5A Power Supply 1.2V - 25V Adjustable with LM338K

The core of the power supply circuit is LM338K. The circuit diagram 5A power supply with adjustable output voltage from 1.2 to 25V. Construction circuit is compact, all elements except transformer, the printed circuit. Serial element to the cooling body mounted over the aluminum-angular profile. One side of angular profile, therefore, lies between the printed circuit boards and regulators LM338K, the other side is mounted on cooling the body with one flat surface.
