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. The module parallel output 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.
- Superior energy saving : Efficiency > 96% at 50%-75% rated load, and > 95% at 25% rated load; Input PF > 0.99,input THDi<3%
- Easy-to-install: Top or bottom cabling, no need of input cabling cabinet.
- Easy-to-maintain: Full front access, UPS, failed part can be replaced shortly
- Easy-to-modify: The number of batter y cells can be configured flexibly, so the original batteries can be used when modifying the legacy system; moreover, the battery cell can be replaced in time when it fails without interrupting the normal operation of UPS.
