With a wide input voltage range from 6V to 40V, this buck-down converter can accurately adjust output voltage and current. Efficiency can reach up to 96%, measured at 20A when converting 24V to 12V. It features a 75V/80A large-current dual MOSFET design. Input and output stages use high-frequency, low-resistance electrolytic capacitors for low ripple and stable output performance. Equipped with 30A screw terminals for convenient and secure wiring. The module includes two heat sinks to enhance heat dissipation. When there is a large difference between input and output voltage, it is recommended to reduce power and current to ensure safe operation. 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 at 20A) Output Ripple: ≤50mV Terminal Wiring: Yes Short Circuit Protection: Self-recovery (not for prolonged short circuits) Dimensions: 60 x 53 x 27mm / 2.36 x 2.08 x 1.06 inches 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 voltage level turns off output, high voltage level enables output When input and output share a common ground, CV mode provides constant voltage output and CC mode provides constant current output under no-load conditions.
