300W 20A DC-DC Adjustable Step Down Buck Converter Module, Constant Current Voltage Regulator Power Supply

With a wide input voltage range from 6V to 40V, the step-down converter adjusts output voltage and current. Efficiency reaches up to 96% when measured at 20A, converting 24V to 12V. Designed with 75V/80A large current dual MOS tubes. Input and output utilize high frequency low resistance electrolytic capacitors for low ripple and stable output. Equipped with large current 30A screw terminals. The buck module includes 2 heat sinks for heat dissipation. When there is a significant difference between input and output voltage, decrease power and current. Input Voltage: 6V to 40V DC (10V to 40V recommended) Output Voltage: 1.2V to 36V DC Output Current: 20A (max.), 15A (recommended) Efficiency: 95% (24V to 12V, 20A) Output Ripple: Less than or equal to 50mV Wiring Method: Terminal Short Circuit Protection: Self-recovery (avoid prolonged short circuits) Size: 60 x 53 x 27mm / 2.36 x 2.08 x 1.06 inch 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 shuts off output; unconnected, high voltage level is effective Operation Note: When input and output share a common ground, no-load CV maintains constant voltage, CC maintains constant current Color: As shown Material: PC + Metal Package Contents: 1 x 300W 20A Step Down Buck Converter. Only the listed item is included. Note: Lighting and displays may cause color variations compared to the actual item. Measurement tolerance +/- 1-3cm.
