Working Principal:

Modular UPS use double conversion on-line structure, including rectifier, inverter, battery charger, control circuit, the input and the output battery connector breaker. have function that is input power factor compensation. All modules can be online hot-swappable, providing the highest level of availability, and maintainability.
If one power modular failure will not affect the system normal working, power module can be online hot-swappable all power module paralel is managed by the control board, in accourdance with the unified parameters running, one power module fault can be automatically exit parallel system, will not cause harm to the whole parallel system.

Modular UPS system use independent static bepass module, do not use multiple static bypass structure, avoid caused overload damage modules because of multiple bypass module uneven current when UPS turn to bypass working. The module parallel output volage accuracy is ±1%, parallel circulation current<1%.

Static bypass module contains bypass static switch only, excluded static switch of the amain circuit output; therefore, replacing static bypass modulewill not cause the system power down or transfer manual maintenance bypass, which can realize online hot-swap replacement.
