Eaton BP48V60RT3UTAA 48 V External UPS Battery Pack

Overview :

The Eaton BP48V60RT3UTAA is an external battery expansion module designed to significantly extend runtime on compatible high‑capacity UPS systems that employ a 48 V DC battery architecture. It is deployed by data center and facilities engineers alongside UPS units that support external racks of batteries where runtime beyond internal packs is required. This battery pack solves runtime deficiency under extended power outages, enabling orderly shutdowns or continued operation for critical loads.

This unit is rated for a 48 V DC system and is expandable via a daisy‑chain connector, allowing multiple packs to be connected in series with the host UPS to increase overall backup time. The pack includes a heavy‑gauge DC cabling harness and high‑current connectors that match the UPS battery terminals for simple and secure installation.

Physically, the BP48V60RT3UTAA occupies 3U of rack space and ships with mounting hardware for 4‑post rack installation; optional accessories extend support to 2‑post racks or upright tower placement. It is fabricated in a steel enclosure to meet robust mechanical integration requirements in server rooms, telco closets, and enterprise infrastructure spaces.

Integration is direct: the attached DC connector plugs into compatible Eaton/Tripp Lite UPS models specified in the battery pack’s compatibility list. The unit does not include AC output, UPS electronics, or power conversion — it functions strictly as an energy reservoir that the UPS inverter draws upon during utility outages.

A practical deployment example is pairing this pack with a SMART3000RMXL2U UPS to achieve extended runtime for rack servers and SAN storage during prolonged outages without upsizing the UPS unit itself. This model should not be used where the UPS in question does not support external battery shelves or in installations requiring integrated UPS bypass and maintenance features not provided by the battery alone.
