CVM-144
POWER ANALYZER
A complete analysis permits the user an on-site display of the measured parameters, as well as a further detailed management of logged data by means of the appropriate software.
To satisfy our customers’ needs, NMI offers the CVM 144 power meter, which measures, calculates, and displays main electrical parameters (37 discrete variables) from any industrial three-phase power system, either 3 or 4 wire configurations.
