Power supply module (PSM)

Introduction
The power supply module is used to provide the correct internal voltages and full
isolation between the IED and the battery system. An internal fail alarm output is
available.
Alternative connectors of Ring lug or Compression type can be ordered.
Design
There are two types of the power supply module. They are designed for different DC
input voltage ranges see table 633. The power supply module contains a built-in, self-
regulated DC/DC converter that provides full isolation between the terminal and the
external battery system.
The DC input is protected against inverse polarity within the rated DC voltage range.
