Rogowski coil current probe

For the first time in the industry, a total of 46 models have been added to the lineup with a frequency of 100 MHz, ultra-fine Φ1 mm, and high temperature of 150º!

Features

By selecting the coil wire diameter and coil length, it can be used for various current measurement targets from narrow parts such as between IC leads to large bus bars (bus bars).

Range of application

Switching current waveform and pulse response characteristics of power devices

Current measurements of inverter system

AC current measurements (at large DC offset)

Impulse high current measurements

Bus Bar high current measurements
