to be adjusted
with front keys; the actual values are indicated with the front side digital displays.
In normal operation the top display shows the output voltage (VO1, VO2 or VO3 depending on the se-
lected operation mode) and the bottom display shows the output current (Io).
In the adjustment mode, the top display shows the name of the parameter, the bottom display shows
the related value.
For any adjustment please follow these instructions:
•press both keys UP/DOWN (↑↓) together for a short time; the rectifier changes to adjustment
mode
•press the key UP (↑) or DOWN (↓) to change the adjustment parameter (see the following table)
•press both keys UP/DOWN (↑↓) together for a short time; the rectifier changes to value change
mode
•press the key UP (↑) or DOWN (↓) to change the adjustment value (if you hold the key the value
changes quicker)
•press both keys UP/DOWN (↑↓) together for a short time; the rectifier changes back to adjustment
mode (at this moment the changed value will be stored)
•press both keys UP/DOWN (↑↓) for approx. 3s. to change to the operation mode
You can leave the adjustment mode at any time with pressing the keys UP/DOWN (↑↓) for approx. 3s.

The threshold values for mains/step-up-converter and over heating are not changeable.
The threshold values of DC voltage low (V<) and DC voltage high (V>) can be individually set within a
limited adjustment range.
For more information regarding the adjustment ranges and factory preset values see section
10. “Technical data”.
6. External Functions
6.1 Output voltage sensor leads
Voltage losses at wires or diodes are to be compensated with sense links for the output voltage.
The maximum regulation difference is approx. 4 % of the nominal voltage.
Cable break at sense links, confusing of poles or short circuit can not damage the rectifier. At cable
break of the sense link, a voltage increase of max. 4% is possible.
6.2 Temperature compensation of the charging voltage
For the use of closed batteries we recommend temperature-controlled compensation of the charge
voltage.
Connect an external active temperature sensor (option) to the signalling connector. The standard set
temperature coefficient is -4mV/K per cell (for a temperature range of 0-50 °C). The basic temperature
is 20°C. The coefficient can be adjusted between 0 to -6mV/K per cell (see section 5.4).
Connect the sensor with a 2-pole wire (0,25mm2). It can be directly mounted on top of the battery or on
battery poles. At great distances (approx. 2m) we recommend the use of a shielded wire with connec-
tion of the shield to rectifiers ground.
6.3 External switch ON/OFF function
The rectifier can be externally switched on/off with applying an external DC voltage over an external
switch to the respective pins according to section 7.3. The output of the PSS rectifier switches OFF, if
the external voltage is applied. In this case, the switch-off does not result in a collective failure signal!
The input is potential free due to the use of an optocoupler and meets the supposition for safe electri-
cal decoupling to mains and output side. The signalling voltage is 10-24V, the internal resistance is
2,7kOhm. The input is protected against reversed polarity. At higher supply voltages the current in the
control circuit has to be limited to approx. 5-7mA with a series resistor (e. g. 6,8kOhm at 48/60VDC).

6.4 Discharge test
It is possible to test the capacity of a battery which operates in parallel with the rectifier.
To select the discharge test mode you have to connect –Vo to pin 2 of the output connector X2 (see
section 7.3).
The discharge test voltage can be adjusted by the user (parameter VO3; see section 5.4).
If the discharge test mode is active, the LED VO1 is ON; LED VO2 is OFF.
6.5 Boost charge mode
The rectifier module has a second charge line (boost charge line). To select this mode you have to
connect +Vo to pin 2 of the output connector X2 (see section 7.3). The boost charge mode is
signalized by LED VO2. The voltage value can be adjusted by the user (see section 5.4).
NOTE: For 60/108/216V units: For the connection to +VOan additional series resistor is to be used
(60 V: 18kOhm; 108 V: 56kOhm; 216V: 150kOhm).

3) At active current sharing mode of paralleled units the pin 8 of each individual module has to be con-
nected.
4) External switch on/off with optocoupler: internal series resistor 2,7kOhm, Imin< = 5mA, Imax = 10mA
(see section 6.3).
NOTE: The input is potential free with safe electrical decoupling to primary side and with 500VDC to
secondary side.
5) The relay outputs are potential free with safe electrical decoupling to primary side and with 500VDC
to secondary side.
ATTENTION! If decoupling diodes are output-side integrated in minus, the use of sense links are not
allowed.
For the 216V version, the DC output and signal connectors are separated.
