Flexible Modular UPS System Parallel Redundancy Online UPS CNM331 Series 30-300KVA

​The CNM331 series three phases input and three phases output UPS,adopted modular design and the N+X parallel redundant technology,the capacity from 20KVA to 300KVA. This series of UPS products can almost completely solve all the power problems such as power off, high voltage, low voltage, instantaneous voltage drop, reduce the oscillation, high voltage pulse, voltage fluctuations, surge voltage, harmonic distortion, clutter interference, frequency fluctuations etc. This product is suitable for a wide range of applications, for example: computer equipment, communication systems and automation equipment etc.
Digital control
All parts of the series architecture using digital control,the performance indicators of UPS are very good and the control system more reliable.
19 inch standard cabinet can perfectly match the application environment of data center
N+X parallel redundant of power module
The quantity of power module can set freely. When the power module more than 2 pieces use on parallel, the system availability reached 99.999%,the MTBF will be over 250,000 hours
Control system parallel redundant
Each power module uses an independent control system,the power module of UPS is controlled independently based on the information shared by each other. Suppose any power module fails, it can be disconnected from the parallel system immediately. It will not cause harm to the complete system.
Support to use on parallel, maximum 4 cabinets
Optimized distribution bus cabinet to ensure the safety when use on parallel
Separate bypass for each power module
Common use battery bank when several UPS power modules or UPS cabinet use on parallel
Intelligent battery management
