Liebert PSI5 UPS 1100 Vertiv 1,100 VA Pure Sine | Desktop UPS

Maintain uptime for sensitive desktop and edge equipment with the Liebert PSI5 UPS 1100. Built for clean power delivery, it provides pure sine wave output on battery to support active PFC power supplies and other electronics that prefer stable waveform quality over stepped approximation. With 1,100 VA / 660 W capacity, it gives administrators room to protect a workstation, network appliance, or small office system with more headroom than entry-level units. Two programmable outlets help tailor battery-backed coverage to the devices that matter most, while plug-and-play setup keeps deployment straightforward. The unit is designed for practical desktop use, making it a strong fit where space is limited but power quality cannot be compromised. For teams that value continuity, the PSI5 platform adds remote monitoring options and 5-year total coverage, helping reduce service interruptions and ownership friction. This model sits above basic backup units by focusing on waveform quality, outlet control, and long-term support. It is a measured choice for protecting critical endpoints that cannot tolerate abrupt shutdowns, data loss, or unstable power conditions.
