MPxWx & MPxRx - POWER MEASURING TRANSDUCER - WATT CLASS 0,5 & VAr CLASS 1
- Active Power (Watt) or Reactive Power (kVAr) Transducer for balanced or unbalanced load
- Precision true RMS class 0,5 (kW) and class 1 (kVAr) measurement, not affected by any waveform distortion
- For use with 1A or 5A current transformers
- Very fast analogue output response time (<50mS)
- 1500V Galvanic isolation
The digital controlled MPxWxE or MPxRxE is a precision power transducer for balanced or unbalanced load system active (W) or reactive (Var). To be used in applications that require a very fast response, precision monitoring of active/reactive power. Ideal for systems for regulation and control of the load on generators, motors and inverters.
The unit measures the voltage and current true r.m.s. value, and accuracy is independent of any wave form distortion.
The unit has ONE very fast response analogue output signal, with amplitude proportional to the measured active power (W) or reactive power (VAr) level. Note that the instrument needle is a class 1,5 moving coil.
The standard version takes the auxiliary voltage from the monitored voltage on terminal 1 & 2. It can be delivered with separate AC (term. 26 & 27) or DC (term. 31 & 32) auxiliary voltage but that must be specified when ordering.
The noise-immune mA output is isolated from both the C.T. and voltage inputs and auxiliary power.
A green "Supply On" LED indicates the auxiliary supply presence.
If output is used for remote meter reading, we recommend 0-1mA for the slave indicator.
