Eaton 9PX 5kVA 120V Stepdown Transformer - 18 NEMA 5-20R Outlets, 60 Hz, L6-30P Input, 3 ft. Cord, 3U Rack/Tower

The Eaton 9PX 5kVA 120V Stepdown Transformer is engineered to bridge the gap between high-voltage UPS systems and sensitive 120V equipment. With a robust 5 kVA power rating, it converts 208V input into a stable 120V output, delivering clean power distribution across a generous outlet bank. Designed for data centers, labs, and professional workspaces, this unit features 18 NEMA 5-20R outlets organized in two banks, enabling flexible, scalable power distribution from a single, centralized transformer. The rugged 3U rack/tower enclosure makes it easy to integrate into existing rack systems or place on a stable surface, helping you maximize space efficiency while keeping critical devices powered and protected.

• Power quality and isolation: This transformer delivers clean, isolated 120V power from a 208V source, helping to minimize electrical noise, voltage fluctuations, and common-mode glitches that can affect sensitive electronics. By providing a dedicated, conditioned output for connected equipment, it enhances overall system reliability and can help extend the life of UPS systems and connected devices.
• Extensive outlet distribution: With 18 NEMA 5-20R outlets arranged as two banks of nine, there is ample capacity to power servers, switches, storage devices, lab instruments, and office equipment from a single unit. The dual-bank design supports logical grouping of devices by function, making cable management and power planning simpler in busy racks and cabinets.
• Input connection and 60 Hz operation: The unit uses a standard L6-30P input plug and is designed for 60 Hz operation, aligning with most UPS systems and 208V power sources used in data centers and professional environments. The 3 ft input cord offers convenient reach from your power source to the transformer without creating excessive slack or tension on cables.
• Rack/tower mounting versatility: The 3U enclosure is purpose-built for rack-mount deployment or stable tower placement, giving you flexible integration options in constrained spaces. This compact footprint fits within standard 19-inch racks and cabinet layouts, helping you optimize space while maintaining easy access for service and monitoring.
• Reliability and protection for critical loads: Engineered to support demanding workloads, this transformer provides reliable voltage conversion and distribution for essential equipment. It helps shield connected devices from mains irregularities and supports consistent performance in networked environments, laboratories, and enterprise IT spaces while maintaining a durable, professional enclosure suitable for rigorous use.

how to install Eaton 9PX 5kVA 120V Stepdown Transformer

• Choose a stable, well-ventilated location and mount the transformer in a 3U rack or place it securely on a flat surface suitable for equipment in a controlled environment.
• Connect the input plug (L6-30P) to a compatible 208V supply or UPS that is rated for your overall load. Ensure the supply is within the transformer's design specifications and meets local electrical codes.
• Plan load distribution carefully by connecting devices to the two banks of NEMA 5-20R outlets. Distribute high-current devices evenly to minimize heat buildup and voltage drop across outlets.
• Verify grounding and ensure all grounding conductors are properly connected in accordance with applicable electrical codes and the equipment’s grounding requirements. A solid ground is essential for safety and performance.
• Power on the system and validate output with a reliable voltmeter or test equipment to confirm a stable 120V across the outlets before connecting critical devices. Perform a startup sequence with non-essential equipment first to confirm proper operation and protection mechanisms.
