With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current. Efficiency can reach up to 96%, measured at 20A when converting 24V to 12V. It features a 75V/80A dual MOSFET design. Equipped with high-frequency, low-resistance electrolytic capacitors on both input and output for low ripple and stable performance. Convenient wiring with 30A screw terminals. The module includes two heat sinks to enhance heat dissipation. When there is a large difference between input and output voltage, please reduce the load 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: ≤50mV Wiring: Terminal block Short Circuit Protection: Auto-recovery (not suitable for prolonged short-circuit operation) Dimensions: 60 x 53 x 27mm / 2.36 x 2.08 x 1.06 inches 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 disables output, high voltage level enables output When input and output share a common ground, CV provides constant voltage output and CC provides constant current output under no-load conditions Color: As shown in image Material: PC + Metal Package Contents: 1 x 300W 20A Step-Down Converter Note: Other accessories not included.
