In environments where power reliability is non-negotiable—think data centers, industrial facilities, or critical IT infrastructure—a robust uninterruptible power supply (UPS) is a must. The APC Smart-UPS RT 20kVA RM 230V (SURT20KRMXLI), designed by Schneider Electric’s APC division, is a powerhouse in the UPS world, delivering high-density, double-conversion online power protection. This blog will unpack what the SURT20KRMXLI is, its key features, benefits, and why it’s a top-tier choice for demanding applications.
What is the APC Smart-UPS RT 20kVA RM 230V (SURT20KRMXLI)?
The APC Smart-UPS RT 20kVA RM 230V (SURT20KRMXLI) is a rack-mountable UPS with a 20kVA (16kW) capacity, engineered to provide continuous, clean power to mission-critical equipment. Part of the Smart-UPS RT (Real-Time) series, it features double-conversion online topology, ensuring zero transfer time to battery during outages and precise voltage regulation. The “RM” in its name stands for rack-mount, occupying 12U of space in a standard 19-inch rack, though it can also be used in tower form with the appropriate conversion kit.
Designed for 230V single-phase or 400V three-phase input environments (configurable), this UPS is a versatile solution for medium to large-scale setups. It’s built to protect servers, networking gear, telecom systems, and industrial equipment from power disruptions, offering scalable runtime and advanced management capabilities.
