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 ( 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°C to 100°C 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 won’ 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.;
