DC-DC Buck Converter 300W 20A Step Dowm Module Adjustable Voltage 6 40V To 1.2 36V Power Supply Volt Reducer

Features:
This Constant Current Power 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 power and current.

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.
