AC/DC CURRENT SENSOR CT6862-05

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)

Ideal for comprehensive evaluation of wide-bandwidth and high-precision inverter motors

The CT6862 series are wide-bandwidth and high-precision AC/DC current sensors that achieve high accuracy measurement of both small- and large-current signals. They can be used for a wide variety of applications in the fields of electric and hybrid electric vehicles, inverters and other devices, alternative energy sources such as solar power and fuel cells, as well as home electronic appliances and system equipment.
