For AC applications, most transducers will not accept a direct current input over 20A. For higher amperages, current transformers are utilized. Ohio Semitronics manufactures and supplies many styles of current transformers with various inputs and secondaries. All Ohio Semitronics Transducers, depending upon input, are supplied and calibrated with a CT before shipment.
