  • Comply with MID EN50470 Class B

  • Build in Modbus RTU communication

  • Compact size of 54mm width

  • Direct Connection Up to 100A

GEM540 is an advanced digital multi-function power meter and part of the smart Graphene-Meter-Series, which can be connected to loads up to 100A (direct). The device measures all-important system values like active energy, reactive energy, current, voltage, power, power factor, frequency and max demand. 

Bi-Directional measurement makes it an ideal choice for power generation plants like solar/PV fields. Standard industrial interfaces like Modbus RTU ensure a smooth exchange with any other system. The front panel allows the user to check data and set up the meter via easy-to-access buttons. To provide the highest safety and to prevent unwanted changes in the settings, all communication parameters are password protected.
