Multi-Scale Rogowski Coil Integrator RPS51 with 1 A Output
Multi-Scale Rogowski Coil Integrator RPS51 with 1 A Output

The RPS51 is a multiscale Rogowski coil integrator housed in a compact DIN rail enclosure, powered directly from the mains.
An integrator is required to equalize and shift the output signal from Rogowski coils by 90°.
It consists of an active electronic circuit with negligible offset and good linearity. The RPS51 can be combined with any model and size of MFC series Rogowski coils.
The integrator is equipped with a push-button for easy scale selection. Up to four input scales are available: 100, 500, 1000, 5000 A.
This allows a wide range of applications with a single coil and RPS51.
The RPS51 and Rogowski current transducer is a very flexible system suitable for high power load analysis, impulsive current monitoring, DC ripple measurement, etc.
Ideal solution for standard 1 A input PMDs.
