-
Consists of three types of basic firing circuit to trigger SCR
-
Separate sections for R - firing, RC - firing, UJT firing circuit
-
One potentiometer is used to vary the firing angle of UJT firing circuit
-
One potentiometer is used to vary the firing angle of R ,RC- firing circuit
-
1:1 Pulse transformer is used for UJT firing circuit for isolation
-
One no. of SCR with Snubber circuit forms half wave controlled converter circuit
for checking all three firing circuit.
-
Separate inbuilt power supply for R, RC and UJT triggering unit
-
Power ON indication Switch for separate input to power circuit and triggering module.
-
All the important points are terminated with banana connector for monitor/ measure/
study the signals using any one of measuring equipments
