CT6872 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 CT6872 has a frequency bandwidth of DC to 10 MHz and a rated current of 50 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.
