3Pcs DC-DC CC CV Buck Converter Board Step Down Power Supply Module 7-32V to 0.8-28V 9A

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
