The VTH and VTHR voltage transducers convert dc or ac voltage to an isolated voltage or current loop output. The Available VTH models cover the range from 50mV to 500Vrms, operation with a fast response capability, the Model VTHR offers true rms conversion DC-10kHz. VTH sensors are available in ac only or dc + ac configurations.
The sensor power input is designed to operate over a wide range associated with process control and sun-station auxiliary dc supply systems. Some typical applications are voltage monitoring in dc drives, process control, rail transpiration and circuit breaker trip coils. For all products, a NIST/NPL/UKAS traceable calibration certificate of conformance are available.
