This blog explores the features, benefits, and practical applications of the SURT20KRMXLI, providing insights for IT professionals, facility managers, and businesses seeking enterprise-grade power solutions.
What is the APC Smart-UPS RT 20kVA RM 230V (SURT20KRMXLI)?
The SURT20KRMXLI is a rack-mountable, double-conversion online UPS with a capacity of 20kVA/16kW, operating at 230V (configurable for 220V or 240V) or 400V 3-phase input. Housed in a 12U rack form factor, it provides pure sine wave output, zero transfer time, and extended runtime options, making it ideal for environments requiring high availability. With an integrated Network Management Card and compatibility with PowerChute software, it offers advanced remote monitoring and graceful shutdown capabilities.
Key Features of the SURT20KRMXLI
- Double-Conversion Online Topology
The SURT20KRMXLI uses double-conversion technology, providing continuous power conditioning and zero transfer time during outages. This ensures seamless operation for sensitive equipment, protecting against surges, spikes, and voltage fluctuations. Its pure sine wave output is compatible with power-hungry blade servers and active PFC equipment. - High Power Capacity and Efficiency
With a 16kW/20kVA output, the UPS supports heavily loaded racks. It achieves 94% efficiency at full and half load, reducing energy costs and heat output. An internal bypass (automatic and manual) and optional external bypass enhance reliability during maintenance. - Flexible Input/Output Configurations
The UPS supports single-phase (230V) or three-phase (400V) input wiring, with a removable input/output wiring tray for easy installation by a professional electrician. Output connections include 8x IEC 320 C19 outlets, 2x IEC jumpers, and hardwired options (3-wire or 5-wire), offering versatility for diverse setups. - Extended Runtime Options
Equipped with four RBC44 battery modules (maintenance-free, sealed lead-acid), the SURT20KRMXLI provides approximately 4 minutes at full load (16kW), 8 minutes at 12kW, and 15 minutes at 8kW. Additional battery packs (e.g., SURT192RMXLBP2) can extend runtime to hours, ideal for critical applications requiring prolonged backup. - Integrated Network Management Card
The included Web/SNMP Management Card enables remote monitoring and control via a network. Administrators can access real-time UPS status, configure settings, and receive alerts through a web browser, SNMP, or APC’s InfraStruXure Manager. This feature is standard for models above 5kVA, enhancing manageability in distributed environments. - LCD Touchscreen Display
The color LCD touchscreen provides an intuitive interface for monitoring system parameters (e.g., load, battery status, input/output voltage) and alarms. LED status indicators and audible alarms further simplify diagnostics. - PowerChute Management Software
The included PowerChute Network Shutdown software ensures unattended, graceful shutdown of network operating systems, protecting data integrity during extended outages. It supports integration with virtualization platforms like VMware and Hyper-V. - Dual Mains Input
The UPS supports two separate power sources, increasing availability by allowing failover to an alternate source during power disruptions. This is critical for high-uptime environments like data centers. - Robust Battery Management
Features like temperature-compensated charging, hot-swappable batteries, and automatic self-tests prolong battery life (typically 3–5 years) and ensure early detection of issues. The nominal battery voltage is ±192V, with a discharge voltage of ±154V. - Green Premium Certification
The SURT20KRMXLI carries Schneider Electric’s Green Premium™ label, ensuring compliance with RoHS and other environmental regulations. It is designed for responsible disposal in the EU, minimizing environmental impact.
Benefits of the SURT20KRMXLI
1. Uncompromising Reliability
The double-conversion topology and dual mains input ensure continuous, clean power, making the SURT20KRMXLI ideal for environments where downtime is unacceptable. Its ability to handle wide input voltage ranges (160–280V) and low harmonic distortion (<5%) protects equipment in unstable power conditions.
2. Scalability and Flexibility
The UPS supports rack/tower convertible installation, protecting investments when transitioning environments. Extended runtime options and flexible wiring configurations make it adaptable to growing or changing infrastructure needs.
3. Simplified Management
The integrated Network Management Card and PowerChute software streamline remote monitoring and shutdown processes. Users report easy setup, with the LCD touchscreen and plug-and-play external batteries simplifying operation and maintenance.
4. Cost-Effective for High Loads
With high efficiency and support for power-intensive applications, the SURT20KRMXLI reduces operational costs compared to less efficient UPSs. Its ability to support blade servers and heavy racks makes it a cost-effective choice for enterprise environments.
5. Enterprise-Grade Support
APC offers a 2-year warranty and an Equipment Protection Policy (up to $150,000, region-dependent). Retailers like Critical Power Supplies provide 24/7 support, ensuring rapid response to issues.
