Incoming Energy Monitoring This functionality enables the PDU to measure the total incoming energy consumption. The unit monitors the complete flow of current, voltage, power, and energy (kWh) from the power source into the PDU.

This data provides valuable insights for analysing and optimising energy usage within the data centre or server room – supporting cost control, capacity planning, and the identification of inefficiencies.

If the PDU is configured with multiple phases, energy consumption is measured per phase. If divided into multiple protected groups, consumption is monitored individually per group.

Measured parameters include: Voltage (V), Voltage dips/spikes (V), Current (A), Peak current (A), Active power (W), Apparent power (VA), Reactive power (VAR), Energy (Wh), Apparent energy (VAh), Total harmonic distortion (%), Crest factor, Frequency (Hz), Power factor.

Monitoring energy consumption also helps improve Power Usage Effectiveness (PUE) – a key metric for energy efficiency in data centres – and supports compliance with the EU Energy Efficiency Directive (EED).

Individually Monitored Outlets This functionality provides real-time insight into the energy consumption of each connected IT device through individually monitored outlets. It enables precise measurement of voltage, current, power and energy (kWh) per outlet, allowing organisations to optimise energy management and cost allocation.

Ideal for capacity planning, predictive maintenance, and cost distribution in environments such as colocation facilities, it also enables detailed energy analysis, real-time monitoring and reporting, and seamless integration with DCIM tools.

This functionality supports sustainability goals by improving energy efficiency – for example, by identifying so-called “zombie servers” that consume power but contribute no real workload. Eliminating such unused resources leads to significant cost savings and improved operational efficiency.
