Current Transducers

Ohio Semitronics manufactures DC current transducers, as well as both absolute average and true RMS measuring AC Current transducers in ranges from 5 milliamps through 300,000 amps. All are available in a variety of form factors. Standard outputs include: 0-1 mA, 4-20mA, 0-10Vdc and 0-5Vdc. Customized input ranges and output formats are available on request.



AC Current Transducers


AC Current transducers are available to measure absolute average or true RMS AC currents in ranges from 5 milliamps through 300,000 amps. 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 or split core (clamp-on) packages. DIN Rail-mounted packaging is also available.


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