APC SURTD6000RMXLP3U

Overview

The APC SURTD6000RMXLP3U is a rack-mount uninterruptible power supply designed to provide continuous, conditioned power to critical systems in a compact 3U form factor. Delivering up to 6000 VA (4200 watts) through true online double conversion, it ensures connected equipment receives a clean sine wave output at all times. This UPS is ideal for protecting servers, storage arrays, and sensitive lab instruments from power interruptions and electrical noise.

Its versatile outlet configuration supports both standard 120-volt devices and higher-voltage or split-phase equipment, making it suitable for mixed-voltage racks, edge data centers, and medical environments. The unit also features hot-swappable batteries and an integrated network management card for remote monitoring and control, ensuring reliable operation and easy maintenance.

Key features

• Online double conversion technology delivers consistent, clean power output free from distortion and noise
• Compact 3U rack-mount design fits standard equipment racks without occupying excessive space
• Outlet variety includes four NEMA 5-20R for 120 V devices, plus one NEMA L6-30R and one NEMA L14-30R for higher-voltage or split-phase loads
• Supports 208 or 240-volt input while providing 120-volt output, accommodating split-phase power setups
• Hot-swappable lead-acid battery modules allow battery replacement without shutting down connected equipment
• Integrated network management card enables remote status monitoring, self-tests, and graceful shutdowns via any web browser
• Cold-start capability powers connected devices directly from the battery bank when utility power is unavailable

Connectivity and compatibility

This UPS supports a range of devices thanks to its mixed outlet types and voltage compatibility. The four NEMA 5-20R outlets provide standard 120-volt power for typical IT equipment, while the L6-30R and L14-30R outlets accommodate higher-voltage or split-phase devices often found in data centers or specialized environments. The integrated network management card allows IT administrators to monitor and manage the UPS remotely, making it easier to maintain uptime and respond quickly to power events.

Performance and reliability

With true online double conversion, the UPS continuously regenerates clean power, protecting sensitive electronics from voltage fluctuations, noise, and distortion. The automatic bypass feature ensures connected loads remain powered during overloads or maintenance. Hot-swappable batteries minimize downtime by allowing battery replacement without interrupting power. The intelligent battery management system extends battery life by optimizing charge cycles, while the cold-start function provides emergency power when utility power is lost.

Ideal uses and environments

This UPS is well suited to small data centers, branch offices, and research labs where continuous power is critical. Its ability to handle mixed-voltage loads and provide clean, stable power makes it a strong choice for environments combining IT equipment with sensitive diagnostic or lab instruments. The compact 3U design fits neatly into standard racks, saving space while delivering robust power protection.

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.
