Delivering Wide-Operating Temperature Range and High-precision Current Measurement

Hioki pass-through AC/DC current sensors are best-in-class devices for use with power meters, Memory HiCorders and high performance oscilloscopes. The CT6862 is a DC to 1 MHz/50 A sensor, and this is ideal for capturing current signals from switching power supplies, inverters, power conditioners, etc.

CAT III 1000 V

Use with an instrument with a high input impedance of 1 MΩ or higher.

Key Features

  • Combined accuracy with HIOKI power analyzer PW8001, PW6001 and PW3390 is specified. For details of combined accuracy, refer to the instruction manual.
  • Wide-bandwidth DC to 10 MHz excellent frequency characteristics
  • Applications in the fields of electric and hybrid electric vehicles
  • Wide operating temperature range(-40°C to 85°C) fit for automobile applications
  • Ideal for evaluation of solar power generation and fuel cells to measure battery charge and discharge and the secondary side of inverters
  • For observing waveforms to be used with the oscilloscopes or Memory HiCorders (use with Sensor Unit)
