Vertiv PSI5-500SRT1ULI 500VA 450W Lithium-Ion UPS 1U Rack/Tower

500VA 1U rack-tower UPS

The Vertiv PSI5-500SRT1ULI is a line-interactive uninterruptible power supply rated at 500VA and 450W. It fits a single rack unit or stands as a tower for IT equipment, server rooms and network closets. Four NEMA 5-15R outlets connect protected loads from a NEMA 5-15P input cord. Lithium-ion cells replace traditional lead-acid batteries for longer service life and faster recharge.

Hot-swappable lithium-ion battery and USB management

Internal lithium-ion modules recharge to full capacity in two hours and can be swapped without powering down connected gear. A USB port enables local monitoring and shutdown scripting, while an optional network card adds remote management. Programmable outlets let administrators shed non-critical loads during extended outages to preserve runtime for essential devices.

Verify 120V input and outlet count before ordering

The unit accepts 100 to 125VAC nominal input with a 75 to 150VAC operating window and auto-senses 50 or 60Hz frequency. Ensure your facility voltage matches this range and that four NEMA 5-15R receptacles suit your equipment plugs. Rack mounting requires a standard 1U opening; tower placement needs a stable surface within the 32 to 104°F operating temperature window.
