DC-DC Adjustable Step Converter Module, 300W 20A Constant Current Voltage Regulator Supply Driver

With a wide input voltage range from 6V to 40V DC (10V to 40V recommended), this step-down converter accurately adjusts output voltage and current. Efficiency reaches up to 95% at 24V input to 12V output with 20A load. It features dual 75V/80A MOSFETs, high-frequency low-resistance electrolytic capacitors on both input and output sides for low ripple and stable output. Wiring is convenient using 30A screw terminals. The module includes two heat sinks for enhanced thermal dissipation. Input Voltage: 6–40V DC (10–40V recommended) Output Voltage: 1.2–36V DC Output Current: Up to 20A (15A recommended) Efficiency: Up to 95% (24V to 12V, 20A) Output Ripple: ≤50mV Short-Circuit Protection: Auto-recovery (not designed 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 enables output) When input and output share a common ground, the unit delivers constant voltage (CV) under no-load conditions and constant current (CC) under load. Color: As shown in image Material: PC + Metal Package Includes: 1 × 300W 20A Step-Down Converter Note: Actual color may vary slightly due to monitor settings and lighting conditions. Dimensional tolerance: ±1–3 mm.
