VO-: Output negative VO+: Output positive Output voltage: 1.2V to 36V DC Connection method: terminal Input voltage: 6V to 40V DC (10V to 40V suggested) +IN: Input positive Short circuit protection: Self-recovery (cannot short circuit for a long time) Output current: 20A (max.), 15A (suggested) EN: Enable output from low voltage level; suspension, high voltage level is effective CV: Output voltage adjustment When input and output are common ground, no load constitutes CV constant voltage, CC output constant current Efficiency: 95% (24V to 12V, 20A) Output Ripple: 50mV -IN: Input negative CC: Output current adjustment Size: 60 x 53 x 27mm / 2.36 x 2.08 x 1.06" Features: With a wide input voltage range from 6V to 40V, the step-down converter can adjust the output voltage and current precisely. The efficiency can be up to 96%, measured at 20A, and convert 24V to 12V. It is designed with 75V/80A large current with double MOS tube. Input and output use high-frequency electrolytic capacitor with low resistance, low ripple, stable output. Wiring is convenient with these large current screw terminals 30A. The buck module has 2 heat sinks which can improve heat dissipation. When there is a large difference between input and output voltage, please reduce the power and current. Package includes: 1 x 300W 20A Constant Current Adjustable Buck Converter Step-Down Voltage Module
