- A valid alternative to the individual traditional panel instruments, in order to save mounting time and space with a better actual reading of measures. - More than 40 possible parameters readable in their 4 LED displays. - Their low cost and the possibility of displaying two different parameters simultaneously, due to their fourth display (i.e. the phase to phase Voltage and the three currents) make them advisable as a replacement of singular Ammeter or Voltmeter. - True rms measures with memory of maximum values. - For single phase and three phase applications (even unbalanced) of 3 or 4 wires, for - Low and Medium Voltage connections. - They are fitted with an ample selection of a transformation relation ratio for the external CT's and VT's, so as with a multi-voltage power supply. - Panel and DIN rail mounting versions. - Pulse and/or serial communication by RS485 with Modbus protocol.
