With a wide input voltage range from 6V to 40V, the buck converter can accurately adjust output voltage and current. The efficiency can reach up to 96%, measured at 20A when converting 24V to 12V. It features a 75V/80A large current dual MOSFET. Input and output use high-frequency, low-resistance electrolytic capacitors for low ripple and stable output. Equipped with large current 30A screw terminals for convenient wiring. The buck module includes two heat sinks to enhance heat dissipation. When there is a significant difference between input and output voltage, reduce power and current accordingly. Input Voltage: 6V to 40V DC (10V to 40V recommended) Output Voltage: 1.2V to 36V DC Output Current: 20A (maximum), 15A (recommended) Efficiency: 95% (24V to 12V, 20A) Output Ripple: ≤50mV Wiring Method: Terminal Short Circuit Protection: Self-recovery (not suitable for prolonged short circuits) Dimensions: 60 x 53 x 27mm / 2.36 x 2.08 x 1.06 inches VO+: Output positive VO-: Output negative +IN: Input positive -IN: Input negative CV: Output voltage adjustment CC: Output current adjustment EN: Enable; low voltage level turns off output, high voltage level enables output When input and output share a common ground, CV provides constant voltage under no load, and CC provides constant current.
