5A Constant Current constant voltage buck step down Battery Charging DC-DC Power Module


Product Description
Large current 5A constant current LED driver lithium-ion battery power supply module
5A constant voltage constant current module
When you use this product, the module inputs and outputs to the ground and do not co-together, this will cause the board power current sense resistor is bypassed, so that the module can not adjust the output current size, the case then load easy to burn power chip module.
This module is easy to use, powerful! ! !
A module has three major features to meet most of your occasions! ! !


Module Description:
1. high power, high efficiency, 5A, low ripple;
2. triple:
(1) Use as a normal blood pressure modules with overcurrent protection capability;
(2) as the various voltage lithium batteries, batteries, nickel-cadmium nickel-metal hydride batteries (battery) charger for solar panels, wind turbines and other occasions;
(3) is used as a high-power LED constant current drive module;
3. With constant pressure and constant current modes, there are light indicates which mode is currently in module;
4. When used as a lithium battery charger, you can set the float voltage and the charge current size, there is light indicates is being charged or has been filled;
5. Has the current limit protection, output short circuit even if it will not burn module.
6. This module uses machine placement, reflow soldering, and each module shipments have been two hours before the aging tests to ensure high reliability.
