Features EXCELLENT PERFORMANCE: With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust the output voltage and current. MAKE YOUR LIFE EASY: Efficiency can be up to 96%, measured at 20A, converting 24V to 12V. Wiring is convenient with these 30A large current screw terminals. THOUGHTFUL DESIGN: It is designed with 75V/80A large current dual MOS tube. The module has 2 heat sinks which could improve heat dissipation. POWERFUL: Input and output use low resistance and high frequency electrolytic capacitor, low ripple, stable output. NOTICE: When there is a large difference between the input and output voltage, decrease the power and current. Specifications: Input voltage: 6V to 40V DC (10V to 40V suggested) Output voltage: 1.2V to 36V DC Output current: 20A (max. ), 15 A (suggested) Efficiency: 95% (24V to 12V, 20A) Output ripple: ≤50mV Wiring method: Terminal Short circuit protection: self-recovery (can not be short circuit for a long time) Size: 60 x 53 x 27mm/2.36 x 2.08 x 1.06 inches. VO + Positive output When input and output have common grounding, output constant voltage CV no load, DC output constant current VO- Negative output + EN Positive Input -EN Enter negative CV Output Voltage Adjustment CC Output Current Adjustment ES Enable, low voltage shutdown output; suspension, high voltage level is effective Package includes: 1 x module.
