Eaton Tripp Lite Series 1.9kW Single-Phase Switched Automatic Transfer Switch PDU, 2 120V L5-20P / 5-20P Inputs, 16 5-15/20R Outputs, 1U, TAA

The Eaton Tripp Lite Series 1.9kW Single-Phase Switched Automatic Transfer Switch PDU is a mission-critical power distribution unit designed to protect sensitive equipment from interruptions and brownouts. Built for reliability in network closets, data centers, and telecom environments, this 1U PDU combines dual-input redundancy with precise load distribution to keep vital devices online when primary feeds falter. With its robust construction, smart power management capabilities, and flexible outlet configurations, this PDU is engineered to deliver uninterrupted performance for servers, switches, storage devices, and other critical infrastructure.

• Dual-input redundancy with automatic transfer switch (ATS): The PDU features two separate 120V input sources and an integrated automatic transfer switch that instantly routes power from the active feed to the devices on the panel if the primary source becomes unstable or fails. This seamless transfer minimizes downtime and protects against power loss during outages, sags, or noise on one circuit.
• Compact 1U, 19-inch rack-mount form factor: Designed to fit neatly into standard server racks, this PDU optimizes data center real estate while providing robust power distribution for multiple devices. The slim profile helps maintain airflow and cable management efficiency in dense rack environments.
• 16 mixed outlets for versatile device connections: The PDU offers 16 outlets labeled as 5-15/20R, allowing a blend of standard 5-15 and 5-20 receptacles. This flexible outlet arrangement is ideal for housing a range of equipment, from servers and switches to storage controllers and network appliances, all powered from a single, centralized unit.
• High-efficiency power delivery at 120V: With a total power rating of 1.9 kW (approximately 15.8 A at 120V), this PDU provides ample headroom for typical IT racks while maintaining energy efficiency and reducing heat load in the cabinet. The dual-input design enables load-sharing between feeds to optimize performance and reliability.
• TA A-compliant construction and durable build: This unit is designed to meet government procurement requirements with TAA compliance, ensuring suitability for federal or state projects. Its rugged metal chassis and secure mounting hardware deliver long-term durability in demanding environments.

How to Install Eaton Tripp Lite Series 1.9kW PDU

Installations should follow standard data-center practices to maximize uptime and ensure safe operation. Begin by locating a suitable rack with adequate clearance and ventilation. Mount the PDU securely in the rack using the included mounting hardware, aligning it with your other equipment for clean cable management and efficient airflow. Once installed, perform the following steps:

• Connect the first input cord (L5-20P) to the primary power source/feed in your data center cabinet or power distribution system. Ensure the circuit is rated for 20A at 120V and that the breaker is in good operating condition.
• Connect the second input cord to the auxiliary (backup) power source. This dual-feed configuration provides redundancy and supports the PDU’s automatic transfer switch functionality.
• Distribute devices to the 16 receptacles (5-15/20R) in a manner that balances load across outlets and minimizes heat concentration. Group critical devices on separate outlets if possible to further isolate potential failures.
• Power on the system and verify that the PDU recognizes both input sources. Test the automatic transfer switch by simulating a loss on the primary feed and confirming that power continues to reach connected devices via the alternate input.
• Label circuits and document the configuration in your preventive maintenance records. If your facility uses remote monitoring, configure any compatible management interfaces to track input voltage, current draw, and outlet status for proactive performance management.

For best results, integrate this PDU into a broader power monitoring and management strategy. The dual-input, switched design pairs well with redundant power feeds, uninterruptible power supplies (UPS), and network-level monitoring to deliver end-to-end resilience. Regular inspections of power cords, outlets, and rack airflow will help maintain efficiency and minimize the risk of overheating in dense deployments.

Frequently asked questions

• Q: What is the purpose of the dual input cords?
  A: The dual input cords provide redundancy by allowing the PDU to receive power from two independent sources. The automatic transfer switch (ATS) ensures continuous operation by switching to the healthy source when the primary feed experiences a fault or interruption.
• Q: How many outlets does the PDU have and what receptacle types are they?
  A: The unit includes 16 outlets, all of which are mixed 5-15/20R receptacles. This accommodates a wide range of IT equipment with commonly used plug configurations.
• Q: What is the total power capacity?
  A: The PDU is rated at 1.9 kW, providing up to roughly 15.8 A at 120V. This level of capacity is suitable for a typical rack containing switches, servers, and storage devices.
• Q: Is the PDU rack-mountable?
  A: Yes. It is designed as a 1U, 19-inch rack-mountable unit, making it a compact and space-efficient solution for standard IT racks.
• Q: Is this PDU suitable for government procurement?
  A: Yes. The unit is TAA-compliant, meeting procurement requirements for government and related programs, in addition to general RoHS-aligned manufacturing practices.
