Product Description

CE RoHS WS-L***0 solar Intelligent light regulators *2/*4/*8V *0A/*0A/*0A LED light  

WS-L***0 *2/*4V, *0A/ *0A/*0A Street Lamp Controller applies in solar photovoltaic lighing system below ***0W, which coordinates the working of solar panels, batteries and lamps, and is an important module to the whole system. With its virtues of one-tough process, convenient operation, excellent capability and reliable quality, it is a multifunctional and all-purpose solar cotnroller special for various solar street lamps.

WS-L***0 *2/*4V, *0A/ *0A/*0A Solar Street lamp controller is controlled by micro-CPU and intelligently senses outside light. It will automatically turn on lights at dark. This controller also intelligently monitors battery charging and discharging. It will protect batteries by turning off lights automatically when the battery boltage is low. The controllers will floatcharge the batteries by pulse-width-modulation (PWM) automatically as the batteries approach full charge. It will cut off charging current to protest batteries from discharging through the solar panel at dark. The controller also has a protection circuit to prevent accidental damage.

Functions:

1. It can prevent the battery from over-charging and over-discharging.
2. It can prevent reverse charging (the battery charges the solar panel).
3. It can prevent reverse connection of the battery and solar panel.
4. It will start up the lighting system in the evening automatically according to the intensity of the light.
5. It will shut down the lighting system according to the time setting or shut down the lighting system automatically when it is dawn.

Indicator Light:

The controller has a three color battery powerindicator LED light, and a green loadindicator light. They indicator of the working condition of charging and discharging:
