Single Phase AC Phase Control by Triac

The Single Phase AC Phase Control by Triac is designed for practical study of TRIAC-based AC phase control and gate triggering techniques. It provides a suitable platform for understanding TRIAC operation, phase-angle control, and AC power control through hands-on experimentation. The trainer includes a TRIAC, MOC 2031, and AC phase-control circuit using gate-control firing techniques. Designed and manufactured by Atico Export to meet the practical demands of modern laboratories.
