Liebert Battery Cabinet for PSI5 UPS

This 24 V DC battery cabinet extends runtime for compatible Liebert UPS units. It is designed for server rooms and network closets that need additional backup power. The cabinet integrates directly with the PSI5-800RT120 and PSI5-1100RT120 models. Installation adds external battery capacity to the existing UPS system.

24 V DC output voltage

The cabinet delivers a fixed 24 V DC output that must match the UPS input requirement exactly. This single electrical specification determines whether the unit will function with your equipment. Verify that your UPS model is listed as PSI5-800RT120 or PSI5-1100RT120 before purchase. An incorrect voltage will prevent operation and may cause damage.

Extended runtime for PSI5-800RT120

The cabinet provides additional battery capacity for the listed 800 VA and 1100 VA UPS models during utility outages. It supports critical loads connected to these specific units until mains power returns or graceful shutdown completes. Runtime scales with the connected load and the UPS internal battery condition. The cabinet does not support other UPS models or voltage requirements.

Questions about this item

What does the 24 V DC output mean for my PSI5 UPS?

It matches the external battery bus voltage required by the PSI5-800RT120 and PSI5-1100RT120 so the cabinet connects directly without extra converters.

Which connection standard does the cabinet use to link with the UPS?

The cabinet uses the Liebert proprietary DC battery interface that keys to the PSI5-800RT120 and PSI5-1100RT120 rear-panel battery port.

What physical space does the cabinet need beside the UPS?

The cabinet is a separate enclosure designed to sit on the floor or shelf next to the PSI5-800RT120 or PSI5-1100RT120 and connects with the supplied DC cable.
