Toroidal, Solid-core Voltage/ Current Transformer - AC Voltage Measurement - Intelligent Devices

TV31 Series Current Style, PCB Mounted Voltage Transformers

The Current-style AC Voltage Transformers are essentially a 1:1 primary to secondary ratio AC current transformer used to measure an AC primary voltage. The basic application design uses a current limiting resistor in series with the current transformer primary input. An I/V (current/ voltage) switching circuit is used to transform the current transformer secondary output to a signal proportional to the AC primary voltage that is at a level suitable for micro-processor-based applications. The small physical dimensions are designed specifically for integration into products which require exceptional accurate signal transformation with low phase shift while exposed to harsh environmental operating conditions.
