SCR Single Phase Half Controlled Rectifier RC Firing

The SCR Single Phase Half 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, phase control, and the behavior of inductive and resistive loads through hands-on experimentation. The trainer includes an AC phase control firing circuit, SCR, inductive load using a DC motor, and variable resistive load for practical circuit studies. The unit is housed in an ABS plastic cabinet and features a clearly printed insulated circuit board. Designed and manufactured by Atico Export to meet the practical demands of modern laboratories.
