System performance characteristics

1. Modular design, the charging device uses multiple high-frequency switch modules in parallel, N + 1 hot backup, smooth capacity expansion and hot plug. The module has an integrated interface to improve the stability and reliability of the system.

2. The monitoring function is perfect and highly intelligent. It adopts large screen LCD Chinese character display, with touch function and audible and visual alarm.

3. Fully intelligent design to realize full parameter local and remote monitoring of all components of the system: AC power distribution, rectifier module and DC feed; The main monitoring quantities include: module on / off, charging mode, output voltage regulation, output current limiting point setting, automatic battery management, etc.

4. The monitoring system is equipped with standard RS-232 / 485 interface and adopts the standard communication protocol of the Ministry of electric power to facilitate access to the automation system, provide open protocol, facilitate networking, and simply realize "four remote" and unattended.

5. Automatic management and maintenance of battery: real-time monitoring of terminal voltage, charging and discharging current of battery pack, automatic control of single battery voltage, floating charge and regular maintenance.

6. It has the function of battery temperature compensation.

7. The rectifier module is easy to operate and use, and can be plugged in and out with power, which is more convenient for installation, maintenance and replacement.
