Description

Function :

Power Transducers are designed for the purpose of monitoring the Active or Reactive or Apparent power drawn by Single Phase or Three Phase AC electrical loads. The power is electronically computed from the input signals from C.T. & P.T. in the electrical circuit and 4-20 mA or Vdc output (proportional to power drawn by the load) is provided.


  Solid state design using time division multiplexing technology.
  Individual models are available which measure Active or Reactive or Apparent Power.
  C.T. & P.T. based design permits use in L.T. as well as H.T. Circuits.
  mA /Vdc output signals give compatibility with DCS/PLC/SCADA systems.
  Output is galvanically isolated from input, supply & enclosure.
  Separate models for Single Phase & Three Phase (Three Phase – 3 wire / 3 Phase-4 wire circuits).
  Models with dual channel outputs are available optionally.
  Unit with built in digital display for kW is available optionally.
  DIN rail mounting enclosure for non indicative type & Panel door mounting for unit with Digital Display.
  Models suitable for import/ export of power.
