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% when converting 24V to 12V at 20A. Features a 75V/80A dual MOSFET design. Input and output use high-frequency, low-resistance electrolytic capacitors for low ripple and stable output. Equipped with 30A screw terminals for convenient wiring. Includes two heat sinks to enhance thermal dissipation. When the difference between input and output voltage is large, reduce power and current accordingly. Input Voltage: 6V–40V DC (10V–40V recommended) Output Voltage: 1.2V–36V DC Output Current: Up to 20A (15A recommended) Output Ripple: ≤50mV Wiring Method: Terminal Short Circuit Protection: Self-recovering (prolonged short circuit not recommended) 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.
