5.1.4 Consumption metering - only NETIO PowerPDU 4C and NETIO
4All
All power measurement and metering functions are available on the NETIO PowerPDU 4C and
NETIO 4All models only.
Figure 9. Consumption metering
Power in watts [W] is the product of the immediate current and voltage (P = U * I).
Current in amps [A] shows the immediate current flowing through the given output.
True Power Factor expresses the ratio of active and apparent power, or the ratio of resistance and
impedance. A value less than 1 means that there is a phase difference between the current and the
voltage, i.e. higher energy losses compared to a purely resistive load.
Energy in watt-hours (Wh / kWh) is the cumulative energy consumed over a time interval. The
value is the total consumption at the given input from the selected date to the present.
By default, the cumulative energy consumption is counted from the time the NETIO PowerPDU 4C
or NETIO 4All was first powered on. To reset the counters at all outputs, go to Settings > System
and click Reset Energy Consumption Counters below the line. The energy consumption will be
measured from this moment onwards.
Voltage in volts [V] is the same for all outputs.
Frequency in hertz [Hz] is the same for all outputs.
