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.

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.
