AC Current Transducers


AC Current transducers from Ohio Semitronics, Inc. are available to measure absolute average or true RMS AC currents in ranges from 5mA through 300,000A. Transducers are available as single or three-phase with wired inputs for external current transformers or may incorporate the CT’s into the same package, in either solid core, split core (clamp-on), or DIN-Rail packaging.


Available outputs include 0-1mA, 4-20mA, 0-10Vdc, and 0-5Vdc with customized input ranges and output formats available on request. OSI achieves product success by using a variety of measurement technologies, including Hall Effect, open and closed loop circuits, as well as flux gate, and Rogowski techniques.
