Electrical Digital Transducers
HC Transducers are precision instruments with high accuracy designed for process, industrial or utlity applications. They are available in DIN-Rail enclosures for easy installation on DIN-Rails or on flat surfaces, incorporate Hall-Effect current sensors and can be used with external current and potential transformers. They provide a high voltage isolation between input and output. Models are available for measuring Watts, Watt-Hours, True RMS or Mean Voltage / Current, KVA and KVAR. Single-Channel and Three-Channel models are included.
