300W 20A Adjustable DC-DC Step-Down Buck Converter Power Supply Module

This 300W 20A Adjustable DC-DC Step-Down Buck Converter Power Supply Module allows you to step down an input voltage of 6V-40V DC and set the output to 1.2V - 36V DC. The output voltage will be lower than the input voltage.
It uses a dedicated benchmark IC and high-precision current sensing resistor. It can also make a more stable constant current and High output current. The max output current can reach 20A. Low output ripple. The high frequency capacitor reduces output ripple. Suitable for LED driver.

We recommend enhanced cooling when operated at an environmental temperature greater than 40C or when the load wattage is greater than 50W. Adding fuses or protection circuit at the input port would be great.

Features:

Wide input voltage range from 6 - 40V, the step-down converter can accurately adjust output voltage and current.

Efficiency up to 96%, measured at 20A, Converting 24V to 12V

It is designed with 75V / 80A current dual MOS tube.

Input and output use high frequency low resistance electrolytic capacitor for stable output.

Large current 30A screw terminals

The buck module has 2 heat sinks for enhanced heat dissipation.

When large input and output voltage occurs, please decrease power and current.
