Powerfull Power Supply 12 V/ 10 Ampere

Power supply with 10 A current load

Powerfull power supply 12 Volt / 10 Ampere  requires a safe supply of 220 V, with which you can build and test electronic devices independently assembled, as well as repair of industrial manufacturing device.

Powerfull power supply 12 V/ 10 Ampere Details:
Transistors VT1, VT2 can be replaced with KT808, KT819 with any letter index. It is advisable to use these transistors in a metal case with a diameter of “hats” 23.5 mm. They are mounted on heat sinks with cooling an area of ​​not less than 100 cm2, isolating the heat from the enclosure.

Transistor VT3 can be replaced with KT815, KT817 with any letter index.
transformer T1 standard with an output of at least 100 watts should provide an alternating voltage on the secondary (load) 14-16 V. This voltage is obtained from the findings of the transformer 7 and 16 TH 54-127/220, and there should be a jumper between pins 8-9, 10-11 and 13-14.

The primary winding of the transformer T1 – pins 1 and 2. AKB-standard battery with a rated voltage of 12 V. The relay K1 – for pick-up voltage of 200-220 V with two or more groups of contacts and a current switching at least 3 A Mains fuse FU1 type VI -1-3, PC-30-3 on the current 3 A fuse FU2 at a current of 10 A-type PDK-1-2.

Diode bridge rectifier type KTS405A, KTS407A or assembled from discrete elements – diodes D231, D242 with any letter index. VD6 diode can be replaced by KD202, KD213, KD258 with any letter index and the like.

Zener VD2-VD5 preferably set in accordance with those on the  Powerfull power supply 12 V/ 10 Ampere scheme. Depends on their parameters and the stabilization of output voltage. Capacitors CI, C2-type K40-U9, K10-17 or equivalent, calculated on the operating voltage of at least 250 V. Oxide Capacitors K50-type ST, K50-24 or similar.

Fixed resistors R2, R3-type MLT-0, 5. Resistors Rl, R4-type SEW-10 Exp-S.


Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
