Product Description
Waterproof Solar Street Light Controller Solar controller for Lithium Battery(QW-SR-DH50-LI)
Product Feature
1. New design of wireless remote-control can modify the controller parameter and read the system message according to the handheld device.
2. The date communication adapted multiple handshake protocol and date compression, it makes date transmission exact and fast.
3. Fast dynamic response of the load, the load stabilization time is very short.
4. 3 section time frame dimming function design, work time can be set range from 0h to 15 hours, power can be set range from 0% to 100%.
5. High efficiency constant current source, the Max. Efficiency can reach 97%.
6. Intelligent power mode, it can automatically adjust the load power according to battery electric quantity, which can extend battery's service life.
7. The true constant current but not limited the current, insure the current output stability thus decrease LED light failure, increase the LED service life.
8. Metal case, IP68 waterproof degree, can suitable use in all kinds of bad conditions.
9. With modified calculation of charging, the charging efficiency is improved, which lengthen the using time of solar energy.
10. Overheat preventing function, above a certain temperature will decrease the load or close the load.
11. Varies system protection function. Including the battery reverse connection, LED short circuit, open circuit protection and so on.
