VO-: Negative output VO+: Positive output Output Voltage: 1.2V to 36V DC Connection Method: Terminal Input Voltage: 6V to 40V DC (10V to 40V recommended) +IN: Positive input Short Circuit Protection: Self-recovery (cannot be short-circuited for a long time) Output Current: 20A (max.), 15A (recommended) EN: Enables output from low voltage level; suspension, high voltage level is effective CV: Output voltage adjustment When input and output are commonly grounded, no load is formed CV constant voltage, CC output constant current Efficiency: 95% (24V to 12V, 20A) Output Ripple: 50mV -IN: Negative input 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 accurately adjust the output voltage and current. Efficiency can be up to 96%, measured at 20A, converting 24V to 12V. It is designed with 75V/80A large current dual MOS tube. Input and output use low resistance, low ripple, stable output high-frequency electrolytic capacitor. Wiring is convenient with these large current screw terminals 30A. The buck module has 2 heatsinks that 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
