Basic rack PDUs are little more than outlet strips. They deliver electrical power to IT devices and that is about all they do.
In addition to delivering electrical power, metered rack PDUs provide information about the power that is being consumed. It may be as simple as the voltage and the power being consumed by the PDU in total or it may provide much more power information and breakdown that information by each individual outlet. There is a wide range of PDUs that could fall under the description of a metered PDU.
