Key Features of the APC SURT15KRMXLI
1. Double-Conversion Online Topology
The SURT15KRMXLI employs double-conversion online technology, providing tight voltage and frequency regulation with zero transfer time to battery during power outages. This ensures clean, uninterrupted power for sensitive equipment, even in harsh power environments with frequent voltage fluctuations or generator use.
2. Scalable Runtime with External Battery Packs
The UPS supports extended runtime through additional battery packs (e.g., SURT192RMXLBP2), allowing businesses to meet aggressive runtime demands. This is particularly valuable for data centers or medical labs requiring hours of backup power rather than minutes.
3. Dual Mains Input
The dual mains input feature increases availability by allowing the UPS to connect to two separate power sources, providing redundancy and minimizing downtime in case of a primary power failure.
4. Intelligent Battery Management
APC’s intelligent battery management system maximizes battery performance and lifespan through precision temperature-compensated charging. Periodic self-tests detect battery issues early, and hot-swappable battery modules (APCRBC140) enable replacement without powering down connected equipment. Expected battery life is 3–5 years.
5. Advanced Management and Connectivity
- LCD Display: An alpha-numeric display provides real-time system parameters, alarms, and diagnostics for easy monitoring.
- Interface Ports: Includes DB-9 RS-232, RJ-45 10/100 Base-T, and a Smart-Slot for optional network management cards (e.g., AP9631, pre-installed).
- PowerChute Software: Enables safe system shutdowns, remote monitoring, and energy management via serial, USB, or Ethernet connections.
- Remote Management: Supports centralized management through APC’s InfraStruXure Manager or remote firmware updates via FTP.
6. Rack/Tower Convertible Design
The SURT15KRMXLI is rack/tower convertible, protecting your investment when transitioning from tower to rack-mount environments. Its removable input/output wiring tray simplifies installation and maintenance.
7. Robust Surge Protection and Power Conditioning
With full-time multi-pole noise filtering (0.3% IEEE surge let-through, zero clamping response time) and compliance with UL 1449, the UPS protects connected loads from surges, spikes, and lightning. Its double-conversion architecture minimizes noise and ensures compatibility with active power factor correction (PFC) power supplies.
8. Bypass Options
The UPS includes built-in static and internal bypass (automatic and manual) with an optional external bypass, ensuring continuous power delivery during maintenance or overload conditions.
Benefits of the APC SURT15KRMXLI
1. High Availability for Critical Systems
The double-conversion topology, dual mains input, and scalable runtime ensure maximum uptime for servers, voice/data networks, and medical or industrial equipment. This makes the SURT15KRMXLI ideal for environments where downtime is not an option.
2. Flexibility and Scalability
With configurable input/output voltages (220V, 230V, 240V) and support for single or three-phase wiring, the UPS adapts to diverse power environments. The ability to add external battery packs makes it suitable for applications requiring extended runtimes.
3. Energy Efficiency
The SURT15KRMXLI achieves 94% efficiency at full load and 93% in battery operation, reducing energy costs while maintaining high performance. Its eco-friendly design includes RoHS compliance and a minimum 70% recycled cardboard packaging.
4. Ease of Management
The multifunction LCD console, combined with PowerChute software and network management capabilities, simplifies UPS monitoring and control, reducing the need for on-site intervention.
5. Durability and Reliability
Built for harsh power environments, the SURT15KRMXLI offers robust surge protection, tight voltage regulation, and a proven track record from APC, with over 25 million Smart-UPS units sold globally.
Practical Considerations
Runtime
At full load (12kW), the SURT15KRMXLI provides approximately 8 minutes of runtime, which can be extended significantly with external battery packs. For example, adding one SURT192RMXLBP2 battery pack may increase runtime, though some users have reported issues achieving expected runtimes (e.g., 8 minutes instead of 23 minutes at full load with one additional pack). Always use APC’s UPS selector tool to calculate runtime for your specific load.
Weight and Space
Weighing 247.73kg and occupying 12U of rack space, the SURT15KRMXLI is a substantial unit, requiring careful planning for installation in data centers or server rooms. Ensure adequate rack space and structural support.
Noise Levels
The UPS produces audible noise (50.0dBA at 1 meter), which may be noticeable in quiet environments. Place it in a well-ventilated, noise-tolerant area.
Battery Maintenance
The hot-swappable APCRBC140 battery modules simplify maintenance, but with an expected lifespan of 3–5 years, budgeting for replacements is essential. Regular self-tests help identify battery issues early.
Installation and Setup
The SURT15KRMXLI includes:
- CD with PowerChute software
- Rack-mounting support rails
- Smart UPS signaling RS-232 cable
- User manual
- Web/SNMP management card
Installation involves connecting the UPS to a power source (single or three-phase), attaching devices to the output connectors, and configuring the system via the LCD console or PowerChute software. The removable wiring tray and rack-mount design streamline setup and maintenance.
