Description: Any electronic part need low voltage DC supply to work and many times we have only AC supply available so we need to convert AC power supply to DC power supply. Converting AC to DC supply can be done by using this simple adjustable power supply module, its based on LM317 that takes power either from center tapped 3 wire transformer or any other DC source and outputs adjustable DC supply. It employs internal current limiting, thermal shutdown, and safe area compensation. Output can be adjusted using the potentiometer.

You would need to use a multimeter to check output first before connecting it with target circuit. Output voltage can be adjustable Between 3 V and 25 V. It can supply maximum of 37 Watt of power with current of 1.5A

Note: In case you want to use transformer with this module then please check you application ampere requirements, if you use a low power transformer then it may get heated quickly.
