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.

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.
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.
Page 12 (20) 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).
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.
