Line Interactive UPS Systems

Line Interactive UPS is different from the offline in that Line Interactive UPS systems have an automatic voltage regulator that is used to correct an abnormal voltage without having to switch to the batteries. This causes wear and a reduced lifespan of the batteries meaning you have to replace them sooner. This feature also helps to protect and prolong your equipment lifespan due to getting a consistent and reliable voltage rate. If you are running equipment that will shut down within a few milliseconds if there is a power cut then you will be looking for our On-line UPS range.

View the exceptional line interactive UPS system below to find the right solution or contact us today if you require further advice on our products.

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