How to choose the UPS power supply for IDC data center?

Tag: How to choose the UPS power supply of IDC data center? 1. It is necessary to estimate the power of the UPS power supply. According to the power consumption of the microcomputer and its external equipment, calculate the total power consumption of the equipment, which is often referred to as the total load of the power supply. Multiplying the total power consumption by the safety factor is the estimated power of the UPS power supply. The general safety factor is generally 1.2-1.3. 2. The choice of domestic and imported UPS power supply is in the choice of domestic and imported UPS power supply. It is generally recommended to use domestic UPS power supply. In recent years, the quality of domestic small UPS power supplies has been greatly improved. The choice of domestic small UPS power supply is on the one hand to support the country’s economic and technological development, on the other hand, it has great convenience in maintenance, such as complete spare parts, and satisfactory maintenance capabilities and speed. Imported UPS power supplies are generally of good quality, but due to the difficulties in maintenance technology and spare parts, once a failure occurs, they often cannot be repaired in time, and they cannot be used for long periods of time. In terms of working performance, domestic UPS power supplies are more in line with domestic power supply conditions. For example, some types of UPS power supplies have a relatively wide input voltage range and have a stable output function, which can adapt to some environments with poor power supply conditions in our country. The electronic engineering construction of the People's Bank of China proposed the policy of adopting domestic UPS power supply, which is undoubtedly a good start. 3. The choice of online and backup UPS power supply should be based on the needs of microcomputer equipment and economic conditions. If the economic conditions are good, you can choose the online UPS power supply; if the economic conditions are bad, but it does not affect the normal operation of the computer, the backup UPS power supply can also be selected. 4. The choice of long-term and short-time power supply UPS power supply The choice of long-term power supply UPS power supply and short-time power supply UPS power supply mainly depends on economic conditions and the needs of use. If the economic conditions are good, a long-term UPS power supply can be used, otherwise, a short-time UPS power supply plus a small generator set can be used as a backup power supply. 5. Understand the power supply status of the UPS power supply site Before selecting the UPS power supply, it is necessary to understand the power supply status of the UPS power supply site. General UPS power supply requirements for mains input are: input voltage 380V±10% or 220V±10%; frequency 50±0.5Hz. If the power supply of the site is lower than this standard, a UPS power supply with a wide input range should be selected, or a stabilized power supply or voltage regulating device can be installed in the front of the UPS power supply. 6. Issues that should be paid attention to when choosing a backup UPS power supply. When choosing a backup UPS power supply, special attention should be paid to the switching time of the power supply. The switching time mainly reflects the switching time of the UPS power supply and the requirements of the microcomputer for the switching time. If the selection is improper, the microcomputer will stop when the mains power fails, and it will not function as an ups power supply. 7. 'Shop around' and choose the best one. At present, there are many manufacturers and sellers of small UPS power supplies. The product quality is not uniform, and the price varies greatly. Therefore, more consultation and investigation should be made to determine the technical indicators of different products. Make a careful comparison with the performance-price ratio; make a 'shop around' to choose the best. 8. Problems that should be paid attention to when selecting imported UPS power supply. Some imported UPS power supply has different input and output wiring methods than our country, so attention should be paid to the method of improvement when selecting it. American UPS power supply, such as PulSe (PulSe), Exide (EXIDE) and other models of UPS power input and output wiring methods are contrary to my country's standards. To put it simply, my country's single-phase power supply is left and right, while the United States is left and right. In addition, it should be noted that the style of American standard socket plug is different from that of our country. When the American national standard plug and socket is changed to my country's national standard plug and socket, attention should be paid to the internal connection relationship, and the wires cannot be simply adjusted. 9. Convenience during maintenance is also a factor in the selection. It is a normal phenomenon that UPS power supply fails. In the selection, the convenience of maintenance is also a factor that cannot be underestimated, otherwise it will bring inconvenience to maintenance in use.
