SRNE Street Light Charge Controller15a Auto Smart Street Light Regulator
Best selling IP68 waterproof 12V/24V 10a auto intelligent street light controller
Features of SR-DH20/50/100
1. New design of wireless remote-control can modify the controller parameter and read the system message according to the handheld device.
2. Digital high precision constant-current control, the maximum efficiency can reach 96%.
3. The working current can be adjusted from 0.15A to 3.3A, the regulating precision is 30mA.
4. High dynamic performances of load insure current output stability even though the battery voltage and load sudden change.
5. Three 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%.
6. Intelligent power mode, the load power can be adjust automatically according to the battery power, can extend the maximum working time of the battery.
7. Record the system status, can record at a max 7days and monitor the whole system.
8. The true constant current but not limited the current, insure the current output stability thus decrease LED light failure,increase the LED service life.
9. Metal case, IP68 waterproof degree, can suitable use in all kinds of bad conditions.
10. With modified calculation of charging, the charging efficiency is improved, which lengthen the using time of solar energy.
