When friends want Variable power supply Switching Regulator Circuit. I thinks this circuit may like friends certainly. It can Adjustable from
0V to 25V at current 10A. By have the prominent point again be the small-sized. Because of use integrated readymade circuit. Decrease the heat has of plentiful follow circuit picture. It uses , IC - L4970 , by use , VR-10K , fine decorate voltage follow want. The LED for show the circuit. A friend should use transformer 10A sizes and are high class ,volt 28VAC and 8VAC with. The capacitors should durable voltage about 50V. Other hardware a friend pleases to see in the circuit yes.
