DCDC Buck Converter 300W 20A Step Dowm Module Adjustable

Features:

This Constant Current Supply Volt Reducer Module with a wide range of input from 6V to 40V,the step-down converter can accurately adjust output voltage and current.

The efficiency max can be up to 95%,measured at 20A,converting 24V to 12V.

The buck converter designed with dual MOS tube of large current 75V / 80A.

Adopt with high frequency low resistance electrolytic capacitor for input and output use,low ripple, stable output.

Board mounted 2 heat sink,enhance dissipation function for the step dowm module.

Wiring is convenient with these large current 30A screw terminals. 

When there is a big difference between input and output voltage,please decrease and current.

Item Weight: 89g / 3.1oz  

Package Weight: 92g / 3.2oz 

Package Size: 70*60*30mm / 2.8*2.4*1.2in



Wiring instructions:

VO +: output positive

VO-: output negative

+ IN: Input positive

- IN: Input negative 

CV: Output voltage regulation

CC: Output current regulation

EN: enable,low level to turn off output; pause,high voltage level is valid

When the input and output are grounded,the no-load CV output is constant voltage,and the CC output is constant current.
