Specifications

Ⅰ. Main features 

1. IP 68 waterproof level and aluminum outer shell is able to effectively prevent various kinds of corrosion.
2. Automatic identification of 12V/24V system voltage
3. LED digital display and waterproof key-operated operations, which makes use simple and convenient
4. Ternary form charging algorithm to equally charge storage battery every week, which can effectively prevent 
5. batteryfrom imbalance and vulcanization so that service life of battery can be prolonged.
6. Five working modes which make it convenient to use the product on various kinds of road lamps and monitoring 
7. devices.
8. Externally installed temperature sensor is capable of high-accurate temperature compensation.
9. Parameter settings can be stored if there is power failure.No need for repeated setting. Usage is simple and convenient.
10. Various kinds of status indication
11. Protection against over-charge,overdischarge and overload, protection against electronic short circuit and reverse connection
12. TVS lightning protection
