1. 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
ELTEK VALERE DEUTSCHLAND partner.

2. General Information
The PSR327 rectifier rectifies sinusoidal AC input voltage to DC output voltage.
The PSR327 is a hot plug-in module with rear side connectors and is designed to be mounted in an
assembly set 19’’ sub rack (see section 3.2). Due to the state-of-the-art circuitry design, the unit has
very low losses and therefore very compact dimensions, low weight and high power density.
The PSR327 rectifier can be used in all DC applications with or without battery.
The rectifier is delivered with factory set default values for lead acid batteries. If the rectifier is to be
used for NiCd batteries, the default values must be parameterized accordingly using a CAN dongle and
special software.
The nominal output power per unit is 2700 W. Up to a maximum of 48 modules can be switched in
parallel to increase the system output power or to build redundant power supply systems (n + 1-
principle).

3.5 Cooling and Air Flow Direction
The unit is cooled with an internal fan. The airflow is from the front to rear side. The fan is monitored and
speed-controlled dependent on module temperature. To provide sufficient air flow, a minimum space
(see item “A” in figure 5) of 50 mm is required between the unit and the rear cabinet wall as well as an
unobstructed supply of air to the front of the module.
Figure 5) Module air flow
3.6 Communication Interface
The PSR327 rectifier is equipped with a serial data interface in accordance with the Controller Area
Network (CAN) specification. The CAN-Bus connection is integrated in the rear side connector.
Several modules in a system or parallel connection can be controlled and monitored through the CAN-
Bus by a central UPC3 DC controller unit.
The following parameters of a specific rectifier unit can be controlled or monitored:
Output voltage
Output current
Device temperature
Device status
Furthermore, the rectifier unit receives all threshold values through the CAN-Bus from the
DC controller unit.

4. Handling
4.1 Storage
Modules must be stored in a dry, dust free environment with a storage temperature in accordance with
the specific technical data (see section 8).
4.2 Commissioning
Note: Before commissioning the module, make sure that the input voltage corresponds to the input
voltage range of the unit as specified on the type plate and that the output voltage of paralleled units
matches.
1. Carefully unpack the unit
2. Fill the rack beginning with the left slot.
3. Put the unit into an empty slot.
4. Carefully slide in the unit until the module connector touched the backplane connector.
5. Increase the force until the unit fits in completely. Avoid using too much force. If the unit does not
fit in, begin again at step 3.
6. Secure the module using the two captive screws (M3x12) provided with the module.
7. Switch ON the module by external MCB.
Note: The PSR327 is serially equipped with an internal output side decoupling diode. This ensures
hot plug-in capability for the module and enables the operator to add modules under operating
conditions.
Note: Before a module is to be removed, it must be switched off by the external input fuse!
Caution: After switching off the module the internal capacitors are still fully charged. Do not touch
connector pins as they can still be charged with dangerous voltage after disconnection.
4.2.1 Start-up behavior
When the PSR327 is switched on (without CAN-Bus connection) first it provides a start-up voltage
according to the table below. The start-up voltage is held for 60 seconds, than the output voltage steps
up to the internal default value.
PSR327 48V version 60V version 110V version 220V version
Start-up voltage (VDC) 45.0 55.5 97.5 192.0
Default value Vo (VDC) 54.5 68.1 122.6 245.2
If a DC controller unit (UPC3) is integrated into the system, it is powered with the start-up voltage after
the rectifier has been switched on. The output voltage immediately steps up to the value given from the
UPC3 unit via CAN-Bus.
If a DC controller unit (UPC3) is integrated into the system (e.g. powered by the battery and due to this
operating yet) the rectifier directly provides the output voltage given from the UPC3 unit via CAN-Bus.

4.3 Charge Characteristic/Output Power Diagram
The charge characteristic of the PSR327 is a power limited IV characteristic curve in accordance with
DIN 41772/DIN 41773.
For modules in parallel operation mode a load sharing of about ±10% is attained due to a sloping output
voltage line (-1% at 100% Inom).
The module is continuously short circuit proof.
Figure 6) Output power diagram (example PSR327/48-56)
Calculation of the output current (Io) at different output voltage values using the PSR327/48-65 being
the example:
The PSR327 rectifier provides an output power of Vonom x Ionom= Ponom (48V x 56.25A= 2700W).
As shown with the output power diagram (see figure 6), the nominal output current (56.25A) is available
at the nominal output voltage (48.0V).
At other output voltage values (e.g. float or boost charge voltage), the output current is corresponding
to the following formula: Io= Ponom : Vo
Example 1):
Float charge voltage for lead acid batteries (24 cells) = 54.5V; Io= 2700W : 54.5V= 49.5A
Example 2):
Boost charge voltage for lead acid batteries (24 cells) = 57.6V; Io= 2700W : 57.6V= 46.9A

4.6 Threshold & Default Values
The following table shows the factory set threshold/default values internally stored in the PSR327 unit
(for lead acid batteries):
Default values 48V version 60V version 110V version 220V version
Output voltage Vo (VDC) 54.5 68.1 122.6 245.2
Over voltage V> (VDC) 60.0 75.0 135.0 270.0
Current limiting Iconst (ADC) 56.0 45.0 25.0 12.5
Note: The threshold/default values can only be changed in combination with a UPC3 DC controller unit.
If an UPC3 DC controller unit is controlling the power supply unit through the CAN-Bus, the charge
voltage is completely controlled by the UPC3 based on its configuration values and momentary charge
state (for example temperature compensation, boost charge, or battery test). That means that the
values sent from the UPC over CAN-Bus have top priority. During CAN-Bus communication the internally
stored values of the rectifier are invalid.
But when the CAN-Bus connection is inactive for more than five seconds (e. g. due to trouble), the
PSR327 automatically switches back to the internally stored default values. In this case it is ensured
that the battery is charged in the float charge mode.
4.7 Default value setting for NiCd batteries
If the rectifier is to be used to charge NiCd batteries the default/threshold values must be set according
to the individual battery type using a CAN dongle and special software (see section 3.2 “Available
Options and Assembly Equipment”). A specific manual is available on request. For the adjusting range of
the output voltage please see section 8 “Technical Specifications”.

5. External Functions
If the rectifier works together with a UPC3 DC controller unit, the following external functions can be
used:
Compensation of output voltage
Temperature compensation of charge voltage
Discharge test
Boost charge mode
For more information about these functions, read the UPC3 user manual.
6. Maintenance
In general, the rectifier is maintenance-free. Exclusively the fan is a component consisting of moving
parts. By way of precaution a yearly inspection with following checks is recommended:
Mechanical/visual inspection
Removal of dust and dirt, especially on radiator surfaces
Check for internal dust or humidity
It is recommended to exchange the fan every five years.
Attention! Dust combined with moisture or water may influence or destroy the internal electronic
circuits.
Dust inside the unit can be blown out with dry compressed air.
The interval between the checks depends on ambient conditions of the installed module.
