Description
HC power current transducers are with design of reading base accuracy & non zero adjustment required
very ideally applied for an accuracte measurement of AC current input.
Self power mode design is to simplize wire connection without external power particularly useful for user in
field application.
Models are available for one voltage & three voltage units with average responding scaled to RMS output.
