APC SMT750CUS

Overview

The APC SMT750CUS is a line interactive uninterruptible power supply (UPS) designed to provide 750 volt-amperes (VA) and 500 watts of backup power. It safeguards workstations, network switches, and point-of-sale systems by offering enough runtime to handle brief outages or perform safe shutdowns during longer power interruptions. Its tower form factor fits neatly under desks or in compact network closets, making it a practical choice for environments with limited space.

With automatic voltage regulation (AVR), this UPS stabilizes voltage fluctuations such as brownouts and surges without immediately switching to battery power, which helps extend battery life and maintain runtime. When battery power is needed, the unit delivers a pure sine wave output that closely replicates utility power, ensuring sensitive electronics continue to operate smoothly.

Key features

• Line interactive design with automatic voltage regulation to correct voltage dips and spikes without draining the battery
• Pure sine wave output that supports sensitive equipment by providing clean and stable power
• Six NEMA 5-15R outlets spaced to accommodate a variety of plugs and power bricks, allowing multiple devices to be protected simultaneously
• Front panel LCD that displays real-time information on load, battery status, and event history for easy monitoring
• SmartConnect port enabling remote management through APC’s secure cloud portal, including email alerts, diagnostics, and firmware updates
• SmartSlot expansion bay for adding network management cards to enhance control and monitoring capabilities
• User-replaceable lead acid battery designed for quick and simple maintenance, extending the UPS’s service life
• Built-in surge protection to guard connected equipment against lightning strikes and power spikes
• Energy Star certification to help reduce energy consumption and operating costs
• Comprehensive warranty coverage with three years on the UPS and two years on the battery for reliable support

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.
