The use and maintenance of uninterruptible power supplies
(4) on the host to break, break the insurance or burn the device failure, be sure to identify the cause and troubleshooting to be able to restart, or will occur the same failure.
(5) When the battery is found in the voltage reverse polarity, pressure drop, pressure and acid mist leakage of the battery, the timely use of the appropriate method to restore and repair, can not be restored and repair to be replaced, but not different Capacity, different performance, different manufacturers of batteries together, or may have a negative impact on the entire group of batteries. On the life of the battery pack has been expired in time to replace, so as not to affect the host. UPS as a protective power supply, its performance parameters of great significance, should be the focus of our purchase considerations. The mains voltage input range is wide, indicating that the use of electricity is strong (to reduce the battery discharge). Output voltage, frequency range is small, it shows that the mains adjustment capacity, output stability. The waveform distortion rate is used to measure the stability of the output voltage waveform, while the voltage stability indicates the stability of the output voltage when the UPS is suddenly loaded from zero load to full load.
As well as UPS efficiency, power factor, conversion time and so are important parameters that characterize UPS performance, determines the protection of the load and the utilization of electricity. The better the performance, the stronger the protection, in general, off-line UPS on the load protection of the worst, slightly interactive online, online type is almost able to solve all the common power problems. Of course, the cost increases with the performance of the increase. Therefore, users in the purchase of UPS, the load should be based on the degree of power requirements and the importance of different load, and select different types of UPS.
