Key Features & Benefits

• Extended Runtime Scaling: Combine up to 10 external battery packs to increase backup time on supported Smart-UPS X systems.
• 2U Rack/Tower Convertible: Deploy in a rack or upright tower orientation using the included mounting hardware/rail kit.
• 120Vdc Lead-Acid Design: Battery string designed for Smart-UPS X applications requiring additional energy storage.
• Enclosed Battery Cartridge: Device mounting as an enclosed cartridge streamlines integration with the UPS.
• Serviceable RBCs: Uses two APCRBC118 replacement battery cartridges; removable, user-replaceable design aids maintenance.

Technical Deep Dive

This external pack adds DC energy capacity to Smart-UPS X systems via a 120Vdc battery string composed of 10 blocks per string. By adding additional packs (up to ten total), the available energy for the connected UPS increases, supporting longer runtimes during outages.

The 2U rack/tower convertible construction, together with the supplied mounting brackets/rail kit, supports versatile installation in network rooms and equipment racks. The pack’s device mounting as an enclosed battery cartridge helps keep the battery assembly contained during install and service.

For ongoing serviceability, the unit uses two APCRBC118 replacement battery cartridges. Uses a removable, user-replaceable battery design, allowing swap-outs as needed without replacing the entire external pack.

Ideal Applications

• Smart-UPS X installations that require extended runtime
• Sites needing rack or tower deployment options in a 2U footprint
• Deployments planning to scale runtime by adding multiple packs (up to 10)
