[PDF Version]An uninterruptible power supply, also known as UPS or battery backup, is an electrical device that provide power source to the load during the power outages. The UPS is mainly used to provide a stable and uninterrupted power supply to personal computers, peripherals, network system telecommunication equipmentor other power electronic equipment etc.
If your uninterruptible power supply is not working, the first and most obvious cause could be a battery issue. In a study performed by the Ponemon Institute, battery failure was classified as the leading cause of data centre outages. UPS Solutions offers a complimentary battery finder that locates the model of your choice within seconds.
What it is: When you notice that your UPS isn't working after a power outage, the first troubleshooting step you should take is to check its incoming power supply. Remember: the UPS will drain its battery during a power outage. If the outage goes on for too long, the UPS will lose all its power and must recharge when power is restored.
Ageing Power Supplies If your system regularly overheats, an ageing power supply can cause your UPS to fail. But troubleshooting an outdated power supply isn't as simple as other UPS problems. You need someone on call 24/7 to get you back up and running as quickly as possible.
When that happens, the UPS will not work after the power cut. How to fix it: One way to solve this issue is to disconnect the UPS from its wall socket and leave it alone for a few minutes. You can plug the UPS back into the wall socket when you're confident that the power cut is over and your power supply has become stable.
Uninterruptible power system (UPS) failures can spell disaster for businesses that rely on this form of backup power to prevent critical data loss. In fact, UPS system failure ranks as the No. 1 cause of unplanned data center outages, according to a report from the Ponemon Institute.
