DC 300W 20A CC CV Constant Current Adjustable Converter Buck Step-Down Voltage

300W 20A Step down 
Features:
With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current.
The efficiency can be up to 96%, measured at 20A, converting 24V to 12V.
It is designed with 75V/80A large current dual MOS tube.
Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output.
Wiring is convenient with these large current 30A screw terminals.
The buck module has 2 heat sink that could enhance heat dissipation.
When there is a big difference between input and output voltage, please decrease power and current.

Specifications:
Input Voltage: 6V to 40V DC(10V to 40V is suggested)
Output Voltage: 1.2V to 36V DC
Output Current: 20A(max.), 15A(suggested)
Efficiency: 95%(24V to 12V, 20A)
Output Ripple: ≤50mV
Wiring Method: Terminal
Short Circuit Protection: Self-recovery(cannot short circuit for long time)
Size: 60 x 53 x 27mm / 2.36 x 2.08 x 1.06"
VO+: Output positive
VO-: Output negative
+IN: Input positive
-IN: Input negative
CV: Output voltage adjustment
CC: Output current adjustment
EN: Enable, low voltage level shut off output; suspension, high voltage level is effective
When input and output is common grounded, no-load CV output constant voltage,CC output constant current

Package Include:
1 x 300W 20A Constant Current Adjustable Buck Converter Step-Down Voltage Module
