PMU
Power Meter Unit
Device Description
Inavitas PMU (Power Meter Unit) is a new generation network analyzer that measures and enables real time monitoring of energy parameters. Inavitas PMU (Power Meter Unit) monitors up to 5 channel three phase circuits or 15 channel single phase circuits or any combination of single or three phase circuits.
This flexibility makes Inavitas PMU perfect for multi-tenant facilities such as distribution substations, office buildings, data centers and shopping malls. The user can monitor all energy parameters in real time and configure current and voltage polarities, transformer ratios and serial communication settings easily via Inavitas PMU user interface software.
