DC-DC CC CV Buck Converter Board Step Down Power Supply Module 7-32V to 0.8-28V 12A

Features: ? - Fixed turn lamp current is 0.1 times the current value ( Used to identify whether the battery is fully charged When charging). - Made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20?ﾣC to 100?ﾣC constant current 1A, temperature drift less than 1%). Particularly suitable for LED. - High output current, the max output current can reach 8A. - Four high frequency capacitance, can lower output ripple, enhance the work stabilization. - Double heat sink design. MOS schottky diode independent heat sink,which heat dissipation is good,and wona??t affect each other. - Using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever. - 3296 multiturn potentiometer,high accuracy voltage and current regulation, good stability. - Double color lamp, working condition be clear at a glance - Voltage and current are adjustable,wich effect is good. ? Parameters: ? - Module Properties: Non-isolated step-down constant current, constant voltage module (CC CV) charging module - Input Voltage: DC 7-32V - Output Voltage: (1) DC 1.2-28V continuously adjustable.
