Thyristor Time Delay Relay Power Electronic Training Board has 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.

Object:
01. Study of delayed Turn-ON of D.C. load.
02. Study of auto Turn-OFF of D.C. load.
03. Study of delayed Turn-ON of TRIAC as line switch.
04. Study of auto Turn-OFF of TRIAC as line switch.
Features:
The board consists of the following built in parts:
01. 12V D.C. at 2 Amp, Power Supply internally connected.
02. UJT 2N 2646 used as timer.
03. Potentiometer for ramp control to adjust time delay.
04. Set of 3 Capacitors for time delay control.
05. Two SCRs connected in parallel coupled mode.
