TSRDF

The TSRDF is a control module, which can be used as a control element of a transformer switching relay when used in combination with external thyristors or semiconductor relays in a three-phase current supply. Using this module transformers can be frequently switched, without Inrush current
peaks. Applying a patented smooth switching procedure the TSRDF module controls the connected solid state control element so that either three-phase transformers and/or three single phase transformers together can be operated with ‘pulse groups’ either in an idle state or loaded condition without inrush current. Using the smooth switching procedure results in the elimination and not only the reduction of inrush current.

Installation

The TSRDF is connected with a solid state controlling element between the mains and the transformer. The required application is selected using DIP-switches.
