CT6863-05 – AC/DC Current Sensor


Delivering Wide-Operating Temperature Range and High-precision Current Measurement


CT6863-05 – AC/DC Current Sensor, 200 A AC/DC, ME15W terminal


Hioki pass-through AC/DC current sensors are best-in-class devices for use with power meters, Memory HiCorders and high performance oscilloscopes. The CT6863 is a DC to 500 kHz/200 A sensor, and this is ideal for capturing current signals from switching power supplies, inverters, power conditioners, etc.

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