Power supply module (PSM)
6.1
Application
The power supply module, PSM, with built in binary I/O is used in 1/2 and 3/4 of full width 19”
units. It has four optically isolated binary inputs and five binary outputs, out of which one binary
output is dedicated for internal fail.
6.2
Design
The power supply modules contain a built-in, self-regulated DC/DC converter that provides full
isolation between the terminal and the battery system.
The power supply module, PSM, has four optically isolated binary inputs and four output relays.
