Power (Watts & Vars) Transducers

Power transducers measure AC power (active, reactive or both) either directly or through voltage and/or current transformers. The transducer converts the AC power signal to either a DC mA or DC voltage output which is directly proportional to the input signal value. Models are available for single phase and three phase, balanced and unbalanced loads and are available with a zero based or live zero output. Combined Watt & Var transducers are also available with two galvanically isolated outputs, one proportional to active power (Watts) and the other proportional to reactive power (Vars). All power transducers are available self powered or powered from a large choice of AC or DC auxiliary power options. The 4kV isolated output signals can then be fed to analogue meters, digital meters, PLC's or building management systems.
