APC SMT750I

Overview

The APC SMT750I is a line interactive uninterruptible power supply (UPS) designed to provide 750 volt-amps (VA) and 500 watts of pure sine-wave backup power. It protects critical electronics from power outages, voltage sags, and surges, ensuring continuous operation for devices such as small business servers, networking equipment, and point-of-sale systems. The unit features Automatic Voltage Regulation (AVR) to correct voltage fluctuations without using battery power, extending battery life and maintaining stable voltage for connected devices.

Key features

• Line interactive design with Automatic Voltage Regulation to maintain safe voltage levels and reduce battery use during minor power fluctuations
• Six IEC C13 outlets and one IEC C14 input, with two jumper cables included for easy connection to devices using standard power connectors
• SmartSlot expansion bay supports an optional Network Management Card for remote monitoring and integration with management platforms
• Front-panel LCD provides real-time status updates and detailed information such as load, input voltage, and estimated runtime
• USB and serial ports enable connection to PowerChute software for automated shutdown and event logging
• 540-joule surge protection safeguards equipment from lightning strikes and utility power spikes
• User-replaceable sealed lead-acid battery simplifies maintenance and reduces downtime
• Two-year battery warranty and three-year chassis warranty with EcoStruxure and third-party monitoring compatibility

Connectivity and compatibility

This UPS fits well in environments where IEC C13 power connectors are standard, such as server rooms, network closets, and retail checkouts. The included jumper cables facilitate quick setup with existing equipment. USB and serial interfaces allow seamless integration with PowerChute software for graceful shutdowns and event tracking, while the SmartSlot expansion bay supports network management cards for remote control and monitoring.

Performance and reliability

The line interactive topology with Automatic Voltage Regulation ensures that connected devices receive stable power by correcting voltage dips and surges without immediately switching to battery power. This approach extends battery life and reduces wear. The pure sine-wave output supports sensitive electronics that require clean power, while the 540-joule surge protection guards against damaging spikes. The user-replaceable battery design minimizes downtime during maintenance.

Ideal uses and environments

The SMT750I is a strong choice for small businesses and branch offices that need reliable backup power for servers, edge networking gear, VoIP hardware, and lab equipment. It works well in retail environments to keep point-of-sale systems operational during outages and protects surveillance systems that require continuous uptime. Its compact tower design fits neatly into limited spaces such as network closets or IT racks.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
