ATH1ph single phase | ATH3ph Three Phase Current Transducer for ac or dc Current Sensing

Safety and good working practice when using the ATH current transducer

1. Ensure that all personnel connecting and configuring the ATH are fully trained and conversant with electric shock and fire hazards associated with electricity supplies
2. Ensure the circuit under test is switched off and isolated before connection
3. Only use safety type cables for connections to the ATH probe.  These cables are typically fitted with a 4mm safety type banana connector on either end.  All connections should be insulated to prevent human contact
4. Ensure that the ATH output (lo terminal) is connected to a grounded point on the scope/data logger/measurement system.  Ensure it is a true ground and not just signal low
5. Ensure that the maximum input to output isolation is not exceeded
6. Users should always work in pairs, both parties should be trained and familiar with medical procedures in the event of electric shock
7. Ensure the circuit test is protected with over current protection
8. During installation, avoid all mechanical stress to the ATH probe terminals
9. Do not use the ATH current sensor with the case open
10. Ensure that the storage and operating conditions are clean and dry, do not use where there is risk of explosion

Description

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.
