Emerson PSI5 3000VA Lithium-Ion UPS

The Emerson Network Power PSI5 is a lithium-ion uninterruptible power supply rated at 3000VA and 2700W. It provides battery backup for servers and network equipment. The unit uses Vertiv branding and was first listed by the manufacturer on 22 September 2025. It is supplied in new condition.

Suits racks needing lightweight lithium runtime

This UPS suits administrators who want the reduced weight and longer cycle life of lithium-ion cells compared to lead-acid alternatives. It fits environments where 2700W output covers the connected load. Buyers needing extended runtime beyond the internal battery should consider external battery modules. Sites requiring lead-acid chemistry for regulatory reasons should evaluate other models.

2700W output capacity defines the load limit

The 2700W real-power rating is the single figure that determines which equipment this unit can support. Total connected devices must not exceed this wattage. The 3000VA apparent-power rating helps with sizing wiring and breakers. Confirm your load profile against the 2700W maximum before purchase.
