APC Smart-UPS RT 20000VA Tower/Rack Mountable UPS

In today’s data-driven landscape, uninterrupted power is not a luxury—it’s a foundation. The APC Smart-UPS RT 20000VA Tower/Rack Mountable UPS delivers high-density, online double-conversion power protection with scalable runtime designed to safeguard voltage-sensitive equipment and mission-critical workloads. With a zero-transfer-time transition to battery, it ensures continuous operation for servers, storage systems, networking devices, telecom gear, and vital office infrastructure. This UPS is engineered to protect your compute and communication environments from outages, surges, sags, and harmonic distortions while maintaining clean, robust power delivery. The 20 kVA class footprint accommodates substantial loads, and the 16 kW maximum load capacity provides ample headroom for expanding IT environments. Its flexible form factor — tower or rack-mountable — makes it ideal for data centers, server rooms, enterprise IT closets, and hybrid cloud setups where space, reliability, and uptime are non-negotiable. When uptime matters, the APC Smart-UPS RT 20000VA is designed to deliver reliable power protection with scalable runtime and intelligent management features that streamline operations, reduce risk, and protect your digital assets.

• Zero transfer time with online double-conversion topology: The UPS continuously converts incoming AC to DC and back to a clean, precise AC waveform, guaranteeing uninterrupted power to critical equipment and preserving data integrity even during grid disturbances or outages.
• High-density 16 kW (20 kVA) capacity with scalable runtime: This Smart-UPS RT supports demanding workloads—racks of servers, virtualization hosts, storage arrays, and network infrastructure—while offering scalable runtime through external battery cabinets to match maintenance windows and service-level objectives.
• Flexible deployment and rugged design: Install as a tower for versatile space planning or convert to a rack-mount configuration to fit standard 19-inch rack spaces. The design includes hot-swappable batteries and a sturdy chassis built to withstand demanding environments in data centers, telecom rooms, and manufacturing facilities.
• Advanced management and intelligent monitoring: A user-friendly LCD interface, along with USB and serial communication options, enables real-time monitoring and configuration. Optional Network Management Card support provides SNMP-based remote monitoring, email alerts, and seamless integration with IT management software for centralized control and automated graceful shutdowns.
• Built-in protection features and efficiency: Automatic voltage regulation (AVR) keeps output within tight tolerances, reducing wear on connected equipment. Comprehensive surge protection, maintenance bypass, and thermal/overload safeguards contribute to uptime and safety while helping keep energy use and cooling demands in check.

how to install APC Smart-UPS RT 20000VA Tower/Rack Mountable UPS

Preparing your installation begins with a location that supports reliable operation, easy service access, and proper ventilation. Choose a cool, dry space away from heat sources and direct sunlight. For rack deployment, mount the UPS in a standard 19-inch rack using the appropriate rails or cabinet configuration, ensuring stable mounting and adequate clearance for airflow and cable management. If you prefer a tower orientation, place the unit on a sturdy, level surface with at least several inches of clearance on all sides to promote cooling and service access. Ensure a dedicated circuit or appropriately rated branch circuit to support the UPS input and any charging loads. Plan cable routing so that critical devices are connected to the UPS output, and reserve space for network management connectors if you intend to use a Network Management Card for remote monitoring. Install External Battery Modules if you need extended runtimes; these EBMs can be hot-swapped in many configurations, minimizing downtime during maintenance. Connect communication interfaces (USB and Serial) to your management workstation or server to enable local monitoring and orderly shutdown procedures. If you opt for remote management, install the Network Management Card and configure SNMP settings, email alerts, and integration with your existing IT service management tools. Power up the unit and run a self-test to verify battery health and load performance. Configure input/output voltage, frequency, alert thresholds, notification schedules, and shutdown policies within the LCD interface or through your management software. Finally, document the installation with load calculations, runtime expectations, and a maintenance calendar to ensure consistent protection over time.
