Product Code : SCL-EELE-12917
Indian Lab Suppliers supplies the Three Phase Half Wave Rectifier with Power Supply (Product ID: 12917) as part of its electronics engineering lab equipment range. It is a three-phase half-wave (three-pulse) diode rectifier with resistive load, used to study phase relations and output waveforms.
Quick Answer
Students first view the three phase voltages from the three-phase transformer and their 120° spacing, then connect the three rectifier diodes to a 600 Ω, 10 W resistive load. Each diode conducts while its phase is the most positive, so the output ripples at three times the supply frequency. Three SPST switches let individual phases be switched in or out, and 3½-digit panel meters read DC output voltage (200 V range) and load current (200 mA range). Mains enters through a 415 V, 20 A three-phase socket, a four-pole MCB and a three-pole contactor with push-to-ON switch, with coloured neon lamps for each phase. The unit works on 415 V three-phase mains: it must be earthed, wired by a qualified person and used under supervision, and waveforms should be viewed with isolated or differential oscilloscope probes rather than a floating oscilloscope.
