       In information technology (IT) infrastructure, UPS (uninterruptible power supply) systems play a vital role, ensuring that critical equipment and services continue to operate during power outages. In order to maintain the reliability of your UPS system and extend its service life, it is crucial to understand the common causes of UPS failures and take professionally recommended solutions.

 

1. Core components of UPS system

The UPS system mainly consists of the following core components:

     Rectifier: Converts alternating current (AC) to direct current (DC), which is used to charge batteries and power inverters.
     Battery: Stores electrical energy as a backup when the mains power is interrupted.
     Inverter: Converts DC power into AC power to provide stable power output for load equipment.
     Static bypass: ensures the continuity of power supply in the event of internal failure or maintenance of the UPS system.

                

 

2. Common causes of UPS failures and professional suggestions

     Battery failure:
         Cause analysis: lack of regular maintenance, battery aging, inappropriate ambient temperature, charging problems (excessive or insufficient).
         Professional advice:
             Regularly perform maintenance and inspection on the battery, including testing of voltage, internal resistance, capacity and other parameters.
             Follow the battery manufacturer's recommendations to ensure the battery is operating at the appropriate ambient temperature.
             Use smart charging technology to avoid overcharging or undercharging.

 

     Inverter failure:
         Cause analysis: inverter overload, aging components, and poor heat dissipation.
         Professional advice:
             Monitor the load condition of the UPS system to avoid overloading the inverter.
             Regularly clean the heat dissipation holes and fans of the UPS system to ensure good heat dissipation.
             When selecting a UPS system, consider redundant design and hot backup solutions to improve system reliability.

     Capacitor failure:
         Cause analysis: capacitor aging, overvoltage, overcurrent.
         Professional advice:
             Choose high-quality capacitors and check their working condition regularly.
             Install capacitor protection devices, such as fuses, thermistors, etc., to prevent the spread of faults caused by damaged capacitors.

 

 

3. Professional action steps to ensure UPS reliability

     Develop a detailed maintenance plan:
         Including regular inspections, preventive maintenance, emergency troubleshooting, etc.
         Follow the manufacturer's maintenance guidelines to ensure your UPS system is in optimal working order.
     Implement environmental control strategies:
         Monitor the temperature and humidity of the environment where the UPS system is located to ensure that they are within the appropriate range.
         Use air conditioners, humidifiers and other equipment to adjust environmental parameters to meet the requirements of the UPS system.
     Strengthen employee training:
         Improve employees' awareness of the importance of UPS systems and train them on how to correctly operate and maintain UPS systems.
         Regularly organize training activities to update employees' understanding of new technologies and knowledge about the UPS system.
     Introducing intelligent monitoring technology:
         Use intelligent battery monitoring systems such as AceVig BMS to monitor the operating status and battery performance of the UPS system in real time.
         Through data analysis, potential failures can be predicted and measures taken in advance to reduce the risk of UPS system failure.

 

 

4. Conclusion

By taking the professionally recommended action steps above, you can significantly improve the reliability and longevity of your UPS system. At the same time, the introduction of intelligent monitoring technology can help enterprises promptly discover and solve UPS system failures and ensure the continuous operation of key equipment and services. Therefore, it is crucial for any business that relies on UPS systems to understand the common causes of UPS failures and take professionally recommended solutions.
