1. Current,working time and the power can be adjusted by one key, very easy to use.
2. Constant current LED source is internally installed and its efficiency can reach 96%.
3. Smart power mode can adjust load power automatically by battery energy,it can extend the battery working time to max.
4. Outstanding ripple current control and degree of linearity control utmost lessening the LED light decline and increase LED life span.
5. IP 68 waterproof level and aluminum outer shell is able to effectively prevent various kinds of corrosion.
6. The output voltage is 60V, which can drive 18 LED lamps installed in series.
7. With modified calculation of charging, the charging efficiency is improved, which lengthen the using time of solar energy.
8. Unique test mode. One key operation realizes the power switching.
9. The metal outer casing design with high power density which make the unit volume to obtain maximum power also can control the temperature rise effective.
10. Varies system protection function.
