-65% LM317 Digital Display Adjustable Power Supply Module DC 3V~ 35V (AC 28V) to DC 1.25~32V Voltage Regulator/Driver Power Supply

Ask Question

It is a LM317 Adjustable Power Supply Module, Input Voltage: DC 3V~ 35V or AC0- 28V, Output voltage: DC 1.25~32V can adjust continuously, Output current: 5mA~1.5A, Suitable for Suitable for DIY an adjustable voltage regulated power supply, Industrial equipment Voltage convert, Power Supply Transformers etc.

LM317 is three-terminal adjustable regulator integrated circuit early made by National Semiconductor and widely used in many integrated circuit manufacturers. Easily use , it just need two external resistance to set output voltage. Besides, its linear adjusting ratio and rejection ratio is better than the standard fixed regulators.

  • 1. Adopted two original LM317 big chip in parallel, make the output current increase 1 time, the highest short-circuit current can reach 4.5A.
  • 2. The input part adopts 6A flat bridge to create the bridge rectifier. It can input DC or AC and no need to distinguish between the positive and the negative.
  • 3. The load protection can prevent regulator from ageing and damaged and lead to burn down as suddenly rising voltage.
  • 4. The high precision digital display voltmeter is convenience to view during the process of adjusting voltage, and no need to use additional multimeter to test.
  • 5. Used large volume heat sink which is cooling well, more stable and durable.
  • Input voltage: DC 35V(Max), AC 28V(Max).
