With a wide input voltage range from 6V to 40V DC, the step-down converter accurately adjusts output voltage and current. Efficiency reaches up to 95% at 24V input to 12V output with 20A load. Features dual MOSFETs rated at 75V/80A. Uses 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. Input voltage range: 6V–40V DC (10V–40V recommended). Output voltage range: 1.2V–36V DC. Maximum output current: 20A (15A recommended for continuous operation). Output ripple: ≤50mV. Terminal-type wiring. Short-circuit protection with auto-recovery (not designed 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 (voltage adjustment), CC (current adjustment), EN (enable — 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. Housing material: PC + metal. Package includes: 1 × 300W 20A step-down converter. Note: Color may vary slightly due to lighting and screen settings. Measurement tolerance: ±1–3 cm.
