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°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. 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.
