The home lab, a constantly evolving domain, requires reliable power supply. UPS units are essential to protect your equipment from power outages or surges. In this comprehensive guide, we will help you choose between line-interactive and online UPS systems based on your specific home lab needs. We will examine their technical characteristics, purchase cost, maintenance cost, as well as the advantages and disadvantages for each type.
Why this choice matters
To understand the difference between a line-interactive and an online UPS, it is important to know how each one works. A line-interactive UPS switches directly from grid power to battery in case of total outages with protection against surges through separate transistors for each phase. It’s a compromise between price and efficiency suitable for small loads like NAS or basic servers. In contrast, an online UPS operates continuously with double conversion: it constantly converts AC to DC before reconverting it to AC to power your equipment. This method provides better quality of electrical supply and enhanced performance but is also more expensive.
Buying criteria
The selection of a UPS depends on several criteria: the UPS capacity (VA), runtime, sinewave purity rate, and additional features. We did not test these products ourselves: the figures on this page are indicative orders of magnitude that we have not verified; refer to the manufacturers’ spec sheets. The management software specific to each brand also matters, for its ease of use and effectiveness.
