7.4V 3A Solar Panel Li-ion Battery Charger Controller Regulator PWM

Specifications:

Indicator LED:

LED-State-Function

CHARGE-off-Night condition or the battery not connected

CHARGE-Red light on-state of charge

POWER-off--output protection under state control or light output shutdown

POWER-Green light on-Output Normal

Characteristics of the function:

Working for Li-ion battery's charging control
Voltage: 7.4V
Current: 3A
Working temperature: -30 „ƒ-50„ƒ
Equipped with the MCU, artificially controlled.
Equipped with device to avoid the overcharge, over release, electronic short circuit, over loading, battery inversely connecting, solar battery inversely connecting.
Use the battery discharge rate characteristics to correct discharge control.
The series connection PWM circuit is implemented to form the major charging circuit, make the voltage loss 50% or lower than the diode charging circuit, and the charging efficiency 3%-6% higher than the non-PWM.
The LED displayer shows the batteries current situation to make the customer get the information of the batteries.
Three operatiing modes can be selected: normally open mode, the pure light control mode and light control plus timing mode.

Warnings for usage:

The batteries has stored much energy,please keep the batteries from the short circuit under any circumstances,we strongly recommend connecting the batteries with the fuse.
Please avoid the short circuit wire and the terminal,for the wire and the terminal may generate voltage two times higher than the rated voltage of the controller.Please use the insulated tools while operating the controller.
Ensure the children keep away from the battery and the controller.
Please comply with the manufacturer`s safety advice.

Package Includes:

1 x solar charger controller
