With a wide input voltage range from 6V to 40V DC (10V to 40V recommended), this buck converter accurately adjusts output voltage and current. Efficiency reaches up to 95% at 24V input to 12V output with 20A load. It features 75V/80A dual MOSFETs for high-current performance. Input and output use high-frequency, low-resistance electrolytic capacitors for low ripple and stable output. Large 30A screw terminals ensure convenient wiring. Two aluminum heat sinks improve thermal dissipation. For optimal performance and safety, reduce power and current when the difference between input and output voltage is large. Input Voltage: 6–40V DC (10–40V recommended) Output Voltage: 1.2–36V DC Output Current: Up to 20A (15A recommended for continuous operation) Efficiency: Up to 95% (24V → 12V @ 20A) Output Ripple: ≤50mV Wiring Method: Screw terminals Short-Circuit Protection: Self-recovering (not intended for prolonged short-circuit conditions) Dimensions: 60 × 53 × 27 mm (2.36 × 2.08 × 1.06 in) Terminal Labels: VO+: Output positive VO−: Output negative +IN: Input positive −IN: Input negative CV: Output voltage adjustment CC: Output current adjustment EN: Enable (low level disables output; high level or floating 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.
