CLAMP ON AC/DC SENSOR CT9691

CAT III 600 V

Hioki AC/DC clamp sensors are best-in-class current sensors for use with power meters, Memory HiCorders and high performance oscilloscopes. The CT9691 and CT9691-90 with sensor unit attachment is a DC to 10 kHz/100 A sensor, ideal for capturing current signals from solar power generation systems, UPS and batteries.

Key Features

Ideal for solar power generation systems, UPS and battery testing
Large current measuring applications in the fields of electric and hybrid electric vehicles (CT9693)
Wide-bandwidth DC to 10 kHz (CT9691), 20 kHz (CT9692) excellent frequency characteristics
Applications in solar power generation, battery charge and discharge, and measuring the secondary side of inverters
For observing waveforms in combination with oscilloscopes or Hioki Memory HiCorders (use with the CT6590)

Model No. (Order Code)

CT9691	Discontinued, sensor only, 100 A AC/DC
CT9691-90	Discontinued, Set model with the CT6590, 100 A AC/DC

Note: To use the CT9691/ CT9692/ CT9693 sensor with the Hioki PW3198 Power Quality Analyzer or the Hioki Memory HiCorder series, it must be connected and powered via the Sensor Unit CT6590.
Note: The CT9691/ CT9692/ CT9693 sensor may also be used with the Clamp on AC/DC HiTester 3290/ 3290-10 (without the Sensor Unit CT6590).
