CNM330 series is modular online UPS for sensitive equipments. The single cabinet power rating covers from 15KVA to 300KVA which delivers the best of combination of reliaability, hot-swappable and flexibility. With the latest IGBT three-level technology and DSP control, CNM330 achieves a high input power factor, low THDi Modular design with N+X redundancy and online hot swapping easy to expand the capacity Full DSP control of high stability, reliability and safety Integrated IGBT module with improved performance and reduced size.

Working principle:

Modular UPS use double conversion on-line structure,including the rectifier, inverter, battery charger, control circuit, the input and output battery connector breaker. Have function that is input power factor compensation. All modules can be online hot-swappable, provide the highest level of availability, and maintainability.

If one power module failure will not affect the system normal working, power module can be online hot-swappable all power module parallel is managed by the control board, in accordance 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 bypass 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.Themodule paralleloutput voltage accuracy is±1%,parallel circulation current<1%.

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