What is a Transformer Controller?

The TC-50 and TC-100 Transformer Temperature Controllers monitor up to 3 ventilated Dry-Type transformer windings and 1 ambient temperature. The controllers operate relays by comparing the highest winding temperature to stored set point temperatures and displays 4 thermocouple inputs as well as the stored maximum temperature and its associated winding. The unit provides Fans, Alarm, and Trip output relays. Up to 2 Fans can be controlled.
