Correct use of uninterruptible power supply

Correct use of uninterruptible power supply: If the load exceeds 96%, the buzzer will beep once every 0.5s. At this time, the load should be reduced, and useless equipment should be turned off or cancelled. In battery mode: In the battery power supply state, the battery loses power, the load/battery 2, yellow 1 lights are on, the buzzer will gradually turn into a long beeping state, the output will be automatically cut off, and the UPS power supply will automatically shut down. Abnormal mode: The fault indicator is on during operation, indicating that the UPS power supply is in abnormal mode. At this time, all loads should be disconnected, and the equipment should be connected to other power supply lines first, and the UPS power supply should be turned off. Report the failure to the maintenance personnel of the automatic station, and wait Professionals handle it, and don't continue to supply power with faults. The reason why the UPS cannot be charged may be the need to change the battery. UPS power supply ideal constant humidity 20-25 degrees environment, charging and discharging is not frequent (no more than two or three times a month), the battery should be maintained regularly, and the battery and UPS should be used for more than 5 years if the quality is good. Therefore, according to this situation, it is very likely that the battery needs to be replaced.

Efficiency is a key indicator of UPS, especially large-capacity UPS. It is the ratio of the output active power to the input active power under full load (resistive). The higher the nominal output power of the UPS, the higher the system efficiency. Small capacity double conversion online UPS.

Battery indicator selection, internal resistance: The battery with a small internal resistance should be selected so that it can continue to discharge with high current. If the internal resistance is large, the power consumption will increase during charging and discharging, causing the battery to become hot. Float charge voltage: At the same temperature, a high float charge voltage value means large energy storage, and the float charge voltage value of a poor quality battery is generally small. The battery float voltage value should be corrected at different temperatures. In large and medium-sized (several kVA-several thousand kVA) UPSs, 2V single-cell series batteries are used to avoid the use of small-capacity combined batteries for hybrid connection.

A central computer room with a high degree of automation, with a wide variety of lines, adopts integrated wiring solutions to route the lines of air conditioning, power supply, fire protection, lightning protection, monitoring and lighting systems, and conduct unified design and construction to make the structure clear. It is convenient for centralized management and maintenance. It not only improves the working capacity of the equipment but also facilitates the expansion of users, and improves the usability and reliability of the system. In general, the solution is a data center area protection and scalable system solution, which can optimize the construction investment of the data center, and make the data center have higher adaptability, availability, reliability, scalability and lower Maintenance costs.
