APC AP4452

Overview

The APC AP4452 is a rack auto transfer switch designed to maintain continuous power to single-corded equipment by automatically switching to a secondary power source if the primary feed fails. It fits into just 1U of rack space and supports up to 1920 VA at 120 V, making it suitable for servers, storage arrays, network devices, and lab instruments that require uninterrupted operation. The transfer between power sources occurs in less than 10 milliseconds, ensuring connected devices experience no noticeable downtime.

Key features

• Compact 1U rack design that saves valuable space in crowded data center racks
• Automatic transfer between two independent power sources to prevent downtime
• Ten NEMA 5-20R outlets to power multiple single-corded devices simultaneously
• Two eight-foot input cords with NEMA L5-20P plugs for reliable connection to separate power feeds
• Fast transfer time under 10 milliseconds to maintain continuous operation of sensitive equipment
• Front color LCD panel providing real-time voltage, current, and status information for easy local monitoring
• Integrated 10/100 RJ45 and serial ports enable remote monitoring, alerts, and firmware updates through standard network management tools
• Operates reliably in a wide temperature range from -5 to 45°C and at altitudes up to 10,000 feet
• Supports both 50 Hz and 60 Hz frequencies with a maximum input current of 20 A
• Constructed to meet RoHS environmental compliance standards

Connectivity and compatibility

The AP4452 connects easily to existing power infrastructure using its two NEMA L5-20P input cords, allowing it to draw from separate power sources for redundancy. Its ten NEMA 5-20R outlets provide ample capacity for multiple devices that rely on a single power cord. The integrated network and serial ports support remote management, making it compatible with standard network monitoring platforms for alerting and firmware updates. This makes it a practical choice for data centers, branch offices, and remote sites where reliable power and remote oversight are essential.

Ideal uses and environments

This transfer switch is well suited to environments where maintaining power continuity is critical but equipment only has a single power supply. It fits neatly into 1U rack space, making it a strong option for data centers with limited room. Its ability to operate across a broad temperature range and at high altitudes means it can be deployed in diverse locations, from controlled server rooms to remote branch offices. IT administrators looking to add redundancy without complex rewiring will find this unit straightforward and dependable.

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.
