DC-DC 20A Step-down Constant Voltage Constant Current Adjustable Car Power Supply Module High Power LED Driver 300W Features: This constant current step-down power supply module with a wide input range from 6V to 40V, the step-down converter can precisely adjust the output voltage and current. The maximum efficiency can reach 95%, measured at 20A, converting 24V to 12V. The step-down converter designed with dual MOS tube of large current 75V / 80A. Adopt with high-strength and low-resistance electrolytic capacitor for input and output use, low ripple, stable output. 2 heat sinks mounted on the board, improve the dissipation function for the step dowm module. Wiring is convenient with these screw terminals of large current 30A. If there is a large difference between the input and output voltage, please reduce the power and current. Specifications: Material: FR4 Input Voltage: 6V to 40V DC (10V to 40V is suggested) Output Voltage: 1.2V to 36V DC Output Current: 20A (max.), 15A (suggested) Efficiency: 95% (24V to 12V, 20A) Output Ripple: ≤50mV Wiring Method: Terminal Short Circuit Protection: Self-recovery (cannot short circuit for a long time) Item Size: 60 x 53 x 27mm / 2.4 x 2.1 x 1.1in Item Weight: 89g / 3.1oz Package Weight: 92g Package: 70 x 60 x 30mm / 2.8 x 2.4 x 1.2in Wiring Instructions: VO and: Output positive VO-: Output negative and IN: Input positive - IN: Input negative CV: Output voltage regulation CC: Output current regulation EN: Enable, low level to disable output; pause, high voltage level is valid When both input and output are grounded, the no-load CV output is constant voltage and the CC output is constant current. Package List: 1 x 300W 20A Step-Down Module Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-YJL official store
