EATON EBM 5PX 72V RT2U Gen2

The Eaton EBM 5PX Gen2 external battery module directly extends the runtime of compatible Eaton 5PX Gen2 UPS units. This 72V module works in close cooperation with the main line-interactive unit, helping to maintain high system efficiency of up to 98%. It features a 2U design for flexible installation in a standard rack or for standalone vertical placement. The UPS automatically detects the module, simplifying the initial configuration and providing the system administrator with precise information about the total remaining backup time. This Eaton external battery module is an effective solution for applications requiring longer autonomy during a power outage, all while maintaining a compact size and easy management. This makes the Eaton EBM 5PX 72V RT2U Gen2 backup power supply suitable for protecting servers, network components and other IT infrastructure.

Installation flexibility and design

The module offers dual installation options for diverse IT environments. It is primarily designed for mounting in a data cabinet, where it occupies a standard 2U height. Its precise dimensions of 129×438×483mm are fully compatible with standard 482.6mm wide frames. The total weight of 39.7kg must be taken into account when planning the load capacity of the rack cabinet and its configuration. Alternatively, the module can be placed vertically next to the main UPS unit using a mounting plate, which is practical in office environments without a dedicated cabinet.

Battery and power configuration

At the heart of this module is an assembly of twelve maintenance-free lead-acid batteries, connected in series to provide a total nominal voltage of 72V, fully compatible with the main UPS unit. Each battery has a 12V/9Ah specification, which directly defines the module's total energy capacity and, consequently, the extension of the backup time. This assembly of twelve lead-acid batteries is designed for reliable, long-term operation in typical data centre conditions. The maintenance-free nature of the batteries reduces the need for servicing throughout their life cycle. As the accessory type is defined as a battery/accumulator, its sole function is to extend the backup time without directly affecting the power topology or the quality of the output voltage.

Performance

When paired with a compatible Eaton 5PX Gen2 UPS, the entire system operates with an efficiency of up to 98% at full load. This high value helps to reduce energy losses, resulting in lower heat generation and a reduction in electricity running costs. The quality of the supplied power is defined by the UPS, which achieves zero output voltage distortion under a linear load. This is a key parameter for powering sensitive electronics, servers, and network devices that require a clean and stable sine wave voltage for flawless operation.
