The ATH current transducer range converts dc or ac current to an isolated voltage or current loop output. The ATH sensors are direct connecting, meaning they connect in the circuit under test eliminating CT limitations and errors. The available ATH models cover the range from 0-100mA to 0-5Arms, operating with fast response capability. ATH are instantaneous conversion, the ATHR are rms converting where the ATHR device will give true rms conversion even with distorted waveforms, over DC-10kHz range.
The sensor power input is designed to operate over a wide range associated with process control and sub-station auxiliary dc supply systems. Some typical applications are current monitoring in energy metering, industrial control, ac/dc drives, process control, rail transportation and circuit breaker trip coils. For all products, a USA NIST, UK NPL traceable calibration certificate and certificate of conformance are available. ATH and ATHR sensors are available in ac only or dc + ac configurations.
