1.Product Introduction
The maximum conversion efficiency of the automatic solar street light controller is 96%. Its fully sealed waterproof design and wide output voltage make it suitable for most LED solar street lamps. It adopts the intelligent power mode, which can automatically adjust the load power according to the battery power and extend the maximum working time of the battery. At the same time, the controller is equipped with various protection settings.
Advantages
The automatic solar street light controller adopts lead-acid battery and lithium battery, which can bear different load power and is applicable to 12V and 24V systems. It adopts infrared remote control and is easy to operate. In order to achieve better energy-saving effect, it also has a four-stage dimming design. Using boost constant current source output, the device can drive up to 18 series LEDs. It can work between minus 40 degrees and 60 degrees, which largely lets you not worry about whether it will break down outside.
