Description
Hioki's pass-through type AC/DC current sensors can be connected directly to Hioki Power Analyzers and Memory HiCorders. Also, it can be connected to Power Meters, Oscilloscopes, DMMs, etc. by using an optional sensor unit.
The Hioki CT6904A has a frequency bandwidth of DC to 4 MHz (Model CT6904A-1 is DC to 2 MHz) and a rated current of 500 A. It is used in research and development fields such as loss measurement of high-frequency reactors, wireless charging systems, and EV inverter motors.
Use with an instrument with a high input impedance of 1 MΩ or higher.
Key Features
- Combined accuracy with HIOKI power analyzer PW8001 and PW6001 is specified. For details of combined accuracy, refer to the instruction manual.
- 500 A (rms) rated for measurement of large currents
- CT6904A: DC to 4 MHz (±3 dB), CT6904A-1: DC to 2 MHz (±3 dB) wide measurement frequency range
- ±5 ppm excellent linearity
- 120 dB (100 kHz) high Common-Mode Rejection Ratio (CMRR)
