A Metered PDU is a power distribution unit equipped with sensors that continuously measure and report key electrical parameters such as voltage, current, power, and energy consumption. Unlike basic PDUs that only distribute power, metered models provide real-time and historical visibility into how much electricity is being used at the inlet, circuit, or individual outlet level.
Key capabilities of Metered PDUs
- Inlet metering: Measures total power drawn by the entire PDU, giving a clear view of rack-level consumption.
- Circuit or branch metering: Tracks power on individual circuits for better load balancing and overload prevention.
- Outlet-level metering (on advanced models): Provides granular data for each device, supporting precise capacity planning and chargeback models.
- Local and remote display: Shows live readings on the unit itself and often transmits data via network protocols for centralized monitoring.
Metered PDUs are widely used as the practical entry point into intelligent power management. They help operators avoid stranded capacity, identify underutilized or overloaded circuits, and build accurate energy-consumption baselines—especially valuable in environments with fluctuating loads from GPU Servers and AI Accelerators.
Metered PDU and ATTOM
In Attom Technology’s modular deployments, Metered PDUs deliver the foundational power visibility required for safe and efficient operation of dense racks. By feeding accurate consumption data into monitoring systems, they support precise capacity planning and energy accountability across AgileCore and other high-density platforms, without requiring the full switching functionality of more advanced intelligent units.
