Tripp Lite Metered PDU with ATS (15A, 120V, 8 Outlets)
The PDUMH15ATS is a single-phase ATS PDU that distributes and monitors power across sixteen 120V outlets. It provides real-time local current metering to prevent overloads and enables redundant power for non-redundant network devices. Transfer from primary to secondary power occurs within milliseconds, and a digital load meter reports total load to keep systems within safe capacity. Ideal for rack applications and IT deployments requiring quick, reliable power switching.
Tripp Lite 20A ATS PDU, 200-240V (8 C13/C19 Outlets)
Designed for 200–240V environments, this single-phase ATS PDU supplies eight C13 and two C19 outlets. It enables real-time current monitoring to prevent overloads and supports rapid switching to a secondary power source in the event of primary instability. The digital load meter helps operators maintain safe load levels, ensuring uptime for critical devices in mixed-voltage racks.
Tripp Lite Monitored ATS PDU with 16 Outlets (120V, 20A)
This monitored PDU provides eight outlets on 120V with a built-in management interface for remote status monitoring. The WEBCARDLX-enabled PDU allows full remote access, email notifications, and compatibility with PADM20 for enhanced remote management. Automatic transfer switching ensures seamless handoff to the secondary source within a few milliseconds when primary power becomes unstable.
Tripp Lite Monitored PDU with WEBCARDLX, 16 Outlets (120V, 20A)
Featuring a built-in LX management card, this 16-outlet monitored PDU offers remote management via WEBCARDLX. It supports real-time current metering and load balancing while switching between primary and secondary power sources within milliseconds. The device integrates with secure web browsers and supports SNMP, Telnet, or SSH for comprehensive rack-level monitoring and control.
Tripp Lite 2.9kW PDU with ATS and Remote Management
This 2U rack-mounted, 2.9kW PDU meets high-capacity needs with 24 NEMA 5-15/20 outlets and a NEMA L5-30R. The ATS automatically transfers to the secondary source within 1–5 milliseconds, minimizing disruption. It includes a built-in WEBCARDLX management card for HTML5 remote access, SNMP, and secure communications, making it suitable for larger deployments requiring robust remote monitoring.
Tripp Lite Metered ATS PDU, 200-240V, 8 C13 + 2 C19
Monitored with a built-in LX platform, this 200–240V ATS PDU provides remote monitoring of current and load, ensuring balance across connected devices. The WEBCARDLX interface enables remote status checks, with email alerts and secure access via SNMP, Telnet, or SSH. The ATS switches to the secondary source in 2–7 milliseconds to maintain uninterrupted operations.
Buying Guide: Key Considerations for Auto-Transfer Switch PDUs
When selecting an ATS PDU, consider these factors to align with your environment and reliability goals:
- Voltage and current ratings: Ensure compatibility with your equipment’s voltage (120V vs. 200–240V) and current (15A, 20A, or higher) requirements.
- Outlet configuration: Choose the number and types of outlets (C13, C19, NEMA variants) to match your devices and cable management needs.
- ATS transfer time: Look for milliseconds-level transfer to minimize downtime during source changes; faster is generally better for mission-critical gear.
- Monitoring and metering: Real-time load meters and current monitoring help prevent overloads and optimize power distribution.
- Remote management: WEBCARDLX or similar network interfaces enable secure remote monitoring, alerts, and configuration; consider compatibility with your existing management tools (SNMP, SSH, etc.).
- Rack compatibility and form factor: Ensure the unit fits your rack space (1U, 2U, etc.) and supports your mounting needs.
- Power sources: Evaluate whether you need dual input cords or dual power sources (primary/secondary) for redundancy.
- Warranty and compliance: Look for manufacturer warranties and compliance with standards (e.g., TAA for certain environments).
For deployments requiring centralized power management, ATS PDUs provide fast switching, comprehensive monitoring, and remote control to support uptime, load balancing, and proactive maintenance across data centers and IT closets.
