The TASC Systems 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. The output that is directly proportional to the input signal. The sensors are self-powered (i.e. no auxiliary required) average sensing RMS calibrated current transducers, mA and voltage outputs are available. The sensors are average sensing RMS calibrated, live zero current transducers. The sensor is true RMS sensing RMS calibrated allowing measurement of distorted waveforms of up to 9th harmonic with a crest factor of 5. The sensor is typically used in current measurement where the distorted waveform is common, such as thyristor drives The above units are used to measure current in energy management systems, switchboards, generator and telemetry controls. Isolation of 4kV is provided between the input and output signal, allowing the output to be fed to conventional analog meters, digital meters, PLC, and computer systems.
