How to choose the high capacity UPS for financial enterprises?

At present, uninterrupted power supply UPS has been widely used in various aspects of the financial industry. High capacity UPS power supply specifications are varied. With the concentrated application of a large number of servers and minicomputers in the financial industry, the role played by UPS power has also changed. From the early stage, only the problem of power interruption was solved, has been transition to the problem of power interference, which provides high-quality, non-interfering and uninterrupted power supply for a large number of servers and other communication equipment in the computer room.

First, What are the main functions of the uninterrupted power supply UPS? Its main role of UPS power supply can be summarized into the following five aspects:   

1. Uninterrupted switching between dual power supply, double conversion online ups is select-able.

2. The isolation function blocks the grid interference such as instantaneous interruption, harmonics, voltage fluctuation, frequency fluctuation and noise before the load, make the load does not cause interference to the grid, and the interference in the grid does not affect the load.

3. Voltage conversion function, the UPS power supply can provide the stable output voltage different from the input voltage.

4. Frequency conversion function, the no break UPS power supply can provide the stable output frequency different from the input frequency.

5. UPS power supply with battery which can support some certain backup time.

Second, What problems should be paid attention to the large UPS power supply selection?

In the selection of medium and large UPS power supply, we should pay attention to the following main indicators:

1. Power distribution system. There are many power distribution systems for UPS. Medium and large high capacity 3 phase UPS power supplies should adopt three phase 380VAC input and three phase 380VAC ouput power distribution system.

2. Input and output specifications. These include voltage and frequency specifications. The output voltage and frequency must be within a certain range, and the the input voltage and frequency range is wider, it is better.

3. Isolation transformer. To solve the problem of interference to the load, zero ground voltage and isolation. Generally large high capacity UPS power supply is equipped with an output isolation transformer as standard. If the impact and interference to the power grid are taken into consideration, the large UPS power supply can be equipped with an input isolation transformer.

4. Anti-overload capability. This is one of the most important output indicators for UPS power supplies. 

5. Allow the mains voltage waveform distortion, the online UPS power supply must be adapted to various mains environments.

6. The output voltage waveform distortion. The power supplied by the UPS power supply to the equipment should be very pure. The higher the distortion, the worse the power purification capability of the UPS.

7, The output voltage imbalance, for the UPS power supply, regardless of whether the input is out of phase, the output voltage imbalance is as small as possible, should supply the load three-phase balanced power supply.

8. Output current peak (surge) coefficient. Many loads have a secondary power supply. If these power supplies simultaneously draw current at the peak of the sine wave, a pulse with a large instantaneous peak ratio will appear. If the peak value of the output current of the UPS system is small, it cannot withstand such an impact, and only transfer to bypass causes the UPS power supply system to collapse.

9. The system operating efficiency. A low efficient UPS inverter power supply indicates that more energy is being consumed, and that will greatly increase the failure rate of the UPS.

  11. The output power factor. The output power factor is the ability to adapt to different type loads. The ideal output power factor is zero for both lead and lag, which also means it can carry any type of loads.

12. Average time between failures. The longer the average time between failures, the better.

13, Working environment temperature. The UPS power supply can adapt wider the ambient temperature range wider, the better.

14. Noise (at 1 meter). The noise generated by the UPS power supply is smaller is better.

15. Monitoring software. The UPS power supply should be equipped with fully functional and easy to use monitoring software.
