Description

APC by Schneider Electric SMX3KR2UNCX145 UPS

Overview

The APC by Schneider Electric SMX3KR2UNCX145 is a 2700W line-interactive Uninterruptible Power Supply designed for rack-mountable deployments. It provides clean sine wave power to sensitive electronics, ensuring operational continuity during power fluctuations or outages. This unit is suited for protecting critical IT infrastructure, network closets, or server racks where stable power is paramount. The 120V input and 100-127V output range accommodate standard US commercial power. Its 540 Joules surge energy rating offers protection against transient voltage spikes.

Compatibility

This UPS is designed to support standard 19-inch rack-mount equipment. It functions with a wide range of IT hardware that operates within its 120V input and 100-127V output specifications, including servers, network switches, and workstations. It is compatible with IT systems requiring a sine wave output for stable operation. The 15A maximum current draw must be considered when provisioning power circuits.

Installation Notes

The SMX3KR2UNCX145 requires a standard 120V, 15A NEMA 5-15P input connection. It is designed for rack installation using standard rack rails (not included). Ensure adequate ventilation around the unit, as it generates up to 55 dB of noise during operation. The unit features an Emergency Power Off (EPO) port for immediate shutdown in critical situations. The detachable power cord is not a feature of this model.
