Field Voltage Transducers

Transducers designed for the measurement of generator field voltages. The input is rated for 2000 VDC with isolation of 3500 VDC. Standard output is either ±10 VDC (model FVT-01-10V) or 4-­20 mA (model FVT-01-420m). Housed in a fiberglass box with watertight fittings for cable entry and exit.
