M100-AA3 3 ph. self powered ave. sensing RMS calibrated M100-AL3 3 ph. aux powered ave. sensing RMS calibrated TYPICAL APPLICATIONS The M100 series current transducers are designed to measure A.C. Current 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-AA1 AA3 are self powered (i.e. no auxiliary required) average sensing RMS calibrated current transducers, mA and voltage outputs are available. The M100-AL1 AL3 are average sensing RMS calibrated, live zero current transducers. Auxiliary is required to provide power, so that 4mA output signal is present, when the input is zero. The M100-AR1 is true RMS sensing RMS calibrated allowing measurement of distorted waveforms of up to 9th harmonic with a crest factor of 5. The AR1 is typically used in current measurement where distorted waveform is common, such as thyristor drives. The above units are used to measure current in energy management systems, switchboards, generator and telemetery 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. OPTIONS 1. Non standard inputs / outputs only as far as technically acceptable. 2. A.C. Auxiliary in range 57.7 to 450 volts 3. Calibration at nominal Hz 35.....450Hz 4. Calibration at temperature other than 23° |
