Power Transducer Series LT-UNIT

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

• Over-voltage clamp element for safety in open

circuit

• High-density mounting

Typical Applications

• Centralized monitoring and control of motors at

a supervisory panel

• Monitoring abnormal load current at motors to

detect pump malfunctions
