Hioki AC/DC clamp sensors are best-in-class current sensors for use with power meters, Memory HiCorders and high performance oscilloscopes. The CT6841 is DC to 1 MHz/20 A sensors, ideal for capturing signals during the efficiency testing of batteries, inverters and power conditioners.

Key Specifications:

  • Rated current: 20 A AC/DC
  • Max. allowable input: 40 A rms (requires derating)
  • Frequency characteristics: Amplitude: DC to 1 MHz
  • Phase: DC to 300 kHz
  • Amplitude and Phase accuracy:
    • DC ±0.3 % rdg. ±0.05 % f.s. (Phase: Not defined)
    • DC < f ≤ 100 Hz ±0.3 % rdg. ±0.01 % f.s. (Phase: ±0.1°) Defined to 1 MHz
  • Power consumption: 5 VA max. (at 20 A/55 Hz, ±12 V power requirement)
  • Output voltage:
    • 0.1 V/A (CT6841), 0.01 V/A (CT6843)
      (voltage output with the Sensor Unit, use with a device having a 1 MΩ input resistance or higher)
  • Core diameter: φ 20 mm (0.79 in)
