Hi,

A laboratory power supply offers an indispensable set for both the professional

and the amateur. This power supply is short-circuit protected and infinitely variable from 0 to 30V

and from 0 to 10A.

Velleman k7200  POWER SUPPLY TECHNICAL DATA


- Output voltage variable from Ov to 30V.

- Fine tuning over 1 V

- Output current limiting device infinitely variable from 0 to 1 OA.

-LED (l ight emitting diode)-indication of current limitation

- Output current: 8A. continuous/1 OA. peak

- Short-cicuit protected

This design had many variants like this one (attached file) this one is a 30vdc 10 amps too.


BUT  if i recall  it doesn't drop all the way to zero volts,  you need to have an -1.2 volts supply added on the voltage potentiometer,  it's inherent to the 723 design
