Variable Power Supply 0 to 12 V

Variable Power Supply 0 to 12 V
This Power supply circuit is powered by 12 volt AC power supply rectifier diodes form VD1 ... VD4, included in a bridge circuit and the rectified voltage stabilizer - capacitors CI, C2, zener VD5 and transistors VT1 and VT2. Voltage power supply output from 0 to 12 regulate the variable resistor R2. The highest current given up power supply to the load (300 mA) is limited to permissible direct current rectifier diodes.
