LM317 DIY Kit Step Down Power Supply Module Adjustable Voltage Regulator Switch Resettable Fuse Electrolytic Capacitor Board
This is a DIY kit which needs to weld each component together by yourself.
It can input for DC/AC power,but only can output forDC.
Features:
1.Excellent connectors. Two inputs and three outputs (a main and two auxiliary outputs)
make it more convenient to operate when the main output is connected to the Banana jack.
2.Adding a transistor to support load for protection. Even the regulated power supply can be adjusted by LM317T,
the load will be burned with the poor contact of potentiometer.
Then a transistor can play an important role to support the load for protection at this time.
3.With the dimensions of 30*25*30mm, the heat sink provides LM317T with enough area of dissipation.
4. PCB four corners with studs plus nut fixing, making installation easier, place more stable.
5.Brand new original suite and A level PCB with the thickness of 1.2mm. Pad with solder coating makes the welding much more easier.
