UPS systems (uninterruptible power supplies) are essential for protecting critical IT and electronic systems from power failures and fluctuations. But not all UPS technologies are the same.
In this article, we take a look at the differences between line-interactive systems and online continuous converters and explain why multimatic relies on online continuous converter technology.
Line-interactive UPS systems offer protection against power failures and voltage fluctuations by automatically switching between mains power and battery operation. This technology is efficient as the mains power is passed directly to the load when there are no faults. The voltage is regulated by means of a voltage regulating transformer (AVR), which compensates for minor fluctuations.
Advantages of a line-interactive UPS:
Online continuous converter UPS systems, also known as double conversion technology, offer unparalleled protection. The mains current is completely converted into direct current and then transformed back into alternating current before it reaches the connected devices. This creates a complete separation between the mains current and consumers.

A key advantage of online continuous converter technology is its ability to completely eliminate typical mains interference - interference that could otherwise have a negative impact on sensitive IT and electronic systems. Thanks to continuous double conversion, it ensures a particularly stable and clean power supply that provides reliable protection even in the event of major fluctuations.
Line-interactive UPSs, on the other hand, only offer limited protection and quickly reach their limits in the event of more complex power problems. As they do not guarantee complete separation between the mains power and the connected devices, there is an increased risk, particularly for sensitive IT systems - for example, due to harmonic distortion or sudden voltage dips.
