Hioki 3274 high-frequency current probes

Hioki 3274 high-frequency current probes are suitable for connection to oscilloscopes and Hioki waveform recorders. Applications include industrial electronics, inverters, electronic ballasts, switchmode power supplies, etc.

Users can select from a range of CT-style probes for frequencies to 100 MHz and currents to 500 A. There are four models to choose from: DC to 50 MHz (30 A); DC to 100 MHz (30 A); DC to 10 MHz (150 A); and DC to 2 MHz (500 A).

Features include insensitivity to external magnetic fields to 400 A/m, very small rise times and high signal-to-noise ratio. The Hioki probes can be powered from Hioki waveform recorders or from FET probe oscilloscope power supplies. In addition, the probes can also be powered from Hioki 3269 power supplies (four probes) or Hioki 3272 power supplies (two probes).
