UPS UPS has very important place in contemporary communication power source, it can prolong the life of equipment, assure the safety of data. The electric energy origin of UPS is the chemical power supply that its distribute, the quality discretion that so UPS UPS works, basically depend on the function of its chemistry power source, and be used correctly and safeguard meticulously.

STAND card UPS - the overhaul breakdown phenomenon of 500 UPS of card of a STAND - 500 model when after the UPS involves power source out of service a few days, switching on the mobile phone afresh, hear the sound of relay of ” of bang of bang of Pi of Pi of housing interior “ only, show the tube of power source normally (NOR - MAL VAC) do not shine all the time, and the indication lamp of depress of power source report (BAT - TERY LOW) twinkle ceaseless. Corrective maintenance opens housing to check relay, did not discover a problem.

Change a relay that is the same as model, when appending report again, still be same kind of phenomenon. Examine cell then, the batteries of this UPS power source is comprised by the batteries group of two groups of 12V, 7Ah. Tear open batteries next undertaking that check, discover among them the partial simple case of a group of batteries already burst, electrolyte is already sere. Measure its voltage to be 7.2V. Another group of exteriors are in good condition, its voltage is 10.5V. Because the voltage of batteries is too low,the account that power source of OK and affirmatory UPS cannot start is be caused by. As a result of among them the housing of group of a batteries already burst, reason cannot undertake the overhaul, one in good condition to housing undertakes capacity activation, undertake charging with 0.7A above all, what its voltage rises is very fast, 5 minutes rise to 15.5V, use 0.5A discharge then, put to voltage to be 9.6V, reoccupy 0.5A charges 12h, with 0.5A discharge, time is 5h, its capacity still has 2.5Ah. Charge discharge through circulating a few times, voltage still can rise. Origin: HTtp://tede.cn

Undertake circular full discharging by the following rule: Charge with 0.5A 12h, 0.5A discharge stops to 9.6V, undertake 5 times circular full discharging. The capacity that fills discharge 5 times circularly is 2.6Ah respectively, 2.8Ah, 3.2Ah, 4.5Ah, 4.8Ah. From the point of the result of above, the capacity of batteries group returns Youshangsheng's likelihood. So, reoccupy undertakes 5 times circular full discharging like lower part law. Charge with 0.7A 12h, 0.7A discharge stops to 9.6V, undertake 5 times circular full discharging. The capacity that fills discharge 5 times circularly is 4.9Ah respectively, 5.5Ah, 5.6Ah, 6.2A.h, 6.2A.h. As a result of burst of housing of a batteries, cannot use, the batteries group that buys close of capacity of a 6.2Ah from the market (12V, 7.0Ah) installation use half an year is much, did not discover a problem.

UPS UPS is safeguarded normally can work normally for UPS UPS, in use should notice the following 10 problems. 1. UPS UPS deserves to go up in power choosing should have proper surplus, if be the load of 800W to choose,distribute UPS power supply, its power should of above of 1000w of choose and buy. 2. UPS UPS should avoid a frequent mechanism occasion, had better be in for long switch on the mobile phone condition. 3. The UPS UPS that buys newly wants to have compensatory report to batteries before use, because UPS is in sale process, batteries is discharging oneself ceaselessly, its capacity has very big one part was used up, if undertake not in time filling charging, can affect normal use not only, still can shorten the service life of batteries.
