Description
HC power voltage transducers are with reading base accuracy conversion ideally applied for an accuracte
measurement of AC voltage input, with self power mode of non external power design to simpliz wire
connection particularly useful for user in field application.
Models are available for one voltage & three voltage units with average responding scaled to RMS output.
