S504C-80: Three-phase 3/4 wire 80A energy meter with S504C-80 communication interface

With direct connection up to 80A, S504C-80 is a compact 4 DIN module energy meter (also available MID certified) for energy measurement in industrial and civil environments, with integrated communication (RS485 Modbus, M-Bus or Ethernet). In addition to energy, the meter measures the main electrical parameters and makes them available on the integrated COM port. Totalizers and instantaneous powers are shown on the LCD display. The COM port allows managing the meter connected to a remote station. This data is transmitted via RS485, M-Bus or Ethernet depending on the model.
