PWM Solar Universal Controller SL2420

PWM Solar Universal Controller SL2420

Smart  PWM  Solar Charge Controller

The product is suitable for : SL2410/SL2420

Description

1. The design of IP68 waterproof level and aluminum shell helps effectively prevent corrosion.
 
2. System voltage: 12V/24V.
 
3. With LED digital display screen and waterproof switch.
 
4. An upgraded 3-stage PWM charging algorithm is adopted. Overdischarge or application of an equalizing charging to the battery regularly can effectively prevent the battery from non-equalization and sulfuration and extend the lifespan of battery.
 
5. Five load working modes facilitate the product's application to different types of street lights and monitoring devices.
 
6. Support charging sealed batteries, gel batteries, abroach batteries, ternary-material lithium batteries and lithium iron phosphate batteries, etc.
 
7. An external temperature sensor: high-precision temperature compensation function.
 
8. Parameters that have been set will be saved even there is power-down, which makes the setting easy and convenient.
 
9. Designed with status indicators.
 
10. Provide overcharge, over-discharge and overload protectionshort-circuit and reverse-connection protection.
 
11. TVS lightening protection.
