Voltage Converter -Buck Constant Current Module Highlights Generic Brand Buck Constant Current Module Description: With a wide input voltage range from 6V to 40V, the buck converter can accurately adjust voltage and current Release. Efficiency can be up to 96% measured at 20A, converting 24V to 12V. It is designed with 75V/80A large current dual MOS tube. The input and output use a high-resistance, low-resistance, low-ripple, stable output electrolytic capacitor. Wiring is convenient with these 30A large current screw terminals. The step-down module has 2 heat sinks which can improve the heat dissipation. If there is a big difference between input and output voltage, please reduce the power and current. specification: 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: 50mV Wiring method: Terminal Short circuit protection: self-recovery (cannot short circuit for a long time) Size: 60 x 53 x 28mm / 2.36 x 2.08 x 1 ,1 inch VO+: positive output VO-: negative output + IN: positive input -IN: negative input CV: output voltage adjustment CC: output current adjustment EN: Enable, low level shutdown output tension; suspension, effective high voltage level When the input and output are grounded, the no-load CV output constant voltage and the DC output constant current Package includes: Adjustable Step-Down Buck Module Constant Converter 1 x 300W 20A Note: Please allow 1-3cm differs due to manual measurement. Due to the different display and different light, the picture may not show the actual color of the item. Thank you for understanding.
