CNM330 series is modular online UPS for sensitive equipment. The single cabinet power rating covers from 10KVA to 300KVA which delivers the best of combination of reliability, 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


Battery Charging capacity:


■ 3.375KW @if the ambient temp is 0 ℃~30℃, No output power duration

■ 3.0KW@if the ambient temp is 30℃-35℃, No output power duration.

■ 2.7 KW@if the ambient temp is 35℃~40℃, No output power duration

Ripple Voltage at battery charging :

Ripple voltage < 1.414%(RMS value)nominal battery voltage at float charging or const voltage boost charging, (notes: battery cable max. long is 10m.)


End Cell Voltage:


1.67V/cell (can be set by Background setting)

Voltage for charge:

Equalize charge: 2.35/cell Float charge: 2.27/cell (can be set by Background setting)


Input power factor:


In all the condition of load and voltage input power factor is 1 .This means that the input current demand lower. So the input cable, air switch demand lower, it will reduce the cost .In addition, because UPS appears as pure resistance of the mains grid power, reduce the operation cost. Most of the traditional system power factor is 0.8, leading to higher front-end costs and operating costs .Require additional capacitors in power factor correction, this is extra spending, lead to lower efficiency. Please see the input voltage and current wave.


Advantage-self aging:


The unit can aging itself in full load condition without any actual load. All the unit will be aging in factory at least 8 hours. Also can be used as AC or DC back feed load to burn-in AC or DC product

The Design Concept of High Efficiency and Energy Saving Environmental Protection

The machine efficiency

Under the condition of the same power module can achieve greater load capacity, can save a lot for the customer at the same time because the cost of efficiency loss, Using the newest switching devices (CoolMos) + intelligent control technology, realize super wide Efficient operation area, under 25% to 100% load rate are in the best running state, especially In a typical 45% to 75% range, efficiency is as high as 96% For customers to save investment.


The whole machine efficiency:


Improve the system output power and the reliability of the system can achieve greater load capacity, better protect customers load equipment operation safety.

Single static bypass

When use multiple independent small power bypass module will produce machine uneven flow caused by bypass module impedance mismatch, so single static bypass design can avoid this problem and can use maintenance switch realize hot-swap when repair UPS, to improve system stability and reliability.
