Introduction
This product is the charge and discharge control circuit designed specially for mining lamp,powered by lithium batteries. It adopts linear method and the charge model of constant current and constant voltage in accordance with lithium standard.Its main illuminant discharges in the method of constant current in order to ensure the service life of LED .
Feature
1.One main illuminant and four assistant illuminant,single-source method
2.Red and green double charge indicator lights
3.For lithium battery,plumbic acid battery and lithium iron phosphate battery
4.Optional low-voltage transfer (namely, low voltage switches on the assistant light)
5.Optional main light shunting
