The JRFS-xxxA-y and JRFS-xxxS-y Clamp-on Flexible Rogowski coils have been designed for accurate measurement of wide ranges of AC current, pulsed DC current or distorted waveforms. Coils with integrators are available by entering "JRFS-x Coil & Integrator" into the Search Store Box
- The coils feature tight windings that result in a very thin coil
- Applications
- Very high current monitoring
- DC ripple measurement
- Harmonics and transients monitoring
- Power monitoring & control systems
- Applicable in electronic watt-hour meter
- Features
- AC current probe utility by the Rogowski principle
- Flexible and lightweight
- Easy & quick installation on uninterruptible power line
- No danger from open-circuited secondary
- High secondary output voltage & precise linearity error
- Isolated plastic case recognized according to UL94-V0
