How much power should I have with my UPS?We must first determine your equipment is much power in general, ordinary PC or IPC power is about 200W, apple at about 300W server between 300W and 600W, the power value of other equipment can refer to the equipment manual.Secondly, should understand the power rating of the UPS has two methods: apparent power (VA) and the actual output power (W), due to the reactive power are so made the difference, the relationship between conversion: apparent power power factor * = actual output powerBackup, online interactive power factor between 0.5 and 0.7, the online power factor is generally 0.8.When UPS is allocated to the equipment, the actual output power of UPS should be matched. Some dealers intentionally or unintentionally confuse (VA) and (W), which should be brought to the attention of the user.
What kind of UPS should I have?According to the purpose of power protection equipment, electrical environment and want to achieve, you can select the appropriate UPS; such as small power equipment of switch power supply general can choose the backup UPS, electricity in the relatively harsh environment where should use interactive online or on-line UPS, and intermittent time or time requirements of sine wave AC equipment is not allowed, it can only be used online UPS.
Why should UPS be equipped?According to IDC statistics, all 45% computer fault is caused by power supply problems; in China, the number of big city blackout for an average of 0.5 times per month, medium city is 2 times / month, a small city or town is 4 times per month, at least nine kinds of problems: power grid, lightning surge, frequency, peak the rate of oscillation, voltage mutation, voltage fluctuation, frequency drift, voltage sag, pulse interference; so from the perspective of improving power quality to a computer equipped with a UPS is very necessary.In addition, network equipment and communication equipment precision is not allowed with intermittent power, to the server as the core network center to be equipped with UPS is self-evident, even an ordinary computer, the use of three months after the data file has exceeded the value of software and hardware, so as to prevent data loss with it is necessary for the UPS.
What kinds of UPS are they?UPS is divided into three major categories: backup, online and online:The backup UPS is the most commonly used, it has automatic voltage regulator, power protection UPS the most basic and most important function, although the general conversion period of about 10ms, inverter output AC square wave and non sine wave, but because of its simple structure and has the advantages of low cost, high reliability, it is widely applied to the computer, peripherals, POS etc.;The on-line UPS structure is complex, but the perfect performance, can solve the problem of power supply, its remarkable characteristic is to continue zero interrupt output pure sine wave AC power supply, can solve all the problems of the peak surge, frequency drift; due to the need for greater investment, usually used in the key equipment and network center of electric power demand harsh environment;[4] modular UPS has many advantages compared with the traditional UPS, on behalf of the development direction of UPS, but also has high cost, reliability and actual part of the product as the theoretical value is high, but the safety factor has been far more than the traditional UPS; research on modular UPS will promote and improve the reliability of the module, thus improve the modular UPS in the customer recognition, to speed up the development of modular UPS. EAST (EAST) modular UPS, each module is an independent work of UPS, power section complete, optional, high efficiency, low interference, environmental protection, energy saving, high safety factor.
What is UPS?UPS is the abbreviation of Uninterruptible Power Supply, which is an important external equipment to provide continuous, stable and uninterrupted power supply.In principle, the UPS is a power electronics device incorporating digital and analog circuits, automatic control inverters, and maintenance free storage devices;Functionally, UPS can effectively purify the city power when the city power is abnormal. It can also supply power to the computer and other equipment for a certain period of time when the city power breaks suddenly, so that you can have enough time to cope with it;From the use, with the coming of information society, UPS is widely used in the information collection, transmission, processing, storage and application to each link, its importance is increased with the increasing importance of information applications.
