Offline UPS Systems

Offline UPS systems use the power from the mains in usual operation rather than using a built-in inverter which would help to clean the output power and supply a more consistent flow of energy. With offline UPS these should mainly only be used for home or small office use where you are only backing up a couple of machines. For larger operations and critical loads, you will want to go with a Line Interactive or On-line UPS.

If you have any questions or would like to find out further information about our offline UPS systems, get in touch with us today to speak to our specialist team.

We only have suppliers who meet our supply chain standards for quality (ISO 9001), health and safety (ISO 18001), and environmental management (ISO 14001).
