Fluke i50S, AC Scope Current Probe, 50MHZ
  • Designed for use with bench oscilloscopes, the i50s Current Probe offers an ergonomic, robust and high performing solution for the measurement of DC and AC currents up to 50 MHz. With a permanent nominal current of 30 A RMS and a measuring capacity of 50 A for 10 s, as well as exceptional immunity to high common mode voltages (dv/dt = 5 kV/_s,) amplitude = 1,5 kV, error < 0,05% of IPN), the i50s considerably widens the possibilities of accurate measurement of commutation currents.
