Five factors may lead to the premature failure of Schneider UPS power supply

Five factors may lead to premature UPS failure

These five factors may lead to premature UPS failure! Nowadays, the UPS power supply is not in the power failure will show their skills, more of the case is uninterrupted power supply. UPS power supply itself often has some faults. If UPS power supply fails, it cannot provide protection function for load. In this article, energy storage electrical small series for you to introduce Schneider UPS premature failure of several reasons.

These five factors may lead to premature failure of apcups power supply!

In the process of daily treatment of apcups power supply maintenance, we can find that many ups failures are caused by the factors of battery, power supply, use environment and use method, and a considerable part of Schneider UPS power supply itself has not failed. If we can find out these factors and judge that they are not caused by UPS, we can solve the problem for customers more quickly.

1. Bad storage of Schneider UPS

Even if Schneider UPS power supply is not used, its life will start to decrease. That's because the lead-acid ups will automatically release a small amount of energy.

In order to extend the storage life of Schneider UPS power supply, it is recommended that you charge it every three to four months. If you don't, you may see a permanent capacity loss in just six months. You can also save the unused UPS power supply in 50 ° F（10 ° C) Or lower temperature to extend its service life.

2. The ambient temperature is too high

The rated capacity of each UPS power supply is based on 25 ° C（77 ° F) The temperature of the environment. Any change (especially the temperature rise) will affect the performance and service life. Generally, for every 15% increase in recommended ambient temperature ° F. The life expectancy of UPS power supply will be reduced by 50%.

For Schneider UPS, the working environment should be the same as that of computer, and the temperature should be controlled above 5 ℃ and below 22 ℃; The relative humidity should be controlled below 50% and the range should not exceed 10%. Routine maintenance checks can help identify hot spots and verify ventilation conditions.

3. Excessive circulation

When UPS runs on UPS power supply during power failure, apcups power supply will be charged for future use, which is called discharge cycle. After installing the UPS power supply, the UPS power supply will reach 100% of its rated capacity. However, each discharge and subsequent charging will slightly reduce the capacity of UPS power supply.

4. Incorrect floating voltage

Each UPS power supply manufacturer will specify the charging voltage range for its own apcups power supply design. If Schneider UPS continues to charge beyond these parameters, serious damage may result. Insufficient charging or low voltage will cause sulfate crystals to form on UPS power board.

Over time, these crystals will harden and reduce the available capacity of the UPS power supply. Too high floating charge voltage will lead to too much hydrogen and oxygen, and may lead to internal drying. Once accelerated, internal drying will lead to thermal runaway, leading to failure and even fire.

5. Incorrect use of apcups power supply

Apcups power supply is dedicated to UPS, just like other Schneider UPS power supply is dedicated to their respective electrical appliances. Any power supply in the use process has its unique set of rules and regulations and methods for all of us to use. The service life of Schneider UPS is closely related to the service condition, so we must pay attention to the methods and maintenance in normal use.

Precautions for UPS maintenance

The maintenance and use of ups are inseparable. If there is a scientific way of use, there should be correct maintenance methods, so as to achieve the high utilization rate of Schneider ups.

1. The maintenance of Schneider UPS must be carried out under the condition of shutdown, so as to avoid the equipment failure caused by ionization of internal high voltage and IGBT triggered by charged particles.

2. If the UPS power supply with maintenance bypass can be transferred to maintenance bypass, but the internal power is still charged at this time.

3. UPS power supply must be self discharged before maintenance.

4. Maintenance tools can use vacuum blower, do not use wet cloth.

When the ups battery system fails, the reason should be found out first, and the load or UPS power supply system should be distinguished; Host or battery pack.

Pay attention to safety when maintaining Schneider UPS power supply. When dealing with power supply equipment, even a small operation error may cause serious injury. Therefore, when dealing with UPS power supply, safety rules should be observed: including following the recommendations of equipment manufacturers, paying attention to the special details of facilities and standard safety guidelines.
