300W 20A DC-DC Buck Converter Step-down Module Constant Current LED Driver Power Step Down Voltage Module Newest Description: Wide input voltage range from 6-40 V, the step-down converter can accurately adjust output voltage and current. Efficiency up to 96%, measured at 20 A, converting 24 V to 12 V It is designed with 75 V / 80 A current dual MOS tube. Input and output use high frequency low resistance electrolytic capacitor for stable output. Large current 30 A screw terminals The buck module has 2 heat sinks for enhanced heat dissipation. When large input and output voltage occurs, please decrease power and current. Specifications: Input voltage: 6 V to 40 V DC(10 V to 40 V suggested) Output voltage: 1.2 V to 36 V DC Output current: 20 A (max.), 15 A (suggested) Efficiency: 95%(24 V to 12 V, 20 A) Output ripple: ≤ 50 mV Wiring method: Terminal Short circuit protection: Self-recovery Size: 60 x 53 x 27 mm / 2.36 x 2.08 x 1.06 in. 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 shut off output; suspension, high voltage level is effective When input and output is common grounded, no-load CV output constant voltage,CC output constant current Package included: 1 Pcs 300W 20A DC-DC Buck Converter Step-down Module
