WM30 Smart Modular 3-Phase Power Analyser
Three-phase smart power analyser with built-in advanced configuration system and LCD data displaying. Particularly recommended for the measurement of the main electrical variables. WM30 is based on a modular housing for panel mounting with IP65 (front) protection degree.
Moreover, the analyzer can be provided with digital outputs that can be either for pulse proportional to the active and reactive energy being measured or/and for alarm outputs.
The instrument can be equipped with the following modules: RS485/ RS232, Ethernet, BACnet-IP, BACnet MS/TP or Profibus DP V0 communication ports, pulse and alarm outputs. Parameters programming and data reading can be easily performed by means of UCS (Universal Configuration Software).
