Eaton 9PX 3000VA 208V Online Double-Conversion UPS — L6-20P, 8 C13, 2 C19 Outlets

Power reliability is a business critical requirement in today’s data centers, edge deployments, and IT rooms. The Eaton 9PX 3000VA 208V online double-conversion UPS delivers rock-solid protection for servers, storage, networking gear, and edge equipment by providing clean, uninterrupted power even during outages, brownouts, and power quality disturbances. Designed for 2U rack mounting or tower placement, this 3 kVA/3 kW unit combines high efficiency with intelligent battery management, flexible runtime options, and modern cybersecurity capabilities. With a dedicated L6-20P input, a generous outlet mix of eight IEC C13 and two IEC C19 sockets, and optional cybersecure network management, the 9PX is built to safeguard critical workloads while helping you optimize energy use and administration across hybrid environments.

• Premium power quality and reliability: The Eaton 9PX uses an online double-conversion topology to deliver a continuous, clean sine-wave output, isolating sensitive IT gear from utility irregularities. This topology ensures stable voltage, precise voltage regulation, and constant waveform integrity. Automatic voltage regulation (AVR) corrects minor grid sags and surges without discharging the battery, preserving runtime for longer outages and reducing wear on your equipment. The result is fewer unexpected reboots, safer data processing, and extended life for servers, virtualization hosts, and storage arrays in data centers, small-to-midsize IT rooms, and edge environments.
• Flexible deployment and power distribution: Built for both rack and tower configurations, the 9PX occupies only 2U of rack space while offering a practical outlet mix to support diverse devices. A rear L6-20P input cord feeds the UPS from a dedicated 20A circuit, while the front-and-rear outlet array hosts eight IEC C13 sockets and two IEC C19 sockets. This mix accommodates a mix of servers, switches, storage, and network devices, helping simplify cable management and reduce the need for multiple power strips. Because the output is 208V, you get efficient, straightforward integration with common data center infrastructure and edge deployments without unnecessary step-down equipment.
• Extended runtime and easy serviceability: For longer outages or planned maintenance windows, the 9PX supports optional Extended Run Modules (ERM) to extend runtime without replacing the UPS. The batteries are hot-swappable, enabling maintenance or replacement without powering down connected equipment. Built-in battery health monitoring and self-tests help you track aging and schedule replacements before a failure occurs. This combination gives you greater control over downtime, enabling more accurate protection planning for critical workloads while keeping operating costs predictable.
• Cybersecure network management (optional): In an era of increasing cyber risk, the Cybersecure Network Card Option provides secure remote management and monitoring. The network card supports secure authentication, encrypted communications, and SNMPv3 with role-based access to prevent unauthorized access to UPS configuration and power data. This makes the Eaton 9PX suitable for regulated environments, multi-tenant data centers, and organizations that require auditable, tamper-resistant power management data across distributed locations.
• Comprehensive monitoring and proactive management: The 9PX ships with an intuitive LCD interface and standard management ports (USB and RS-232) for local control and diagnostics. Eaton’s Intelligent Power Management (IPM) software integrates with servers and virtualization platforms to automate graceful shutdowns, centralize event logging, and provide real-time health data. With load and battery capacity indicators, you can plan maintenance windows, optimize energy usage in blended on-premises and cloud environments, and respond quickly to power events with clear, actionable insights.

how to install Eaton 9PX 3000VA 208V UPS

• Plan and prepare: Select a suitable 2U rack location with adequate clearance for airflow and access to the front panel display. Ensure the installation site meets environmental requirements (ventilation, temperature, and humidity) and has a dedicated 20A circuit for the input supply.
• Mount the unit: Install the UPS in a standard 19-inch rack or place it on a stable, level surface if used as a tower. Use the included rack ears and mounting hardware to secure the unit firmly and ensure the front panel remains accessible for status readings and maintenance.
• Connect power and loads: Connect the L6-20P input plug to the dedicated 20A circuit. Distribute critical devices to the 8 C13 outlets and mission-critical gear to the 2 C19 outlets, ensuring that the most load-sensitive equipment is plugged into powered outlets that can be managed by the UPS during a power event.
• Configure management interfaces: Attach the USB cable or RS-232 port to a management workstation. If you are using the optional Cybersecure Network Card, install it into the SmartSlot, then configure network settings and security credentials via the LCD or IPM software. Run the initial self-test to verify proper operation.
• Set runtime, alerts, and shutdown policies: Use the LCD interface or IPM software to set preferred shutdown thresholds, notification emails, and automatic shutdown rules for connected devices. For ERM-enabled deployments, install the Extended Run Module per the manufacturer’s instructions to extend runtime to your required maintenance or outage window.
• Verify operation: Power on the UPS, monitor the LCD for status indicators, and perform a simulated outage to confirm that connected equipment gracefully shuts down according to configured policies. Schedule periodic self-tests and battery health checks to maintain readiness.
