Description
DC-DC CC CV Buck Converter Board Step Down Power Supply Module 7-32V to 0.8-28V 12A (10004062)
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, which 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. (2) Fixed output: Choose between 0.8v-28v
