PMU
Power Meter Unit
Device Description
Endoks PMU (Power Meter Unit) is a new generation network analyzer that measures and enables real time monitoring of energy parameters. Endoks 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 Endoks 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 Endoks PMU user interface software.
