Detailed introduction

1. Exclusive controller for Lithium Battery, which suit for ternary Lithium, Lithium iron battery, Lithium cobalt oxides battery, etc.
2. Unique Lithium battery which is automatically actuated.
3. Flexible charging mode, equalizing charge or PWM charge auto switch.
4. Lithium battery low temperature charging protection, when the ambient temperature is lower than 0℃, the controller will auto stop low temperature charging so as to protect the battery.
5. Digital high precision constant-current control, the maximum efficiency can reach 96%.
6. The working current can be adjusted from 0.15A to 3.3A, the regulating precision is 30mA.
7. High dynamic performances of load insure current output stability even though the battery voltage and load sudden change.
8. 3 level time frame dimming function design, work time can be set range from 0 hour to 15 hours, power can be set range from 0% to 100%.
9. Intelligent power mode, the load power can be adjusted automatically according to the battery power, can extend the maximum working time of the battery.
10. Record the system status, can record at a max 7days and monitor the whole system.
11. The true constant current but not limited current, which can insure the current output stability thus decrease LED light failure and increase the LED service life.
12. Metal case, IP68 waterproof degree, can be used in all kinds of bad conditions.
13. Overheat protection function, when the controller reaches a certain temperature, it will decrease or close the load.
14. Varies system protection. Including the battery reverse connection, LED short circuit, open circuit protection and so on.
