Three Phase Half Full Wave Uncontrolled Rectifier

The Three Phase Half-Full Wave Uncontrolled Rectifier Trainer is designed for practical study of three-phase half-full wave rectification and AC-to-DC conversion. It helps students understand diode rectification, phase-wise operation, and resistive load characteristics through hands-on experiments. The trainer includes an isolated AC supply, digital meters, power diodes, a rheostat load, short-circuit protection, and three-phase indication for clear practical operation. The unit is housed in a metal cabinet with a clearly printed insulated circuit board. Designed and manufactured by Atico Export to meet the practical demands of modern laboratories.
