How can Eaton UPS power supply be used to maximize its life?
Eaton UPS power room should be empty and harmonious anti-static floor room, lightning effect is better, dust, moisture, sun protection. The best input voltage is within the planning planning, the most reasonable load planning is 30%-60%, full load, overload will affect the life of Eaton UPS. Maintain it at least once a year. But in fact we are generally difficult to do so thoughtful, and some UPS power maintenance tips is particularly important, such as: prevent dust accumulation inside the chassis, punctuality maintenance power inside the battery and so on, these maintenance tips can often greatly extend the use of UPS power life, cut repair trouble.
1 try not to overload the job. Try to work within the planning with less than extra power, because the overload power will affect not only the life of the load product, but also the life of the UPS power supply it supplies. In general, the load of online UPS power supply should be controlled at 70% ~ 80%, be careful, too light load is not good, although not as severe as overload.
2 punctual maintenance. This is for UPS power inside Eaton battery, as the UPS power inside the center components, we should be more careful maintenance, punctuality maintenance, assuming that local long-term no power failure, it is necessary to punctuality (three months) for continuous power supply, so that Eaton UPS with load discharge. Because for a long time without power, so you always think it is in the normal operation, and in fact, once the power, it can only supply a very short delay even roots in no delay, the reason is that eton battery in the floating charge for a long time.
Check the terminal voltage and internal resistance of each cell on time. For the 12 V battery unit, assume that found in the inspection units difference between the battery terminal voltage exceeds 0.4 V above or electric resistance exceeds 80 m Ω above should be balanced for each cell battery to charge, to restore the battery internal resistance and eliminate the battery terminal voltage imbalance between each unit. When balanced charging, the charging voltage is 13.5 ~ 13.8v. Treated with outstanding balance charging the battery can be resistance to the vast majority of 30 m below the Ω.
4 cut deep discharge, battery life is closely related to the depth of its discharge. The lighter the load carried by the UPS power supply, when the mains power supply is continuous, the greater the ratio of the available capacity of the power storage to its additional capacity.
5 use power supply peak charging, about UPS power supply in the city for a long time low voltage power supply or frequent power failure of the user, in order to prevent the battery due to lack of long-term lack of premature damage, should be full use of power supply peak (such as late at night time) to charge the battery to ensure that the battery in each discharge after a satisfactory charging time. Generally, after deep discharge, the battery is recharged to 90% of the additional capacity, which requires at least 10 ~ 12h.
