Product Features

This product is a 180 KHz fixed frequency PWM buck (step-down) DC/DC module,capable of driving a 5A load with high efficiency, low ripple and excellent line and load regulation.

Parameters:
Input Voltage: DC 4-38V, error ±0.1V
Output Voltage: DC 1.25V to 36V
Output Current: 5A(MAX) It is recommended to use under 4.5A (NOTE: When using high power, add a heat sink to the power supply chip)
Size: 5.4x2.3x1.8CM
Weight: 16g

Fuction:
1.Built in over-temperature protection function
2.Built in current limit function
3.Built in output short-circuit protection function

How to use
1.Access the power supply (4-38V), the power indicator light, the module is working properly.
2.Adjust the blue potentiometer knob (usually clockwise rotation boost, counterclockwise rotationStep-down) and monitor the output voltage with a multimeter to reach the required voltage.
3.A customer reflects the module output voltage can not be adjusted, always equal to the input voltage. When you encounter this problem, please first counterclockwise rotation potentiometer 10 laps above, and then use the module can be normal adjustment of the voltage.
