APC Smart-UPS SRT1500RMXLA 1500VA Sinewave RM 2U 120V

Product Overview

The APC Smart-UPS SRT1500RMXLA is a 1500VA / 1350W double-conversion on-line UPS in a 2U rackmount chassis, providing zero-transfer-time battery backup with pure sine wave output and scalable runtime for commercial AV and IT rack deployments requiring the highest level of power protection. Unlike line-interactive UPS units, the SRT1500RMXLA operates in continuous double-conversion mode, delivering consistently clean, regulated power regardless of input conditions — essential for sensitive AV processing equipment, servers, and medical-grade electronics in commercial environments. SmartSlot expansion accepts optional network management cards for enterprise SNMP monitoring.

Product Description

Double-conversion on-line topology means the SRT1500RMXLA isolates connected equipment entirely from the input power source, regenerating clean power on the output at all times. This eliminates transfer time during power events, providing seamless protection for AV over IP systems, digital signage servers, and high-sensitivity AV processing equipment where even the brief switching delay of line-interactive UPS units may cause disruption. The 2U rackmount chassis installs in standard 19-inch racks and ships with rail kit hardware. Extended runtime is achievable by connecting compatible APC SRT external battery packs, making this unit appropriate for commercial AV systems with extended runtime requirements. The SmartSlot accepts APC network management cards for SNMP integration. A wide input voltage window reduces battery use during voltage fluctuations, and the unit includes a high-efficiency mode for reduced energy consumption in commercial deployments.

Frequently Asked Questions

What is the difference between double-conversion on-line and line-interactive UPS?

A double-conversion on-line UPS continuously converts AC to DC and back to AC, delivering consistently clean power with zero transfer time during outages. A line-interactive UPS uses the incoming AC directly during normal operation and switches to battery during outages, resulting in a brief transfer time (typically 2–4ms). For sensitive AV processing and servers, double-conversion is the preferred topology.

Does the SRT1500RMXLA include an NMC?

No. An optional APC network management card must be installed in the SmartSlot for SNMP and enterprise monitoring. The SRT1500RMXLA-NC model includes a pre-installed NMC. See the SRT1500RMXLA-NC listing on creationnetworks.net.

How do I extend runtime for a critical AV load?

Connect an APC SRT external battery pack (such as the SRT48RMBP or SRT72BP) to the SRT1500RMXLA. Multiple packs can be connected for extended runtime. Contact Creation Networks for runtime sizing.

Is installation in a commercial AV rack straightforward?

Yes. The included rail kit hardware supports installation in standard 19-inch racks. The 2U chassis occupies minimal rack space for the capacity provided.
