It is a well known construction from Electronics Lab. The power supply has a capacity of 0-33V 3A. KD502 power transistors, LM741 operational amplifiers are separately powered. The power supply has automatic switching windings and thermal protection (70 degrees Celsius for power transistors). The fan is controlled by the multimeter, and additionally it has a thermal speed control. Radiators are with Pentium3. Transformer was made on demand – a total of four secondary windings.
And second power supply adapted to 5A current. Transformer without divided winding with capacity of 6A.
