Simple, low-power, adjustable, linear power supply on the LM317 chip. Super miniature board allows you to place this module in almost any case. The module is equipped with a diode bridge with a filter capacitor, which allows you to connect it directly to the terminals of the transformer with an alternating voltage. Current 1A is provided only with a minimum voltage drop across the stabilizer (adjustment is set to maximum).
Input voltage range: AC 3-25 V
Output voltage range: constant 1.3-30 V
Maximum current: 1 A
