Three Phase Full Wave AC Voltage Controller Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12803
Indian Lab Suppliers supplies the Three Phase Full Wave AC Voltage Controller (Product ID: 12803) as part of its electronics engineering lab equipment range. It studies phase-angle control of a three-phase full-wave AC voltage controller feeding a built-in resistive load.
Quick Answer
In a full-wave controller both half-cycles of each phase are phase-controlled, so the RMS load voltage falls smoothly as the firing angle increases, without the DC component of a half-wave circuit. Three identical firing cards (zero-crossing detector, integrator, comparator and pulse generator), high-frequency gated firing and three pulse-transformer drivers are set by one potentiometer. Power is taken through three 415:50 V, 0.2 A transformers into a built-in three-phase resistive load, and two 3½-digit panel meters read AC voltage up to 300 V. It runs from 415 V AC, 50 Hz three-phase mains with a 0.5 A four-pole MCB. Please confirm the thyristor/diode arrangement of the power stage at quotation. Use an earthed supply and qualified supervision; a 20 MHz dual-trace oscilloscope is needed.
