The “Multi-E4-MU” is used for the simultaneous conversion and separation of all energy-technical variables for sinusoidal alternating variables into 4 impressed direct current and direct voltage signals. The measurement is possible in alternating current networks and three- or four-wire three-phase systems with the same or unequal load. The 29 measured values can be further processed via an Ethernet LAN interface. Up to 13,000 readings can be stored in the internal memory. You can also display the measurement results via a web browser or read and process them via the http, TCP / IP or Modbus TCP protocol. Two additional outputs are available as limit or pulse outputs.
