AC CURRENT TRANSDUCER
(clamp-on current sensor; RMS sensing)
Functions & Features
• Converts an alternating current into a standard
process signal
• Easy-to-install clamp-on type current sensor
without needing a current transformer
• Clamp-on current sensor included
• Wide input range from 10 A up to 600 A
• Input frequency 50 / 60 / 400 Hz
