With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current. Efficiency can reach up to 96%, measured at 20A with 24V to 12V conversion. Designed with a 75V/80A dual MOSFET configuration. Features high-frequency, low-resistance electrolytic capacitors on input and output for low ripple and stable output. Equipped with 30A screw terminals for convenient wiring. Includes two heat sinks to enhance heat dissipation. When there is a large difference between input and output voltage, please reduce output voltage and current accordingly. 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, 20A) Output Ripple: less than or equal to 50mV Wiring: Terminal Short Circuit Protection: Auto-recovery (not suitable for prolonged short circuit) Dimensions: 60 x 53 x 27mm / 2.36 x 2.08 x 1.06 inches 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 shuts off output, high voltage level enables output When input and output share a common ground, CV provides constant voltage output and CC provides constant current output under no-load conditions Color: As shown Material: PC + Metal Package Contents: 1 x 300W 20A Step-Down Converter Note: Light and display differences may cause slight color variation between the image and actual item. Measurement may vary by +/- 1-3cm.
