CT6873 AC/DC Current Sensor

CT6873 AC/DC Current Sensor

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 CT6873 has a frequency bandwidth of DC to 10 MHz and a rated current of 200 A. It is used for R&D, quality evaluation, manufacturing, and maintenance in markets such as wireless charging systems, inverter motors for industrial equipment, power conditioners for PV, and quick charging facilities for EVs.

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