Thyristor Time Delay Relay

Code: EEB0007

Thyristor Time Delay Relay.Thyristor Time Delay Relay

Power Electronic Training Boardhas been designed specifically to study the operation of SCR and TRIAC triggered by electronic time delay circuit. This facilitates to perform the experiment to students both the modes of operation-delayed turn on and auto turn off to control any type of load i.e. A.C. or D.C. Practical experience on this board carries great educative value for Science and Engineering Students.
