< p > while matching KEBO UPS power supply, large enterprises should pay attention to the following main indicators: < / p > < p > 1, UPS uninterruptible power supply, power supply and distribution system, a lot of, large UPS appropriate USES SanJin ( 380V) And three out of the ( 380V) The power distribution system. < / p > < p > 2, isolation transformer. To solve the problem of load disturbance, the problem such as zero voltage and isolation, general big UPS standard equipped with output isolation transformer, if considering the impact on the grid and interference, matching the input isolation transformer. < / p > < p =“文本-风格 align:中心; '> < / p > < p > 3, the output voltage imbalance degree. For UPS, whether or not the input phase, the imbalance of the output voltage as small as possible, should be a balance of three phase power to load. < / p > < p > 4, magnetic compatibility features. Choose those who passed the emc test of UPS, reduce the pollution of the electronic equipment of power grid and the radiation of human body, avoid influencing other equipment normal work, at the same time, UPS itself will also have the ability to resist other equipment interference. < / p > < p > 5, the output power factor. Output power factor is the ability to adapt to different load, the ideal output power factor is advanced and the lag is zero, it also suggests that it can take any nature of the load. < / p > < p > 6, mean time between failures. The average time between failures as long as possible. < / p > < p > 7, monitoring software. UPS is equipped with a fully functional, easy to use monitoring software, for domestic users, monitoring interface is essential for all Chinese requirements. < / p > < p > 8, battery. Large UPS should have battery intelligent management function, at least should have regular self-inspection and automatic battery maintenance, all charge/floating automatic conversion, automatic temperature compensation, and other functions, to extend battery life. < / p > < p > English abbreviation is UPS uninterruptible power supply, is able to provide sustained, stable and uninterrupted power supply for computer room of the important external devices. And improper habits will affect the performance of the UPS and the stability of work, also will appear UPS monitoring system of false positives, so KEBOUPS power supply in daily use should follow the scientific practice. < / p > < p > ( 1) Put UPS power supply facilities should avoid direct sunlight, and adequate ventilation space, in addition, also banned in the UPS output port connect with perceptual load. < / p > < p > ( 2) When using the UPS power supply, should strictly follow the manufacturer's product data sheet to use, to ensure that all wiring all meet the requirements of the relevant user may not arbitrarily change the order of each other. Otherwise may cause UPS alarm monitoring system errors. < / p > < p > ( 3) Use UPS power supply is in strict accordance with the switch machine in order to operate correctly, to avoid UPS power supply because of the sudden plus was caused when the load suddenly suddenly or reduce the load of UPS power supply voltage output volatility, and make the UPS power supply cannot work normally. < / p > < p > ( 4) Banned frequently switch UPS power supply, the use of general requirement is that after turning off the UPS power supply, must wait at least 6 seconds to restart the UPS power supply, otherwise it may make the UPS power supply enter & quot; Boot failure & quot; State, that is, UPS power supply without no mains electricity output, nor the state of the inverter output. < / p > < p > ( 5) Prohibited to use UPS power over load, manufacturer recommendations: large start when start UPS power load are controlled within 80% as far as possible, if use, overload in the condition of inverter, often breakdown transistor inverter. The practice proved: for the vast majority of UPS power supply on the market, within the scope of 30% ~ 60% rated output power is a better way to work. < / p > < p > ( 6) On a regular basis to maintain: UPS power supply UPS power dust inside, measure the battery voltage, replace the old or the unqualified batteries, check the fan operation condition and testing by adjusting the parameters of the UPS system, etc. < / p > < p > < / p >
