battery monitoring system BMS

Suitable for large sized UPS batteries
With a flexible expanding system, iPQMS can supervise an emergency power supply and up to 448 cells of battery strings in real time with one monitoring/control unit. This reformative expansion capacity allows the user to arrange and install the whole system with ease, thus saving a great amount of installation expenses.
Monitor Min. 50cells to Max. 448cells per system
Application: Power plant, Substation, IDC and etc
