With a wide input voltage range from 6V to 40V DC, the step-down converter accurately adjusts output voltage and current. Efficiency can reach up to 96%, measured at 20A when converting 24V to 12V. Designed with dual MOSFETs rated at 75V/80A. Features high-frequency, low-resistance electrolytic capacitors on both input and output for low ripple and stable output. Equipped with 30A screw terminals for convenient wiring. Includes two heat sinks to enhance thermal dissipation. When there is a large difference between input and output voltage, reduce load current accordingly. Input Voltage: 6V–40V DC (10V–40V recommended) Output Voltage: 1.2V–36V DC Output Current: Up to 20A (15A recommended) Efficiency: Up to 95% (24V to 12V at 20A) Output Ripple: ≤50mV Wiring Type: Terminal Short Circuit Protection: Auto-recovery (not intended for prolonged short-circuit conditions) Dimensions: 60 × 53 × 27 mm (2.36 × 2.08 × 1.06 in) Terminals: VO+: Output positive VO–: Output negative +IN: Input positive –IN: Input negative CV: Output voltage adjustment CC: Output current adjustment EN: Enable pin — low level disables output; high level enables output When input and output share a common ground, the module operates in constant voltage (CV) mode under no-load conditions and constant current (CC) mode under load.
