High Frequency Online UPS for Small and Medium-Sized Data Centers

CNH331 Serious High Frequency Online UPS

                   

Application:

    High frequency online UPS is applicable to small and medium-sized data centers, network management center, computer rooms for enterprises, or able to provide to solutions to conditions like voltage instantaneous drop-off or damping concussion, high-voltage pulse, voltage pulsation, surge voltage, harmonic distortion, and frequency fluctuation.
    Each single phase of the CNH331 serious UPS is converted to DC through an individual PFC circuit and then transferred to AC through inverter for output. At the same time, a separate controller is provided for the real time control and the data collection of the PFC circuit so that the whole system can operate more harmonious or feedback the system state to the customer more promptly. In addiction, the controlling of the battery charging can extend the battery serve lifetime effectively and the twin channel line input improves the system's reliability.
    Furthermore, series products is enhanced with excellent performance in protection level, which ensures the stability of UPS working in the industrial environment with large dust.

Fey Features:

    Excellent performance in industrial environment protection
    Just with standard products, IP21 protection level (protection the machine from the intrusion of solid material with diameter larger than 12mm or the water drops) is achieved. If a higher protection is required, the optional dust-proof accessories can help to increase the protection level in industrial environment and safeguard the UPS's security of operation in bad environment.
 

Specifications:
 
N=X parallel redundancy(compatible to battery share in the parallel mode):
The maximum of the  input parallel mode is 8 UPS without any other external accessories, which help the customer to extend the system capacity with low cost. N stands for the minimum amount of UPS in the load and X stands for the amount of redundant UPS in the system. The bigger the number of the X is, the higher the reliability of the system will be.
The advanced controlling strategy is adopted to save the customer's investment by sharing a battery unit in the parallel redundancy mode.
 
Intelligent management of battery charging and discharging:

The CPU controlled advanced intelligent charging of battery enables the UPS's charger to rectify the charging the parameter, and provide the optimum charging modes in the answer to the environment, types and the amounts of the cells, and the using condition of the battery. The scientific charging mode extends the battery's service lifetime. The optional addiction to charging units shortens the time duration for the battery units recharging.
 
Frontal-=board operation and maintenance:

The full consideration of customer's efficiency in using the UPS is embodied in the module design and frontal-board maintenance, which save time for the repairing and improves the machine's usability.
Twin-channel Line Input
The UPS provides customer security in the power supply with intelligent choice between two-line input or one-line input according to the actual condition.

Remote monitoring:

Communication interfaces like RS232/RS485, Intelligent Slot are provided and CMC, WebPower cards of CONSNANT company are available for the realization of the remote management and monitoring. In addiction, the optional AS400 card is suitable for the connection of stem point, which enriches the customer's choice out of the monitoring demand.

High-efficient DSP chip:

The digital Ti DSP controlling chip provides precise data processing capability with excellent perform

Outstanding electric property:

The efficiency of the machines is as high as 93% and reaches over 98% in the ECO mode, which can help to reduce the power loss of UPS
The CNH331 series UPS is designed according to China's power grid with a broader range of input voltage from 210VAC to 475VAC, which ensures that it can be applicable in the awful grid environment or different power supply equipment like generator with its extraordinary input frequency.
The factor that the technology of IGBT FM intelligent rectifier and inverter is used, the input,  the input factor is as high as 0.99, and the input current harmonic wave is as low as 3% makes the output voltage electric property more extraordinary.
Power overload capacity: the UPS can work normally under the condition of 110-240% load to 10 minutes, and 1 minute in the condition of 125-150% load. It also has the output short protection capability.

Flexible battery arrangement:

Flexible arrangement of the amount of accumulations in each battery(32,30, or 28)can be achieved through the parameter resetting in the CNH331 series UPS, which effectively solve the question that the damage of some individual cell may influence the life of whole battery unit by eliminating the damage ones from the unit in the process of using UPS
   
Three phase input and three phase output high frequency online UPS from 20KVA to 80KVA
