CL12/2410LI-D Step-up Constant Current Solar Charge Controller (automatically drop power)
This software introduction applies to CL series solar controller which has CL12/2410LI-A, CL12/2410LI-D, and CL12/2410LI-E. This series are all integrated with LED constant current driver. The maximum conversion efficiency reaches 94%. With fully sealed waterproof design and wide output voltage, the product applies to most LED solar street lights. The output current can be adjusted for 3 time frames.
It is common that the solar street light doesn't work because of the power-lack of battery. CL12/2410LI-D can automatically adjust the load's power according to the left capacity of battery. This increases the working time of the lights.
CL12/2410LI-E has a function of automatic time controlling at dusk and dawn according to different seasons, so you needn't adjust the working time of the lights in different seasons.

Features
1） Automatically adjust the power of load according to the left capacity of battery;
2） Adopt the integrating technology of control and constant current, and save the cost of the LED drive power for users;
3） Wide range of output voltage adapts to the LED lights of a variety of series-parallel circuits;
4） With the function of 3 time frames power regulation, Users can set the working current of LED lights;
5） The controller adopts fully sealed waterproof design. The IP grade reaches IP67. The controller can be used in the water;
6） Flexible and adjustable working parameter makes the controller adapt to different solar systems;
7） External temperature sensor assures real-time temperature compensation;
8） This controller can withstand from -35℃ to 60℃ high and low temperature, so it can adapt to extreme temperature.
Scope of power decrease
12V: If the voltage of battery is less than 12.5V, the controller begins drop power automatically. When the voltage of battery is from 12.5V to 11.8V, the output current of the controller changes linearly from 70%～30% of the setting value. (24V: double the voltage)
Application Scope
12V: solar LED lighting system with max. 170WP solar panel and max. 60W LED light (LED light is from 5 series to 17 series)
24V: solar LED lighting system with max. 360WP solar panel and max. 60W LED light (LED light is from 9 series to 17 series. If the light is 10 series, the max. LED light can be 80W)
CL series are intergrated with LED driver. That means the LED light needn’ t include driver, so the cost of driver is saved. CL series have the function of output current adjustable, and this function realize the load’ s power adjustable. For example, a 30W LED lights can work as follows:
The first time period: 300minutes(5hours) 30W
The second time period: 300minutes(5hours) 10W
The third time period: 180minutes(3hours) 20W
If you use ordinary solar controller, the 30W LED lights will work as follows:
The first time period: 300minutes(5hours) 30W
The second time period: 300minutes(5hours) 30W
The third time period: 180minutes(3hours) 30W
Thus our CL series help save 130Wh.
Suppose the 30W LED lights works 13 hours a day. The sun time per day is 4 days. The rainy days are 7 days. Let’ s compare the configuration bewteen these two solar light system.
