This online, double-conversion UPS delivers 20,000 VA (20 kVA) of clean, continuous power and up to 18,000 watts of output, designed to safeguard servers, storage, networking gear, and telecom equipment in a rugged 12U rack or tower configuration. Built for performance and reliability, this unit supports complete N+1 redundancy for loads up to 10 kVA, offering exceptional availability for data centers and server rooms. With USB and DB9 management interfaces, a manual bypass for maintenance, and hot-swap battery capability, it minimizes downtime and simplifies ongoing protection in demanding environments that operate on 200–240V utility feeds. Whether you’re deploying in a high-density server rack, a telecom closet, or a mixed IT space, this 20kVA online UPS provides scalable, dependable power to keep critical systems online and responsive.
- Power protection you can rely on: An online, double-conversion topology continuously rectifies incoming AC power to DC and inverts it back to pristine AC power, isolating connected equipment from input disturbances. This results in stable voltage, clean frequency, and reliable uptime for essential servers, storage devices, virtualization platforms, and network infrastructure.
- N+1 reliability for uninterrupted operation: When operated at loads up to 10 kVA, the SU20KRTG delivers complete N+1 redundancy. This design helps ensure that a single component failure or maintenance event does not interrupt service, making it a strong choice for mission-critical environments where availability is a top priority.
- Flexible deployment in a 12U rack footprint: Engineered to fit standard 19-inch racks, the 12U enclosure optimizes space in data centers and server rooms while leaving room for cabling and future expansion. The unit can also be configured as a tower if space or layout requires, maintaining front-panel accessibility and serviceability for quick maintenance and battery swaps.
- Comprehensive management and connectivity: Local monitoring is enabled via USB and DB9 serial ports, providing compatibility with popular management software and monitoring tools. Front-panel indicators and logs deliver at-a-glance status, runtime estimates, and battery health information, empowering IT teams to plan maintenance, firmware updates, and shutdown policies with confidence.
- Maintenance-friendly design with hot-swap batteries and manual bypass: The UPS features hot-swappable battery modules and a dedicated manual bypass switch for safe, low-downtime maintenance. Technicians can service, upgrade, or replace components without interrupting power to protected equipment, while administrators continue to receive alerts and status updates during the process.

how to install Tripp Lite by Eaton UPS Smart Online 20000VA 18000W Rackmount 20kVA 200-240V USB DB9 Manual Bypass Switch Hot Swap 12U
- Plan your layout: Select a stable, well-ventilated location with adequate clearance for airflow, access to the front panel, and rear cabling. Ensure your rack or shelf supports the weight and size of a 12U unit plus connected peripherals.
- Mount the unit: Install the UPS in a standard 19-inch rack using the provided rails or mounting kit. Ensure the front panel remains accessible for status checks, battery tests, and routine maintenance. If a tower configuration is preferred, follow the manufacturer’s guidance to secure the unit on a stable surface with proper ventilation.
- Connect input power: Connect the UPS input to a dedicated 200–240 VAC power source that matches the unit’s specifications. Use a properly rated circuit and breakers to support the total load without tripping during peak power events.
- Route and connect loads: Plug critical devices (servers, storage arrays, switches, and essential telecom equipment) into the UPS output outlets or a compatible PDU. Avoid overloading beyond the 18 kW rated output and distribute heavy loads across the UPS as recommended.
- Configure communications and software: Attach USB and DB9 cables to a management station or server, and install any provided management software. Configure shutdown policies, alert thresholds, event logs, and battery test schedules to align with your change-management processes.
- Power-on and verify: Power up the UPS and verify that the front-panel indicators report normal operation. Run a guided battery test if available and ensure that monitored systems receive the expected runtime and alerts during simulated events.
- Document and train: Record configuration details, network settings, and maintenance procedures. Provide IT staff with quick-reference guides for handling bypass operations, battery swaps, and routine diagnostics to minimize downtime during outages or service events.
Frequently asked questions
- What does 20,000 VA mean for this UPS, and how does it relate to watts? The 20,000 VA rating represents apparent power capacity. Real-world output is typically up to 18,000 watts for compatible loads, depending on power factor and efficiency. This makes it suitable for protecting mid- to large-scale server rooms and data-center equipment with higher power requirements.
- Can this UPS be deployed in a rack or as a tower? Yes. The SU20KRTG is designed for flexible deployment in a standard 19-inch rack (12U) and can be configured as a tower if needed, allowing you to adapt to space constraints or evolving data-center layouts.
- What is N+1 redundancy, and why is it important? N+1 redundancy means the system includes an additional backup module to maintain operation if a component fails or during maintenance. For loads up to 10 kVA, this design helps ensure continuous availability of critical workloads and minimizes unplanned downtime.
- Does it support hot-swappable batteries? Yes. The battery modules are hot-swappable, enabling replacement or upgrading without powering down connected equipment, reducing maintenance-induced downtime.
- What management interfaces are included? The unit provides USB and DB9 serial interfaces for local management, along with front-panel indicators and logs. These enable monitoring, alerting, and integration with compatible IT management systems.
- What kind of environments is this UPS best suited for? It’s ideal for data centers, server rooms, telecom closets, and any critical IT space where clean, reliable power and high availability are essential to protect servers, virtualization platforms, and network infrastructure.
