Frequently Asked Questions
How does a line-interactive UPS work?
A line-interactive UPS works across a wide input voltage range. When the mains fails, the inverter engages instantly and the load keeps running from the batteries without interruption.
Which devices is a line-interactive UPS suitable for?
It is an economical solution for less critical loads such as computers, network and office equipment. For very sensitive loads that cannot tolerate any interruption, an online UPS should be considered.
Can extra batteries be connected to the LI Series?
No. The LI Series has a fixed battery runtime and does not allow extra batteries to be connected. If you need a longer backup time, a different UPS solution should be considered.
What should I consider when choosing a UPS?
The power of the load to be protected (VA/W), the required backup time, the input and output phase configuration, the installation environment and communication needs are assessed together. If you share your load details, we can help you choose the right model.
