15A 12 24V auto Solar Street Light Controller with timer and light control mode-SLC12/24-15

SLC12/24-15 solar street light controller 12/24V 15A adopts PWM (power width modulation) technology. It has 2 modes: timer mode and light mode. when timer mode is working, it can turn on the light after 10s timer delay if sunset, it will also turn the light on before sunrise automatically. when light mode is working, it will directly turn the lamp on when sunset and turn off if sunrise.

Product Features:

-The design of IP22 level and ABS shell helps effectively prevent fire and good cooling.
-12 V/24 V system voltage.
-LED numeric display.
-An upgraded 3-stage PWM charging algorithm applies an equalizing charge to the battery every week, effectively preventing the battery from non-equalization and sulfuration and therefore extending the battery's service life.
-Up to 18 kinds of load working modes facilitate the product's application to different types of road lamps and monitoring devices.
-Charging program options are available for sealed, GEL and flooded lead-acid batteries and ternary-material lithium and lithium iron phosphate batteries.
-An external temperature sensor helps deliver high-precision temperature compensation.
-Parameter settings of power-down saving functions eliminate the trouble of repeated settings, making operation easy and convenient.
-Various kinds of state indicators.
-Overcharge, over-discharge and overload protection, as well as short-circuit and reverse-connection protection.
