Deskripsyon
RPS50 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. RPS50 can be combined with any model and size of MFC150 Rogowski coils. The module is available in the standard configuration with one of the 3 following full scales:
0.5 – 2.5 – 10 kA or 2.5 – 10 – 50 kA or 10 – 50 – 250 kA.
Two different outputs are available.
RPS50 and a Rogowski current transducer is a very flexible system, suitable for high power load analysis, impulsive current monitoring, DC ripple measurement, etc.
