LEM USA (Milwaukee, WI) introduced its new AK, AKR and DK Series of ac/dc current transducers, which reduce installation time 50 percent by combining a current sensor and a transducer suitable for direct PLC interface in a single package. The new transducers are well adapted for retrofit in existing installations.
The transducer’s clamp-on function allows mounting on-site without disconnecting cables or disassembling bus bars. The transducers are available for ac current (AK and AKR Series) and dc current (DK Series) from 2A to 500A. The transducer can be self-powered with a 0V to 5V or 0V to 10V output, loop-powered with a 4mA to 20mA output, or powered from a +24Vdc power supply for the dc current version. The averaging technique used by the AK family is suitable for strictly linear loads.
