Eaton 9PXEBM48RT‑L – UPS Battery Module 48 V 1U

Overview

The Eaton 9PXEBM48RT‑L is a rack/tower extended battery module (EBM) engineered to increase runtime for compatible Eaton 9PX lithium‑ion UPS systems. It is deployed by IT infrastructure and data center engineers where backup duration must be extended beyond the internal UPS battery capacity. The module scales runtime without oversizing the UPS itself.

This EBM delivers 48 V DC battery output and uses lithium‑ion chemistry with integrated battery management for temperature regulation and lifecycle monitoring. Modules can be daisy‑chained up to four units to tailor runtime for critical loads. It connects to the host UPS via heavy‑gauge 48 V DC connectors designed for high‑current installation.

The form factor is 1U, suitable for standard 19‑inch rack deployment, and includes rack/tower mounting hardware. Its height and rail kit support installation in dense rack environments common to enterprise and edge data centers where space efficiency and modular battery scaling are required.

Integration is native with Eaton 9PX 1500 VA class UPS platforms (including 9PX1500RT‑L, 9PX1500RTN‑L, and 9PX1500GRT‑L). When connected, the UPS subsystem recognizes the EBM, coordinating battery charging and runtime reporting without manual override.

In practical deployment, the module is installed directly adjacent to or below the UPS, connected via the provided cable. Multiple modules can be sequenced to reach required backup durations for systems such as virtualization hosts, networking gear, or storage arrays that require extended offline support before graceful shutdown.

This EBM should not be deployed standalone and requires a compatible 9PX UPS. It is not intended for use with non‑9PX platforms, nor is it suitable where only short, internal UPS runtime is needed, as internal batteries alone would suffice.
