APC SMTL750RM2UCNC Smart‑UPS Li‑Ion 750VA Short‑Depth Rack/Tower UPS

Overview

The APC SMTL750RM2UCNC is a line‑interactive rack/tower UPS designed to provide regulated backup power and surge protection for small server racks, edge computing nodes, network infrastructure, and IT closets where rack depth is constrained. It is typically deployed by network architects, systems engineers, and infrastructure administrators who require compact UPS protection with remote management capabilities in distributed environments.

This UPS delivers 750VA / 600W capacity with pure sine wave output, compatible with modern servers, network appliances, and active‑PFC devices. Its Automatic Voltage Regulation (AVR) topology corrects undervoltage and overvoltage conditions without immediately switching to battery mode, reducing unnecessary battery use and maintaining stable output for connected loads. The system operates on 120V AC single‑phase power and uses a NEMA 5‑15P input.

The unit features a short‑depth 2U rackmount chassis, providing extra space for cable management in shallow racks and telecom cabinets. It also supports tower convertible deployment with optional stabilizing feet, making it flexible for both rack‑mounted and freestanding installations. Six NEMA 5‑15R battery‑backup outlets support connected devices without overloading typical small‑rack loads.

Management and monitoring capabilities are provided through a preinstalled Network Management Card and SmartConnect remote monitoring, enabling cloud‑based status tracking, firmware updates, and proactive alerts via APC EcoStruxure IT or third‑party monitoring platforms. The UPS also supports graceful server shutdown via PowerChute Network Shutdown for physical and virtual systems.

In practical deployments, the SMTL750RM2UCNC protects edge compute devices, router and switch stacks, and small storage systems in IDF/MDF closets or back‑office racks. With a roughly 5.7‑minute runtime at full load and longer at reduced loads, it provides enough time for clean shutdowns or generator failover in short outages.

This device is not suitable for high‑density rack servers or long runtime requirements. Its 600W limit and compact form factor make it designed for modest IT loads rather than multi‑server data center racks.
