A backup power system is used to provide energy when the primary source fails. This system is very important since an uninterruptible power supply is crucial for any operation.
What is the difference between a home long backup system and a UPS system?
A UPS system is designed to backup sensitive equipment like servers, computers, medical equipment, telecommunications equipment, etc. Standard UPS systems have small internal battery sets and can only provide short backup times of approximately 5 – 10 minutes which cannot be extended as the internal battery chargers are small and can only cater for the internal battery sets they were designed for. Additional or external batteries cannot be connected to these UPS systems.
There are also long backup UPS systems available which can be supplied with external battery sets to provide backup for, usually not more than 2 hours. If the user requires longer backup than 2 hours, the system would then have to be intentionally oversized to cater for the longer backup time, which can then be extended to 4 – 6 hours. For longer backup times, UPS systems should be installed in conjunction with a generator.
The double conversion online UPS systems have no break whatsoever and the sensitive equipment will always run on electronically produced power and is not directly connected to the mains power.
