Safety Instructions and Waste Disposal Rules
Warning!
Because several components of operating electrical devices are charged by dangerous voltage, the improper han-
dling of electrical devices may be the cause of accidents involving electrocution, injury, or material damages.
•Operation and maintenance of electrical devices 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 device must be disconnected from mains. Make sure that the module is
earthed.
•Do not touch connector pins as they can hold dangerous voltage up to 30 seconds after disconnection.
•Only spare parts approved by the manufacturer must be used.
All electric devices 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 devices installed within EU countries.
In countries outside the EU, different rules may apply regarding waste disposal of electric devices.

3. Start up procedure
Before connecting to the input voltage, it should be checked whether the voltage information on the rating 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 terminals below the cabinet. The protective conductor should be generally connected
(protection class 1, leakage current ≤3.5mA).
The DC output contact has to be connected on terminal X1. The signalling contacts for monitoring, sense links and
active current are to be connected on terminal X2/X3.
Important:
The rectifier has big capacitors at the output. If you connect a switched off module to a battery or other modules
which operate in paralleling, there is a big capacitor charge current. This current may destroy the contacts on out-
put connectors.
WARNING! After switching off, the capacitors hold its voltage for several times. Do not touch!
The rectifier operates with convection cooling. The ambient temperature has to be less than +55°C. If there is a
higher temperature, the life time of the modules will be decreased.
The losses per module are approx. 40 to 80W (depends on type).
4. Operation
All operation elements are located on the front panel of the module. The function of each element is explained on
the following pages. See also the front panel drawing on section 7.1.

5.2 Electrical function description
Rectifiers of type PSR consist of the following main parts:
1. Input filter suppressing the feedback of high frequency interference produced by the unit into the
mains as well as for the attenuation of the interference voltages and voltage transients superim-
posed on the mains.
2. Mains rectifier with switched step-up-converter (operation frequency 100kHz) to transform the
input voltage in a pre-regulated DC voltage of approx. 380V and to control the waveform of input
current (sinusoidal!). An additional function is the limitation of inrush current.
3. Transistor bridge to transform the 380VDC in a pulse width modulated AC voltage with an fre-
quency of 100KHz.
4. HF transformer for decoupling of primary and secondary part and to transport the power to sec-
ondary side.
5. Rectifier diodes to make a DC voltage from high frequency AC voltage.
6. LC-Filter to reduce the voltage ripple on rectifier output.
7. Output filter for RFI suppression and to reduce the noise level on DC line.
8. Internal power supply for supplying of primary and secondary control units with potential decoup-
ling.
9. Regulation line with decoupling through opto couplers.
10. Adjustment panel for adjustment of output parameters, signals and measurement instruments.
5.2.1 Electrical insulation
Through the construction of the module (also module parts) and separate wiring of mains input and DC output the
SMPS fulfils the following standards:
•devices with UO≤60VDC protection against shock current because of low voltage with safe electrical de-
coupling acc. to EN 60950 and VDE 0100.
•devices with UO> 60VDC safe electrical decoupling to UO= 220VDC acc. EN 60950 and VDE 0160.
5.2.2 Input
A one-pole mains switch is used to switch on and off the unit.
The unit is switched on by a run-up stage which limits the switch-on current to <Inom

ELTEK VALERE DEUTSCHLAND ©2009 UM_PSR06-W_E_R1.1
5.2.3 Output
The output line is an IV characteristic acc. to DIN 41772 /DIN 41773 with factory set decreased charge line (-1% at
100% Inom); with factory set active current sharing as option.
The output is sustained short circuit proof (constant current controlling).
5.2.4 Dynamic Regulation of Output Voltage
At load jumps between 10 % and 90 % Inom / 90 % and 10 % Inom the dynamic voltage difference is max. ±3 % and
will be regulated within max. 1.5ms to static levels.
5.2.5 RFI Suppression
Modules of type PSR fulfil the standard VDE 0878 T1 and EN 55011/55022 class ‘B’. The output ripple is (measured
psophometric acc. to CCITT) < 1,2mV (24V),< 1.8mV (48V and 60V).
5.3 Monitoring
5.3.1 Mains Voltage Monitoring
The SMPS is designed for an operation in the specified range (see technical data sheet).
The unit is protected for input voltages up to 270VAC by a varistor at the input-side.
5.3.2 Operation Monitoring
Functional monitoring; signalling with LED "Vout OK", criterion: output voltage ≥97 % of adjusted output voltage
without constant current regulation and ≥85 % of adjusted output voltage with constant current regulation. The
signalling threshold of this monitoring automatically follows the adjusted nominal output voltage.
This signal is included in the collective failure signal of the rectifier. Additional there is an optocoupler signal (VO
O.K.)
At operation with internal decoupling diodes the voltage before diodes will be measured.

ELTEK VALERE DEUTSCHLAND ©2009 UM_PSR06-W_E_R1.1
5.3.3 Output Voltage Low
Output voltage low monitoring; signalling with green LED "Vout>Vmin",
Criterion: output voltage is higher than adjusted level V<;
This signal has its own relay contact on signalling connector. If the voltage value is O.K. Pin 6 and Pin 7 of X2 are
closed.
5.3.4 Output Voltage High
Output voltage high monitoring; signalling with red LED "Vout>",
Criterion: output voltage higher than adjusted level V>;
This signal is included in collective failure signal of rectifier. If there is an error the LED is switched ON and the recti-
fier internally switches OFF. You have to reset the unit by ON/OFF switch.
5.3.5 Protection against Overheating
Protection against overheating; signalling with blinking red LED "Bell symbol", criterion: temperature of heat sink >
90°C. This protection reduces the output power if the temperature is on the limit. This signal is included in collec-
tive failure signal. If the temperature is normally the output power will be increased automatically.
5.3.6 Signals
The signals "VOOK", "Mains OK" and "Constant Current Mode Iconst" are opto coupler signals with a loading of 30
V/5mA. The opto couplers switches off at error. The collective failure signal is delayed for approx. 1sec. The relay
contacts between Pin 3 and Pin 5 of X2 are open and between Pin 4 and Pin 5 are closed at error.

5.4 Output and threshold adjustment
The adjustment of output values and monitoring thresholds are very easy. All values will be adjusted with front
keys by showing the actual value in the front side digital displays. The activation of the 2nd characteristic via an
external circuit is necessary for adjusting the boost charge voltage VO2.
In normal operation the top display shows the output voltage (VO1 and VO2) and the bottom display shows the out-
put current (IO).
For any adjustment please follow the following 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 also table on bottom)
•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 the adjustment
mode (at this moment the changed value will be stored)
•press both keys UP/DOWN (↑↓) for approx. 3 sec. to change back to the operation mode
The adjustment mode is for:
•Adjustment of voltage VO1:
•Normal operation; adjust voltage with potentiometer UO1 to correct value (shown at the top display)
•Adjustment of voltage VO2:
•Switch over the unit to VO2-line by external switch (look chapter 6 for correct connecting of signal connec-
tor); adjust voltage with potentiometer VO2 to correct value (shown at the top display)
•Adjustment of monitoring threshold V<:
•Adjust voltage with potentiometer V< to correct value and measure this value on measurement sockets
U< in front of the unit
•Adjustment of monitoring threshold V>:
•Adjust voltage with potentiometer V> to correct value and
•measure this value on measurement sockets V> in front of the unit
•Adjustment of the current limit Iconst:
•The current limit Iconst is adjusted with the potentiometer Iconst by external load.
The measure value at the measure bushings V> and V< corresponds to V/cell for 2 cells, i.e. there is a voltage of
4.8V at the measure bushing for adjusting the V> to 2.4 V/cell.
The adjustment ranges and the adjustments in the factory should be picked up from the respective technical data
sheet.
Adjustable parameters in adjustment mode:
Display Parameter
Vo1 (=UA1) triple charge voltage
Vo2 (=UA2) boost charge voltage (look also cap. 6.4)
Io (=IA) output current
V< output voltage low threshold (look also cap. 5.3.3)
V> output voltage high threshold (look also cap. 5.3.4)
t coefficient of temperature for temperature
compensation of charge voltage (look also cap. 6.2)
The monitoring thresholds automatically follow the adjusted nominal values of output voltage. The monitoring
thresholds for mains/step-up-converter and over heating are not changeable.
Details about the adjustment ranges of several threshold values, see section “Technical Data”.

6. External Functions
6.1 Output voltage sensor leads
With sense links for output voltage you can compensate voltage losses over wires or diodes.
The max. regulation difference is approx. 4% of nominal voltage. Interruption on sense links, confusing of poles or
short circuit can not damage the rectifier. At interrupt it can be a voltage increase of max. 4%.
6.2 Temperature Compensation of the charging voltage
At using of closed batteries we recommend the temperature controlled compensation of charge voltage.
You have to connect an external active temperature sensor (option) on signalling connector. The coefficient of
temperature is normally -4mV/K per cell (at temperature range of 0-50 °C). The basic temperature is 20°C. The
coefficient can be adjusted between -1 to -6mV/K per cell.
The sensor will be connected with a 2-pole wire (0.25 mm2). It can be mounted directly on top of battery or on bat-
tery poles. At big distances (> 2m) we recommend a shielded wire with connection of the shield on rectifiers
ground.
6.3 External Switch On/Off
The rectifier can be switched on/off with an external signal. The input is free of potential by an opto coupler and
fulfils the supposition for safe electrical decoupling to mains and output side. The signalling voltage is 10-24V, the
internal resistance 2.7kOhm. The input is protected against confusing the poles. At higher supply voltages the
current in the control circuit has to be limited to 5-7mA using a resistor (for instance 6.8 kOhm at 48/60VDC).
6.4 Boost Charge Mode
The rectifier module has a second charge line (boost charge line). To select this mode connect a voltage to pin 1 of
output connector X3 (see cap. 7.3). The voltage value can be adjusted by the user.

8. Maintenance
Due to the implemented components, the SMPS unit virtually is maintenance free. In case of operation in dusty
atmosphere, it is regularly advisable to control the dust inside of the unit and, if necessary, blow it out with com-
pressed air. Deposits of dust can result in reduced cooling and could also result in conductive impurities in combi-
nation with dew formation or high moisture.
