1.Low Voltage Charging 2. RS232/485 3. LCD display 4.Digital intelligent controlle

MAIN FEATURES

1- Perfect protection and alarming function, thus the system has a high stability

2- LCD display function, visually display all operation parameters

3-  Voltage-limiting and current-limiting charging mode, ensures battery in the best charging status

4- PWM stepless unloading mode, which burn the excess power in dump load, making the battery charging in the best status

5- A multiple communication interface selection, realising PC monitoring function. The standard mode is RS232 communication, and other optional model RS485 / Ethernet/GPRS etc

6- Optional wind turbine low-voltage charge function, making full use of low wind power

7- Optional multiple control system function, real-time monitoring the multiple control system at the same time, with well-organized and exact monitoring interface

8- European CE certification
