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%, tested at 20A with 24V to 12V conversion. Designed with a 75V/80A dual MOSFET configuration. Features high-frequency, low-resistance electrolytic capacitors on input and output for low ripple and stable performance. Equipped with 30A screw terminals for convenient wiring. Includes two heat sinks to enhance heat dissipation. When there is a large difference between input and output voltage, please reduce load current accordingly. 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: Self-recovery type (not designed for prolonged short-circuit operation) Dimensions: 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 level turns off output, high level enables output When input and output share a common ground, CV provides constant voltage under no-load conditions, CC provides constant current Color: As shown in image Material: PC + Metal Package Includes: 1 x 300W 20A Step-Down Converter Note: Other items not included.
