PSU TDSP power supply module
Description
The PSU TDSP power supply module is able to provide power to all modules fitted on a
TDSP rack in order to guarantee correct operations safely and reliably.
In addition to converting the DC or AC voltage into the DC, stabilised voltage required for
correct functioning of the various TDSP modules, the power supply module is fitted with 3
independent phase reference detection channels.
Characteristics / applications
The PSU TDSP power supply module is designed to be fitted on a standard 19” rack and is
set up to allow for multiple use for applications that call for redundancy to guarantee more
reliable working of the protection system. The correctness of the incoming and outgoing
supplies is indicated by 4 LEDs on the panel and 2 relays.
