The controller is only applicable to solar power, rated voltage of 12v/24v systems, battery of gel batteries, liquid openings or sealed lead-acid batteries.
Widely used in power generation unmanned, remote mountain villages, wild and domestic. for example, LED lighting, compact lighting systems, emergency lighting, garden lighting, stair lighting, camouflage lights, street lighting, wireless communication, security alarm, border police, traffic warning lights, traffic lights, traffic yellow flashing lights, obstruction lights and so on.
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.
Make the voltage loss half of or lower than the diode charging circuit, and the charging efficiency 3%-6% higher than the non-pwm.
The LED shows the batteries current situation to make the customer get the information of the batteries.
Three operating modes can be selected: normally open mode, the pure light control mode and light control plus timing mode.
Install and method of using:
Firstly, determine the controller output mode, the device factory default setting is normally open mode. If you need to set for the pure light control mode or light control plus timing mode, you need to open the enclosure through set dip switch, changing the discharge mode.
When the key set "on" is 1, the key set "off" is 0, normally open, pure light control.
Connecting the battery first. If correctly connected, battery indicator will light.
Connecting the wire of the solar panel second. If the connection is correct, the indicator light of “charge”will be on or flash 10 seconds later after laying outside under the sun. otherwise, please check the connection, making sure the solar energy panel is laid outdoors under the sunshine.
Connecting the load at the end. If inversely connected, the led lamp may be damaged.
Please pay attention to the anode and the cathode to avoid the inverse connection.
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.
Because of the equipment work may have a fever, please keep ventilation.The device pay attention to water, moisture, in order to avoid damage to the equipment.
