MFC150-UI
UL 2808 Ø8 mm flexible Rogowski coil
Certifications

Highlights
  • Suitable to measure currents from mA to hundreds of kA
  • High linearity
  • Wide dynamic range
  • Very useful with large size or awkward shaped conductors or in places with limited access
  • No danger from open-circuited secondary
  • Not damaged by large overloads
  • Non-intrusive, no power drawn from the main
  • Thanks to its light weight, it can be changed on the measured conductor
  • Totally shielded
  • UL 2808 certified

Applications
  • Measuring devices, lab instrumentation
  • Power monitoring & control systems
  • DC ripple measurement
  • Harmonics and transients monitoring
  • Very high current monitoring
