• Converting an alternating current from a current transformer into a standard process signal
• Wide range of frequency can be accepted thanks to the incoporated wide-range CT
• Isolation up to 2000 V AC
• High-density mounting Typical Applications
• 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) 127 (5) (3.15) mm (inch) MODEL: CTH–5[1]-[2][3]
