SCR Single Phase Full Controlled Rectifier RC Firing

The SCR Single Phase Full Controlled Rectifier RC Firing is designed for practical study of SCR-based AC phase control and controlled power conversion. It provides a suitable platform for understanding SCR triggering, RC firing, phase control, and the behavior of inductive and resistive loads through hands-on experimentation. The trainer includes an SCR, RC firing circuit, inductive load using a 12 V DC motor, and variable resistive load for practical circuit studies. Designed and manufactured by Atico Export to meet the practical demands of modern laboratories.
