ISKRA MC 744 Multifunction Meter
Meters from MC7x4 series are designed for environments where beside measurement of three-phase electrical power network additional analogue or digital measurements/controls must be made without additional hardware (PLC, OPLC, ...). Meters are housed in enclosure 144mm x 144mm.
