IP68 SRNE 20a stair lighting controller
Features of SR-SL
1.The design of IP68 waterproof level and aluminum shell helps effectively prevent erosion.
2.12 V/24 V system voltage.
3.LED numeric display and waterproof keys are easy to use.
4.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.
5.Up to 5 load working modes facilitate the product's application to different types of road lamps and monitoring devices.
6.Charging program options are available for sealed, GEL and flooded lead-acid batteries and ternary-material lithium and lithium iron phosphate batteries.
7.An external temperature sensor helps deliver high-precision temperature compensation.
8.Parameter settings of power-down saving functions eliminate the trouble of repeated settings, making operation easy and convenient.
9.Various kinds of state indicators.
10.Overcharge, over-discharge and overload protection, as well as short-circuit and reverse-connection protection.
11.TVS lighting protection.
