A number of published comparisons indicate that DRUPS is a superior solution for data center cooling and IT applications. The inaccurate assumptions and mistakes found in these comparisons are explained with support from third party sources. In this paper, we present a detailed quantitative comparison from a design architecture-level perspective between low voltage DRUPS and low voltage Static UPS. We consider capital expenses, energy losses, maintenance costs, footprint, and TCO using a common 2N architecture. The analysis shows the Static UPS is less expensive to purchase, install, operate, and maintain while having a slightly larger footprint.
