The availability of UPS power is reflected in the proportion of the normal operation time of the UPS uninterruptible power supply to the whole time during a certain period of use. To improve the availability of the UPS, it is possible to increase the mean time between failures of the UPS and reduce the mean time to recovery of the UPS. In order to ensure the normal operation of the data device.

To improve the mean time between failures of the UPS power supply, by improving the specifications and grades of the logic control components inside the UPS, and using the advanced main circuit structure, it should be more intelligent in the management and communication of the UPS. Under the process of ensuring the normal operation of the UPS, many tests are carried out to improve the production process, find shortcomings in practice, and continuously improve the availability of the UPS. However, through the above technologies, there is no obvious effect when the mean time between failures of the UPS is increased to a certain extent.

To reduce the average recovery time of UPS power supply, it is possible to carry out maintenance of key components within a regular period of time, and to replace corresponding components if necessary. At the same time, it is necessary to improve the requirements for maintenance and operation personnel, which can further reduce the probability of UPS failure. In terms of UPS procurement, corresponding procedures should also be followed, and manufacturers are required to make strict commitments to after-sales service. Improving UPS power availability can also be a modular, structured design of UPS power. Of course, the integrated design can also improve the availability of UPS power supply to meet the needs of various equipment to form a power supply system. The integration can be reflected in the centralization of the management of the power supply status in all aspects of the power supply equipment system, the unification and standardization of the manufacture and supply of the power supply equipment, and the standardization of the integration and connection of the power supply equipment and the rack structure including the load.
