The SURT15KRMXLI is built for high-power environments requiring clean, uninterrupted power, with a focus on scalability, reliability, and advanced management.
Key Features
1. Double Conversion Online Topology
The SURT15KRMXLI uses double-conversion online technology, converting incoming AC power to DC and back to AC to deliver a pure sine wave output. This ensures zero transfer time to battery power during outages, protecting sensitive equipment from surges, spikes, and voltage fluctuations. It’s ideal for power-hungry blade servers, networking gear, and medical or industrial devices.
2. Scalable Runtime
The UPS supports extended runtime through external battery packs (e.g., SURT192RMXLBP2), enabling hours of backup power for critical systems. This scalability is crucial for data centers or industrial setups requiring prolonged operation during outages.
3. High Efficiency
With a 94% efficiency rating at full load, the SURT15KRMXLI minimizes energy waste, reducing operating costs. Its internal bypass (automatic and manual) allows utility power to supply loads during maintenance or faults, enhancing efficiency without compromising protection.
4. Advanced Management and Monitoring
The included Web/SNMP management card (AP9631) enables remote monitoring and management via serial, USB, or Ethernet. The multifunction LCD status and control console provides real-time data on power conditions, load, battery status, and alarms. PowerChute software supports graceful shutdowns of connected systems during extended outages.
5. Hot-Swappable Batteries
The UPS features hot-swappable batteries (4 modules, APCRBC140), allowing replacement without powering down equipment. Automatic self-tests and temperature-compensated charging ensure battery reliability, with an expected life of 3–5 years.
6. Versatile Connectivity
With 8 IEC C19 outlets, 2 IEC jumpers, and a hardwire 3-wire option, the UPS supports a wide range of high-power devices. The SmartSlot allows customization with management cards, and the Emergency Power Off (EPO) feature enhances safety in critical environments.
7. Rack/Tower Convertible Design
The SURT15KRMXLI is a 12U rackmount unit but can be used as a tower, offering flexibility for various setups. Its heavy-duty rail kit ensures secure installation in server racks, though its 247.73 kg weight requires robust rack support.
Performance and Real-World Use
In real-world applications, the APC Smart-UPS RT 15kVA excels at protecting high-density loads in data centers, enterprise IT environments, and light industrial settings. At a 5,000W load (typical for server racks), it provides around 30 minutes of runtime, sufficient for safe shutdowns or bridging short outages. External battery packs can extend runtime significantly for prolonged outages.
The double-conversion topology ensures seamless power delivery, making it compatible with sensitive equipment requiring pure sine wave output, such as servers with active power factor correction (PFC) power supplies. Users report reliable performance in environments with unstable power, with the UPS effectively handling voltage irregularities and surges. For example, reviews from CDW.com highlight its “rock-solid” reliability, with no issues over five years except for occasional battery replacements.
The LCD console and network management card simplify monitoring, providing proactive alerts for battery maintenance. However, the 50 dBA noise level may be noticeable in quiet environments, and the unit’s significant weight and size require careful planning for installation and maintenance.
