Technical FAQs 4

What are the different types of uninterruptible power supplies (UPS)?

In the first part of this article on Uninterruptible Power Supplies (UPS), we looked at the two main types of units, rotary and static, along with what considerations need to be taken into account when selecting a suitable UPS system. Here, we continue our deep dive into UPSs, examining the run or hold-up time, battery types and sizing.

How long does an uninterruptible power supply last?

Like all other IT equipment, an uninterruptible power supply (UPS) has a finite lifespan. The average expected lifecycle of a UPS is eight-to-ten years. The batteries typically need to be replaced at least three times during that lifespan. Of course, once a UPS reaches the end of its lifespan, it should be replaced to mitigate downtime.

How does an uninterruptible power supply work?

The uninterruptible power supplies have e.g. an adjustable maximum buffer time to protect the battery and the unit protects the battery from going into a deep discharge. Draining the battery all the way down can damage it in a very short period of time, especially if this occurs multiple times.

How do you choose an uninterruptible power supply?

When choosing a uninterruptible power supply, IT teams can evaluate two criteria. One is the life of the unit itself – up to ten years. The second consideration is batteries. Every UPS unit has a battery, which as mentioned, must be replaced up to three times.
