9 points for attention in Santak UPS uninterruptible power supply1. UPS uninterruptible power supply should be allocated with a certain margin, such as 4KVA load, UPS power supply should be allocated more than 5KVA.
2, UPS power should avoid frequent opening and shutting down, preferably in a long time.
3, the newly purchased UPS power supply should be charged and discharged, which is conducive to prolonging the service life of the UPS power battery. Generally, constant voltage charging is used, and the initial charging current should not be greater than 0.5*C5 ampere (C5 can be calculated by the rated capacity of the battery). The voltage of each battery should be controlled between 2.30 and 2.35V to avoid damage to the battery. The charging current remains unchanged for 3 hours, proving that the battery is sufficient and the general charging time is 12~24 hours.
4. If the auxiliary power supply is always normal, UPS power supply will not work. Its battery may be damaged in long-term floating state. It should be charged and discharged regularly. This can not only activate the battery, but also check whether the UPS power supply is in normal working state.
5. UPS power supply should be checked regularly and floating charge voltage should be checked once a month. If floating charge voltage is less than 2.2V, the battery should be charged equally.
6, always use soft cloth to test the battery to keep the battery clean.
7. Temperature control of UPS UPS power supply during operation, because the temperature range of UPS power supply during operation is controlled within 20 ~25 C, so as to prolong the service life of UPS battery. In the environment without air conditioning, the temperature control of UPS power supply is particularly important.
8, UPS power should be immediately charged after use, so that the battery returned to normal.
9. The distance between the external battery pack and UPS power supply should be as short as possible, and the cross-section area of the conductor should be as large as possible, so as to increase the conductance of the conductor and reduce the power loss on the line, especially when working at high current, the loss on the line should not be neglected.
