Power Supply DC variable

This circuit is called a Power Supply DC variable is one of the best advantageous apparatus in the cyberbanking hobbyist’s work. This ambit is not an complete novelty, but a simple, reliable, “rugged” and short-proof, with a capricious voltage up to 24V and capricious so that it is up to 2A.

Capacitor C1 can be 2200 to 6800?F, 35 to 50V. For Q4 charge be army on heatsinks to accumulate a acceptable breeze of acceptable output. For the 2N3055 transistor (Q4) can be replaced with a hardly beneath able TIP3055 type.

Componen used:
P1 = 500R Linear Potentiometer
