The Vertiv™ Liebert® PSI5 Lithium-Ion UPS is a reliable power protection solution for critical IT setups, especially in remote or edge locations. Its lithium-ion batteries last 8–10 years—up to three times longer than traditional VRLA batteries—reducing the need for replacements and cutting costs on both batteries and labor. This results in up to 50% lower total cost of ownership when compared to traditional VLRA batteries. It features automatic voltage regulation (AVR) technology to help guard against power fluctuations and extend battery life, while delivering pure sine wave output in battery mode to protect sensitive equipment. With up to 20 minutes of runtime at half load and 9 minutes at full load, it offers more backup time than many competitors. The 2U-3U Rack/Tower models offer a rotating or gravity sensing LCD display for installation flexibility, providing instant system visibility, remote monitoring support, and delivers up to 98% or greater energy efficiency. Backed by a 5-year full warranty, it’s a low-maintenance, set-it-and-forget-it solution from Vertiv.
