The power source of UPS power supply is the chemical power supply it is equipped with, so the quality of UPS uninterruptible power supply mainly depends on the performance of its chemical power supply, as well as correct use and careful maintenance.
Before using the newly purchased UPS uninterruptible power supply, it is necessary to recharge the battery. Because the battery is continuously self-discharged during the sales process of the UPS power supply, a large part of its capacity is consumed. Affect normal use and shorten the life of the battery. The method of recharging the battery is to connect the battery in series and charge it according to the specific method provided in the battery instruction manual.
If the battery of the UPS power supply is a non-maintenance-free battery, always check the specific gravity of the solution and the amount of electrolyte, and add electrolyte or distilled water in time.
UPS uninterruptible power supply must have a proper margin in power selection, fully consider the power factor, and the sum of the power of all electrical equipment shall not exceed 80% of the UPS power supply.
The UPS uninterruptible power supply should avoid frequent startup and shutdown, and it is best to stay on for a long time. The load should be started one by one, and it is best not to start the load at the same time.
If the utility power is always in normal power supply, the UPS uninterruptible power supply has no chance to work, and its battery may be damaged by floating charging for a long time. Therefore, the UPS uninterruptible power supply that is not used for a long time should be man-made and forced to work regularly In this way, not only can the battery be activated, but also whether the UPS uninterruptible power supply is in a normal state can be checked, and the operator can be familiar with the use of the UPS power supply system.
The distance between the external battery pack and the UPS should be as short as possible, and the area of the wire should be as large as possible to increase the conductivity and reduce the power loss on the line. Especially when working with high current, the loss on the circuit cannot be ignored.
The UPS uninterruptible power supply must be restored and charged immediately after use, even if the battery returns to a normal state. If the electric energy is not discharged, it can be the termination sign according to the continuous current.
If the user configures the long-delay battery pack by himself, the external charger should have both constant voltage and constant current functions. A charger with only constant voltage function should not be used to avoid affecting the battery life.
Wipe the battery with a soft cloth frequently to keep the surface of the battery clean and hygienic, and prevent dust from entering the electrolyte of the battery through the gap of the battery to pollute the electrolyte, and deteriorate the performance of the battery.
