Typical Applications |
| The M100 series voltage transducers are designed to measure AC voltage in single and 3 phase systems. They convert the A.C. signal to a D.C. output that is directly proportional to the input signal. The M100-VA1, VA3 are self powered (ie no auxiliary required) average sensing RMS calibrated voltage transducers, mA and voltage outputs are available. The M100-VR1 is true RMS sensing RMS calibrated allowing measurement of distorted waveforms of up to 9th harmonic with a crest factor of 5. The VR1 is typically used in voltage measurements where distorted waveforms are common such as in thyristor drives. The above units are used to measure voltage in energy management systems, switchboards, generator and telemetary controls. Isolation of 4kV is provided between the input and output signal, allowing the output to be fed to conventional analogue meters, digital meters, PLC, and computer systems. |
