MODEL: CTS2 CTS2 SPECIFICATIONS ES-1902 Rev.2 Page 1/4 http://www.m-system.co.jp/ Plug-in Signal Conditioners M-UNIT 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 (1.97) 123 (4.84) (3.15) mm (inch) MODEL: CTS2–[1][2]–[3][4]
