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).
