The changes of the times have made the information equipment more stringent on the grid environment. As an important equipment to improve the grid pollution, UPS power supply has also ushered in a broader market demand. For users who have used UPS power supply, how to maintain the UPS power supply and increase its service life is the first and foremost condition.

UPS power equipment maintenance, what is the maintenance?

Maintenance of the site When installing and using the UPS power supply, the temperature of the installation environment should be 0~40°C, the relative humidity is 30%~90%, the temperature is lower than 0°C or damp, and the insulation performance of the UPS power supply will decrease, which will easily lead to short circuit. At the same time, it may cause corrosion and rust of connectors, electrical connection screws, component pins, hoes, solder joints, etc. of UPS power supply and other equipment. Altitude > 1000m, 10% derating per 1000m. In addition, the UPS’s anti-magnetic capability is not very good. Therefore, do not place strong magnetic objects on the UPS. Otherwise, the UPS will not work properly or damage the machine.

Battery Maintenance The battery is the UPS power supply as a means of storing electrical energy. The size of the battery determines the duration of the discharge.

Maintaining a suitable ambient temperature for all aspects of consideration, UPS power supply is generally a maintenance-free lead-acid battery, the life expectancy is generally about 5 years. The ambient temperature of the battery is between 20 and 25 ° C. Once it exceeds 25 ° C, the battery life is reduced by half for every 10°C increase.

Regular charging and discharging of batteries In the environment where power supply blackouts rarely occur, the battery will be in a floating state for a long time. Over time, the activity of mutual conversion of chemical and electrical energy of the battery will be reduced, and the aging will be accelerated to shorten the service life. Therefore, it should be completely discharged every 2-3 months, and the discharge time can be determined according to the capacity of the battery and the load. After a full load discharge is completed, recharge for more than 8 hours as specified.
