Product Description


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, and 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.


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 a 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 are 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
