HIOKI CT6847 AC/DC Current Clamp/Current Sensor
The HIOKI CT6847 is a precision AC/DC current clamp featuring fluxgate technology. It has a rated current of 2000 A and a basic accuracy of ±0.15% of the measured value. The clamp operates over a wide temperature range of -40... +85°C and covers a bandwidth from DC to 70 kHz. The maximum measurable conductor diameter is 50 mm, and the clamp’s cable length is 3 m.
- Current clamp/current sensor for DC currents up to 2000 A, AC currents up to 1400 ARMS.
- Frequency bandwidth DC to 70 kHz.
- Basic accuracy ±0.15% of the measured value.
- Temperature range -40...+85°C.
- Output signal 1 mV/A.
- Applications:
WLTP (Worldwide Harmonized Light Vehicles Test Procedure) testing on electric vehicles such as high-performance EVs, electric trucks, and other electrified vehicles.
Design validation of high-performance electric drives, including electric construction machinery and electric aircraft.
Current measurements for high-performance UPS systems and power conditioners.
