Best for: Use cases needing straightforward metered power without additional smart features, ideal for established data centers or office server rooms.

Caution: Fewer advanced features than ATS models; plan for potential redundancy separately if required.

Tripp Lite Metered PDU PDUMH20

Check Price on Amazon

Reference features: 20A single-phase, 12 outlets (NEMA 5-15/20R), 15 ft cord, 1U rack-mount. Metered PDU with built-in two-digit load meter displaying current in amps. Best for higher current, compact 1U deployments with clear load visibility.

Best for: Smaller racks needing higher current per circuit and easy load monitoring, suitable for varied IT gear within a single rack line.

Caution: Agency de-rating to 16A may apply in continuous operation; verify real-world load against rating.

Buying Guide

What is a metered PDU and why choose one?

A metered PDU provides real-time load information for connected devices. This helps prevent overloads, plan capacity, and optimize cooling and power distribution in racks.

Key considerations for selecting a metered PDU

• Input voltage and phase: Ensure compatibility with your power supply (120V vs. 208–240V; single-phase vs. multi-phase).
• Current rating: Match the PDU current rating to your equipment’s power needs; consider potential derating in continuous operation.
• Outlet count and type: Count how many devices you need to power and ensure outlets (C13, C19, NEMA types) fit your equipment cables.
• Redundancy and ATS: If uptime matters, look for automatic transfer switches or dual-input designs for power source redun­dancy.
• Form factor: 1U vs. 2U, horizontal vs. vertical mounting affects space and cable management.
• Monitoring features: Digital meters, LCD displays, and remote monitoring capabilities improve visibility and management.
• Warranty and support: Consider the vendor’s warranty length and service options in your procurement plan.

Which features matter most by use case?

• High-density storage or compute racks: Higher outlet counts (C13/C19) and 200–240V input help consolidate power in a single PDU.
• Redundant networks or mission-critical gear: ATS PDUs minimize downtime by switching sources quickly.
• Small racks or quiet environments: Compact, 1U units with straightforward meters fit easily while providing essential visibility.

Common limitations to watch for

• Derated current: Some PDUs are de-rated for continuous operation; verify continuous current limits and runtime expectations.
• Compatibility: Not all PDUs work with every power source type; confirm input/output configurations align with your rack.
• Outlets vs. devices: A large number of outlets can complicate cable management if devices are densely packed.

Installation and maintenance tips

• Label outlets and cords clearly to simplify future upgrades or maintenance.
• Plan cabling paths to avoid obstruction of airflow and prevent accidental disconnections.
• Use the LCD or remote monitoring data to track load trends and plan for capacity expansion.

Frequently Asked Questions

• What is the difference between metered and intelligent PDUs? Metred PDUs show current load; intelligent PDUs offer remote monitoring, alerts, and control.
• Do I need a dual-input ATS PDU for a single-critical device? Not always, but it helps if uninterrupted power is essential and you can source a second power line.
• Can a metered PDU support high-wattage servers? Yes, if the input and outlet types match, and the current rating supports the load.
• Is a 1U PDU suitable for dense equipment? For compact spaces, yes, but ensure outlet and load requirements fit within 1U constraints.
• How do I know which outlets I need? Map each device’s power plug type to ensure compatibility (C13, C19, or NEMA variants).
• Should I choose a PDU with a digital load meter? A digital meter simplifies load monitoring and helps prevent overloading.
