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.


High Availability Configuration Structure



Static switch module:


■ System standard configuration module

■ Adopts SCR and AC contactor in parallel

■ High reliability, strong overload ability: 1000% for 1 min

■ Transfer time less than 1ms

■ Have strong self-test, inter-lock and full-protection function



Power Module:


■ Freedom choice of capacity configuration according demand, easy to expand

■ Online double-conversion design to ensure the output quality

■ Each module has independent digital intelligent control

■ Each module can work independently

■ Each module has a separate charging system

■ All modules can be hot-swappable, easy for online maintenance

■ Each UPS module provide 4.5KW charge capacity, equivalent to 10 to 12A


Rich Management Interface


Advanced battery management

■ All floating automatic conversion

■ Temperature compensation

■ Discharge to suspend automatic voltage regulation

■ Battery self-diagnosis and self-inspection

■ Battery capacity prediction

■ Discharge time estimates

■ Low voltage forecasting warning



Data recorder


Every 10 ms records a core electrical data, and in Fault occurs, the freezing failure 1 to 1.5 before work. The core of the cycle frequency electrical data Accurately record the cause of failure, to help the accident diagnosis and accurate positioning Rapid diagnosis to improve maintainability, the data will be recorded before a failure or overload occur.



Advanced self-diagnosis


■ Inverter and rectifier circuit working condition monitoring

■ Battery capacity and status detection

■ Equipment working environment temperature testing

■ Ease of maintenance and management of equipment

■ Can each fan of fault detection, and replace the fan without power
