Ideal for edge deployments

The Vertiv PSI5-800RT120N is a line-interactive UPS rated at 800VA and 720W, built for 120V environments. It protects active PFC power supplies, conventional power supplies, networking gear, workstations and point-of-sale systems in media closets or small racks. Six NEMA 5-15R outlets and a rotating LCD give clear status in either rack or tower orientation.

Upgrade from basic surge strips

This unit adds automatic voltage regulation across a 75-146VAC input window and pure battery backup with 5.5 minutes at full load or 16 minutes at half load. The jump is worthwhile when equipment needs orderly shutdown time or when voltage sags and swells exceed what a strip can absorb. It is not suited for loads that exceed 720W or for installations requiring extended runtime beyond the internal battery.

Simple 2U rack or tower setup

The 2U convertible chassis mounts in standard racks or sits as a tower with the display rotated. A hot-swappable battery cartridge (PSI5-24VBATT) reaches 90% charge in four hours. The only common pitfall is forgetting to configure the output voltage (100/110/115/125VAC) to match the connected gear before powering on.

Questions about this item

What rack depth does the 2U rack/tower chassis require for mounting?

The unit is a 2U rack/tower convertible design; allow standard 2U vertical space and ensure the rack depth accommodates the chassis length with clearance for rear cable connections.

How do I configure the output voltage to match my equipment?

Use the front-panel LCD menu to select 100, 110, 115, 120 or 125 VAC before connecting loads; the default is 120 VAC and the setting is retained after power cycles.

Which replacement battery kit restores runtime when the internal cells age?

Order the PSI5-24VBATT kit; recharge takes four hours to reach 90 % capacity and typical half-load runtime is 16 minutes with fresh batteries.
