1. General
The primary switched mode rectifier type PSS30 (named PSS in the following) delivers an output
power to a maximum of 3.0kW.
Typical applications are DC power supplies, uninterruptable power supplies with parallel connected
batteries. Rectifiers of type PSS have good dynamic regulation properties at input voltage changes
and load variations.
It works with an IV line according to DIN 41772 and is a connection unit, ready for integration in system
cabinets with 19“ standard frame according to DIN 41494. The operation elements, measurement in-
struments and input/output connectors are fitted on the front panel of the module.
Parallel operation of several modules is possible (with or without decoupling diodes at the output side).
In this case the modules operate with decreased line or in current sharing mode (adjustable at factory).
In the current sharing mode the variations of the output currents of the modules are ≤ ±5 % of the
nominal output current.
An internal active decoupling circuit is available as option.
PSS modules also operate single side grounded or ungrounded at input and output.
