DC Current Sensors for Industrial, Automation, Welders, DCS and Electric Vehicle Test

The CTH current sensors convert dc current to an isolated voltage or mA output with instantaneous precision. The CTH output is a faithful reproduction of the measured current, whether ac or dc. All popular EV types, process control voltage and current loop outputs are available. Through hole or split core options mean that connection is non-intrusive and straightforward. The available input range of the CTH sensors is any value from 1A to 40000Adc. Optional dc offset control allows nulling of residual dc current to ensure best use of the output span. The sensor power input is designed to operate over a wide voltage range associated with process control and sub-station auxiliary dc supply systems. Active Hall Effect sensor technology allows measurement from DC-150kHz (depending on the sensor type) along with fast step response. The CTH can be used to provide an instantaneous output for ac currents. Typical applications are found in process control systems like PLC or SCADA, transportation, telecommunications, dc drives, welding and circuit breaker trip coils. For all CTH models, a NIST/NPL (UKAS) traceable calibration certificate and certificate of conformance is supplied.
