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 75V/80A large current dual MOS tube. Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output. Wiring is convenient with large current 30A screw terminals. The buck module has 2 heat sinks that enhance heat dissipation. When there is a big difference between input and output voltage, please decrease power and 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 Method: Terminal Short Circuit Protection: Self-recovery (not suitable for prolonged short circuit) 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; high voltage level is effective when suspended When input and output are common grounded, no-load CV output provides constant voltage, CC output provides constant current Color: As shown Material: PC + Metal Package Contents: 1 x 300W 20A Step Down Buck Converter Only the above package content, other products are not included Note: Light shooting and different displays may cause the color of the item in the picture to be slightly different from the real thing. Measurement allowed error is +/- 1-3cm.
