Vertiv PSI5-3000SRT120LI Liebert PSI5 Series 3kVA 2700W Rack/Tower Lithium-Ion UPS with AVR and Pure Sinewave Output

Deliver reliable, clean backup power for critical IT and security equipment with the Vertiv Liebert PSI5 Series 3kVA UPS. Designed for server rooms, network closets and surveillance systems, this UPS provides 2700W of continuous output and lithium‑ion battery technology to reduce maintenance and extend service life compared with traditional batteries. Built‑in Automatic Voltage Regulation (AVR) and pure sinewave output protect sensitive devices—IP cameras, NVRs, access control panels, and networking gear—from voltage fluctuations and waveform distortion.

The Vertiv PSI5-3000SRT120LI's rack/tower convertible design lets you deploy in space‑constrained racks or as a standalone tower, while its compact footprint and high efficiency lower operating costs for 24/7 monitoring and security operations. IT managers and integrators benefit from dependable runtime and stable power conditioning that keep security, surveillance and monitoring systems online during outages and brownouts. Ideal for enterprise networking, physical security, and edge computing deployments—contact our sales team to configure runtime options and protect your critical infrastructure.
