With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current. The efficiency can be up to 96%, measured at 20A, converting 24V to 12V. It is designed with a 75V/80A current dual MOSFET tube. Input and output high-frequency, low-resistance electrolytic capacitors provide low ripple and stable output. Wiring is convenient with 30A screw terminals. The module has 2 heat sinks to enhance heat dissipation. When there is a large difference between input and output voltage, please reduce the load current. 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: less than or equal to 50mV Wiring: Terminal Short Circuit Protection: Self-recovery (cannot short circuit for long time) Size: 60 x 53 x 27mm / 2.36 x 2.08 x 1.06 inch 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; floating or high voltage level is effective When input and output share a common ground, no-load CV provides constant voltage, CC provides constant current Color: As shown Material: PC + Metal Package Contents: 1 x 300W 20A Step-Down Converter Only the above package content, other products are not included Note: Light and different displays may cause the color of the item to appear slightly different from the real thing. Measurement allows an error of +/- 1-3cm.
