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
P2 = 10K Log. Potentiometer
R1, R2 = 2K2 1/2W
R3 = 330R 1/4W
R4 = 150R 1/4W
R5 = 1R 5W
C1 = 3300?F 35V
C2 = 1?F 63V
D1, D2 = 1N5402 3A
D3 = 5mm. Red LED
Q1 = BC182
Q2 = BD139
Q3 = BC212
Q4 = 2N3055
T1 = 220V Primary, 36V Center-tapped Secondary
