DC-DC 300W 20A Adjustable Voltage Step Down Module

300W 20A DC-DC Stepped Adjustable Constant Current Module provides adjustable output voltage ranges between 1.2V and 36V can be used to. The module provides a wide current output range up to 20 A. For sustained high power output, you need to use a cooling fan on the heatsink.

To increase the stabilization in the output voltage, it has six high-frequency capacitances giving lower output ripple. Dual heatsink design ensures easy and fast heat dissipation.

The module has a built-in 3296 multi-turn potentiometer for high accuracy voltage and current regulation to ensure good stability. Since the voltage and current can be adjusted, it can be used in battery charging, LED driver power supply, vehicle power Supply, etc. It provides ease of use in multiple applications such as.

How to set the module:

When the module output voltage cannot be adjusted (output voltage is always equal to the input voltage) Please adjust the potentiometer counterclockwise until it works 20 turns (20 turns) or more.
For CLOCKWISE INCREASE, Turn COUNTERCLOCKWISE to DECREASE.
When adjusting the potentiometer, please use a multimeter to monitor the voltage.
