Преобразователь измерительный ПР-01-ТК
  • Continuous measurement three-phase network without neutral parameters: currents and voltages on two phases, active, reactive, and total power, power factor.
  • Programmatically setting up nominal current on measuring inputs.
  • Active, reactive, total power and power factor calculation by two wattmeters method.
  • Two galvanic isolated unified current outputs.
  • Nominal current value programmatically setting up for each current output.
  • RS-485 interface, Modbus RTU protocol.
  • Setting up via control unit PN-01-TK or special software via RS-485 interface.
