High current 5A constant current constant voltage step-down module LED drive lithium ion battery charging power module -60766
product detail
When using this product, the input ground and output ground of the module should not be together, which will cause the current sampling resistor on the back of the board to be bypassed, so that the module can not adjust the output current, it is easy to connect the load. Burn the power chip on the module.
Module highlights:
1.High power, high efficiency, 5A, low ripple;
2.triple:
(1) It can be used as a normal buck module with overcurrent protection capability;
(2) It can be used as a charger for various voltage value lithium batteries, batteries, nickel-cadmium nickel-hydrogen batteries (battery packs), for solar panels, wind turbines, etc.;
(3) can be used as a high power LED constant current drive module.
3.There are two modes of constant voltage and constant current, and there are indicators to indicate which mode the module is currently in;
4.When used as a lithium battery charger, you can set the float voltage and charge current, and the indicator light indicates whether it is charging or is full;
5.With current limiting protection, the module will not burn out even if the output is shorted.
