The VTH3ph and VTHR3ph voltage transducers convert dc or ac voltage to an isolated voltage or current loop output.
The VTH3ph and VTHR3ph voltage transducers convert dc or ac voltage to an isolated voltage or current loop output. The Available VTH3ph models cover the range from 0.333V to 600Vrms, with fast response capability, the Model VTHR3ph offers true rms conversion DC-50kHz along with Voltage Analysis. VTH3ph sensors are available in ac only or dc+ac configurations.
The instrument power input is designed to operate over a wide voltage range associated with process control and sub-station auxiliary dc supply systems. Some typical applications are voltage monitoring in PV photo-voltaic, wind turbines, ac and dc drives, process control, rail transportation. For all products, a NIST/NPL/UKAS traceable calibration certificate of conformance is available.
