2- Eltime
Power (Watts & Vars)
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).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.
