Overview of the APC Smart-UPS RT 15kVA RM 230V
The SURT15KRMXLI is part of APC’s Smart-UPS On-Line series, offering a 15kVA/12kW power capacity with double-conversion online topology. This ensures zero transfer time during power disruptions, delivering clean, stable power for sensitive equipment. Its 12U rack-mountable design, convertible to a tower configuration, provides flexibility for various setups. With advanced management features, scalable runtime, and high efficiency, the SURT15KRMXLI is tailored for environments like small to medium data centers, voice/data networks, medical labs, and light industrial applications.
Key Features of the SURT15KRMXLI
1. Double-Conversion Online Topology
The SURT15KRMXLI employs double-conversion technology, converting incoming AC power to DC and back to AC for a pure sine wave output. This eliminates power disturbances such as surges, spikes, and voltage fluctuations, ensuring zero transfer time to battery during outages. It maintains less than 5% output voltage distortion and a 3:1 crest factor, making it compatible with active power factor corrected (PFC) power supplies.
2. High Power Capacity
With a 15kVA/12kW output capacity, the UPS supports high-power loads, ideal for blade servers, networking equipment, and heavy equipment racks. It offers a nominal output voltage of 230V, configurable for 220V or 240V, and supports single-phase or three-phase input (230V or 400V 3PH). Output connections include 1x Hard Wire 3-wire (H N + G), 1x Hard Wire 5-wire (3PH + N + G), 8x IEC 320 C19, and 2x IEC Jumpers.
3. Scalable Runtime
The UPS supports extended runtime through additional external battery packs (e.g., SURT192RMXLBP2), allowing businesses to customize backup duration from minutes to hours. It includes four battery modules with a nominal voltage of ±192V, using maintenance-free, sealed lead-acid batteries with suspended electrolyte. The typical recharge time is 2.5 hours, and hot-swappable batteries enable replacements without powering down.
4. Advanced Management and Monitoring
The SURT15KRMXLI comes with a pre-installed Web/SNMP Management Card (AP9631) for network-based monitoring and integration with APC’s InfraStruxure Manager or third-party systems. PowerChute Network Shutdown software ensures graceful shutdowns of servers and virtual machines. The multifunction LCD display provides an alpha-numeric interface for real-time system parameters, alarms, and configuration. Connectivity options include DB-9 RS-232, RJ-45 10/100 Base-T, and Smart-Slot interfaces.
5. High Efficiency
The UPS achieves 94% efficiency at full and half load, reducing energy costs. It features an automatic internal bypass (static and manual) and an optional external bypass to maintain power during overloads or faults. Its input power factor of 0.95 minimizes harmonic distortion, ensuring efficient power utilization.
6. Flexible Design
The 12U rack-mountable design (533 mm H x 432 mm W x 773 mm D, 247.73 kg) is convertible to a tower configuration, protecting initial investments when transitioning environments. A removable input/output wiring tray simplifies installation and maintenance. The UPS supports dual mains input for increased availability, connecting to two separate power sources.
7. Intelligent Battery Management
APC’s intelligent battery management system maximizes battery life (3–5 years) through precision temperature-compensated charging and automatic self-tests. The replacement battery (APCRBC140) and four battery modules ensure reliable performance, with proactive notifications for battery replacement.
8. Robust Surge Protection
The UPS provides full-time multi-pole noise filtering with 0.3% IEEE surge let-through and zero clamping response time, meeting UL 1449 standards. This protects connected equipment from damaging surges, spikes, and lightning.
