Three phase power transducer


  • ​ENTRIES:Part Number GuideData SheetFAQ
  • This device is an electrical isolation transducer of 3-phase active, reactive power, power factor, and true RMS measurement. Its input is isolated from output signal, and output linear standard analog signal. Through the internal switch, can switch to active, reactive power and power factor measurement of 3-phase 3-wire and 3-phase 4-wire. The product can be widely used in electric power, communications, railway, industrial control and other fields.
