Nowadays, the UPS power will not show up when it is powered down, more cases are uninterrupted. Some faults often occur often, if the UPS power is faulty, it cannot provide protection for the load. In the process of daily processing UPS power repair, we can find that there are many UPS failures due to factors such as batteries, mains, usage environments and methods, have a considerable part of the UPS itself does not fail.
If these factors can be found, it is not due to the failure phenomenon caused by UPS, and can solve the customer more quickly. These five factors may cause the UPS power supply to malfunction! 1, the UPS power supply is stored even if the UPS power is not used, its life will begin to decrease. That is because the lead-acid UPS power will automatically release a small amount of energy.
In order to extend the storage life of the UPS power supply, it is recommended that you charge it every three to four months. If you don't do this, you may see permanent capacity loss in just six months. It is also possible to extend its service life by saving unused UPS power supplies at 50 ¡ã F (10 ¡ã C) or lower.
2, the ambient temperature is too high, the rated capacity of each UPS power supply is based on ambient temperature of 25 ¡ã C (77 ¡ã F). Any change (especially temperature increase) affects performance and service life. Typically, for the recommended ambient temperature, each liter is 15 ¡ã F, the expected life of the UPS power will be reduced by 50%.
For the UPS power supply, the working environment should be the same as the working environment of the computer, the temperature should be controlled above 5 ¡ã C, 22 ¡ã C or lower; relative humidity is controlled below 50%, and the upper and lower amplitude is not more than 10%. Routine maintenance check can help discover hotspots and verify ventilation. 3.
After the over-cycle UPS rely on the UPS power supply operation during the power failure, the UPS power is charged for future use, referred to as discharge cycle. After installing the UPS power supply, the UPS power will reach 100% of its rated capacity. However, each discharge and subsequent charging will slightly reduce the capacity of the UPS power supply.
4. Floating voltage is incorrect Each UPS power manufacturer will designate a charging voltage range for its UPS power supply. If the UPS power is continuously charged outside of these parameters, it may cause serious damage to it.
Insufficient charging or high voltage can cause sulfate crystals to form on the UPS power board. Over time, these crystals will harden and reduce the available capacity of the UPS power supply. Excessive floating voltage can lead to excessive hydrogen and oxygen, which may cause internal to dryness, once accelerated, the internal change can cause thermal out of control, resulting in failures and even fire.
5, the UPS power supply is dedicated to UPS using incorrect UPS power supply, just like other UPS power supplies to its respective appliances. Any power supply has its unique set of rules and regulations and methods during use, for us to use. UPS uninterruptible power system service life is closely related to the use of the situation, so you must pay attention to methods and maintenance in norm.
