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 when converting 24V to 12V. It is designed with a 75V/80A dual MOSFET configuration. Equipped with high-frequency, low-resistance electrolytic capacitors on input and output for low ripple and stable performance. Features 30A screw terminals for convenient wiring. The module includes two heat sinks to enhance heat dissipation. When there is a large difference between input and output voltage, please reduce the output current. Input Voltage: 6V to 40V DC (10V to 40V recommended) Output Voltage: 1.2V to 36V DC Output Current: 20A maximum, 15A recommended Efficiency: 95% (24V to 12V, 20A) Output Ripple: less than or equal to 50mV Wiring: Terminal block Short Circuit Protection: Auto-recovery type (do not operate in continuous short circuit) 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 function – low voltage level turns off output; open or high voltage level enables output When input and output share a common ground, CV provides constant voltage in no-load condition, CC provides constant current Color: As shown in images Material: PC + Metal Package Contents: 1 x 300W 20A Step-Down Converter Note: Other items not included. Lighting and monitor settings may cause slight variations in color appearance. Measurement error allowed within +/- 1-3cm.
