SCR Regulated DC Power Supply Manufacturer,Supplier and Exporter in India
Product Code : JA-PET-1419
The SCR regulated DC power supply trainer is a power electronics board for studying how a phase-controlled SCR bridge produces and regulates a DC output. Students compare inductance-input and capacitor-input filters, open-loop and closed-loop operation, and ramp and pedestal control, measuring output voltage variation, regulation and ripple as the load and line voltage change. It runs on 230 V AC mains (SKU JA-PET-1419).

Experiments on the regulated supply trainer
The listed experiments are:
- Output voltage variation, regulation and ripple in open loop with an inductance input filter, and with a capacitor input filter
- The same measurements in closed loop with shunt-transistor pedestal control, for both filters
- Output voltage for different slopes of a linear resistance-controlled ramp
- Open-loop compensation of line voltage variation
- Closed-loop regulation with a series-transistor controlled ramp in differential amplifier mode
Scope of supply and ordering
The listing covers the power supply trainer with patch cords and operating instructions, supplied by JaincoLab; the multimeter, oscilloscope and variac are separate.
Frequently asked questions
Which filters can be compared on the trainer?
An inductance input filter and a capacitor input filter.
Can the supply be run in closed loop?
Yes. Closed-loop feedback is studied with pedestal and ramp control.
Which instruments are needed?
A 3 3/4 digit multimeter, a 20 MHz dual trace oscilloscope and a 0-230 V, 2 A variac.
