Mô tả
RPS51 is a multiscale Rogowski coil integrator, in a compact DIN rail enclosure, powered directly from the mains.
An integrator is essential to equalize and shift by 90° the output signal from the Rogowski coils. It consists of an active electronic
circuit with negligible offset and a good linearity. RPS51 can be combined with any model and size of MFC series Rogowski coil.
The integrator is provided with a push button for an easy scale selection. Up to four input scales are available: 100, 500, 1000, 5000 A.
This provides a wide range of applications witgh a single coil and RPS51.
RPS51 and a 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 PMD’s.
