Product Details
Introduction:
It is an AC-DC 110V to 1.25V-12V LM317 Adjustable Step Down Power Supply Buck Voltage Converter LED Display DIY Kit.
It can output stable voltage. Users can change output by operating a potentiometer.
It also can be used as a signal generator or logic circuit or buzzer alarm circuit.
Note:
1.It is a DIY kit so that needs finish install by the user.
2.Its max output power is 2.5W.
3.It can not be used as a charger to charge the phone.
4.Since the output current is not large, it can only supply power to the small current circuit.
5.If the power supply load is too large, the voltage will drop.
Feature:
AC 110V input work voltage
Adjustable output voltage
RC Signal generator
Logic signal test circuit
Buzzer alarm circuit
DIY manual soldering
Simple and easy to operate
