R Y B Signal Generator with Power Supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12282
Indian Lab Suppliers supplies the R Y B Signal Generator with Power Supply (Product ID: 12282) as part of its electronics engineering lab equipment range. It derives a set of low-voltage three-phase R, Y and B signals from a single-phase 50 Hz input.
Quick Answer
Starting from one 50 Hz sine wave, two IC 741 phase-shifting stages produce two further sinusoids displaced by 120°, so the three outputs form a virtual R Y B three-phase set. Fixed inputs of 3, 5 and 8 V p-p at 50 Hz are available, and an internal ±15 V DC, 50 mA supply powers the op-amps. Students check the amplitudes and the 120° displacement on a dual-trace 20 MHz CRO (not included). The signals are low voltage, which makes three-phase ideas safe to study on the bench.
