Description
LM317 Adjustable Power Supply with Switch Rectified Power Regulator Board AC DC Input LM317 Voltage Regulator Circuit
Product Description
This is a DIY kit that requires you to solder each component together. It can input DC/AC power, but can only output DC.
Specification
PCB size
69 x 50 mm
DC input
5-35V
AC input
6-25V
DC output
1.3-30V
Maximum current
1A
Minimum pressure difference
3V
Features
1. Excellent connector. When the main output is connected to the banana jack, two inputs and three outputs (one main output and two auxiliary outputs) make the operation more convenient. 2. Add a transistor to support load protection. Even though the regulated power supply can be adjusted through the LM317T, if the potentiometer is not in good contact, it will burn the load. Then, the transistor can play an important role at this time to support load protection. 3. The size of the heat sink is 30 x 25 x 30mm, which provides enough heat dissipation area for the LM317T. 4. The four corners of the PCB are fixed with studs and nuts to make the installation easier and the placement more stable. 5. Original kit and Class A PCB, thickness 1.2mm. Solder-coated pads make soldering easier.
