Circuit Breaker Using SCR

The Circuit Breaker Using SCR Trainer is designed for practical study of SCR-based circuit breaker operation and protection techniques. It provides a suitable platform for understanding controlled switching, circuit protection, and the operation of resistive loads using SCR circuitry. The trainer includes an isolated AC power supply, diode, SCR, resistive load, capacitors, ICs, and resistors for practical experimentation. The unit is housed in an ABS plastic cabinet with a clearly printed insulated circuit board. Designed and manufactured by Atico Export to meet the practical demands of modern laboratories.
