HIGH AC CURRENT TRANSMITTER

(wide bandwidth)
Functions & Features
• Detecting high current at the flexible current probe and providing a porportional low-ripple standard signal appropriate for computer use
• Wide frequency band can be accepted
• Clipped around a conductor without disconnecting the conductor
• Rogowski coil type
• Isolation up to 2000 V AC
• High-density mounting
Typical Applications
• Measurement in tight places as never before possible
• Monitoring load current of motors employing inverters
• Detecting failures of a pump or other device by monitoring abnormal load current of motors
• Monitoring current of electric welding machine
