XTM35SC current / voltage meter

XTM35SC Other unit names:

  • VE EMDIN02


The XTM35SC is an inexpensive current meter that can be purchased (e.g. on Amazon). It measures consumption, voltage and current on one phase. It does not require an external measuring ring. Suitable for home automation and smaller equipment. Of course, it is not MID compliant. The measurement results can also be queried remotely via Modbus RTU communication.

Description:

  • 35 mm standard rail mounting according to the DIN EN50022 standard.
  • Bipolar width (module 17.5mm), conforms to the DIN43880 standard
  • Standard configuration 5 + 1 digit display (9999999.1kWh) LCD. Function can be selected (display voltage current, power, frequency, power factor).
  • Setup measurement single-phase two-wire active energy consumption. It's nothing to do with the direction of load current flow. Compliance with GB / T17245.321-2008 standard.
