Our Advantages
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.
