Eaton SMART750RM1UN – 750VA Rackmount UPS 1U 120V

Overview

The Eaton SMART750RM1UN is a 750 VA / 500 W line-interactive rackmount UPS designed to provide battery backup and voltage regulation for rack-mounted IT and network equipment. It is deployed by network engineers and IT administrators in IDF/MDF closets and small rack environments to maintain uptime for switches, routers, and entry-level servers during power disturbances.

The unit operates on a 120 V single-phase power system and delivers output through six NEMA 5-15R outlets, supporting a mix of critical and non-critical loads. It incorporates automatic voltage regulation (AVR) to correct undervoltage and overvoltage conditions without switching to battery, preserving battery life. The system provides pure sine wave output when on battery, ensuring compatibility with active PFC power supplies.

Physically, the SMART750RM1UN is built in a compact 1U rackmount form factor, designed for installation in 19-inch EIA-standard racks. Its shallow depth allows deployment in wall-mount racks or network cabinets with limited space. The front-panel LCD provides real-time visibility into load level, battery status, and input/output conditions.

Integration includes USB and serial communication ports for local management and shutdown signaling, along with a network card slot for optional remote monitoring via Eaton’s network management platforms. The UPS integrates into rack power architectures where a PDU distributes protected output to connected devices.

A typical deployment involves protecting a network rack with switches, firewalls, and edge compute devices, ensuring continuity during short outages and voltage instability. This unit is not suitable for high-density server environments or loads exceeding 500 W, nor for applications requiring extended runtime without additional external battery modules.
