DC-DC 20A Step-down Constant Voltage Constant Current Adjustable Car Power Supply Module High Power LED Driver 300W

General descriptionThis DC-DC 20A Step-down Constant Voltage Constant Current Adjustable Car Power Supply Module is designed for high power LED driving applications. It features a wide input voltage range and allows precise adjustments of output voltage and current, making it suitable for various electronic projects.Technical specificationsInput Voltage: 6V to 40V DC (10V to 40V is suggested)Output Voltage: 1.2V to 36V DCOutput Current: 20A (max.), 15A (suggested)Efficiency: 95% (measured at 24V to 12V, 20A)Output Ripple: ≤50mVItem Size: 60 * 53 * 27mm / 2.4 * 2.1 * 1.1inItem Weight: 89g / 3.1ozPackage Weight: 92gPackage Size: 70 * 60 * 30mm / 2.8 * 2.4 * 1.2inWiring InstructionsVO +: Output positiveVO -: Output negative+ IN: Input positive- IN: Input negativeCV: Output voltage regulationCC: Output current regulationEN: Enable, low level to disable output; high voltage level is validUsageWhen both input and output are grounded, the no-load CV output provides constant voltage while the CC output delivers constant current. If there is a significant difference between the input and output voltage, it is recommended to reduce the power and current to prevent damage.Other informationMaterial: FR4Short Circuit Protection: Self-recovery (cannot short circuit for a long time)Heat Dissipation: Equipped with 2 heat sinks for improved thermal managementWiring: Convenient screw terminals rated for large current (30A)
