Three Phase Controlled Rectifier Manufacturer,Supplier and Exporter in India

Product Code : SCL-EELE-12822

Indian Lab Suppliers supplies the Three Phase Controlled Rectifier (Product ID: 12822) as part of its electronics engineering lab equipment range. It is a trainer for three-phase half-wave, semi-converter and bridge rectifiers with resistive, inductive and motor loads.

Quick Answer

A ramp-comparator firing circuit drives an on-board SCR assembly, and the circuit can be set up as a half-wave rectifier (common-cathode or common-anode), a semi-converter or a bridge. Fixed R, RL and motor loads are fitted, so each configuration can be compared across all three. Sixteen test points show waveforms at the different blocks, and connections follow a printed diagram with 2 mm sockets. The board uses 230 V, 50 Hz for its own ±12 V and +5 V supplies, while the three-phase input comes from an external source; three-phase wiring and the motor load need qualified supervision.
