» General description
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:
• the standard output carring out the instantaneous value, with 1 or 3 VRMS full scale.
• an optional DC output carring out the RMS value of the measured current.
The available values are: 0÷20 mA, 4÷20 mA, 0÷10 VDC.
On request the input value can be customized according to the application.
RPS50 and a Rogowski current transducer is a very flexible system, suitable for high power load analysis, impulsive
current monitoring, DC ripple measurement, etc.
Due to its specific features, flexible Rogowski coil is an extremely comfortable solution for current measurement and can
be used in a number of cases where traditional current transducer is not the adequate solution.

Since the Rogowski coil output is proportional to
the frequency of the measured current, the signal
equalization ensure a linear response on a wide
frequency range. RPS50 allows to use coils on different
electrical network frequencies, keeping the same
output level over the frequencies.
The 90° correction give the correct phase for power
and energy measurements. RPS50 can by used in
conjunction with power meters allowing to take
advantage of the great measuring linearity of the
Rogowski coils.
The availability of different selectable scales give the
possibility to use the same coil on a extremely wide
range of current values.
The configuration and calibration controls accessible
from the front panel increase the flexibility of the
module and make it more confortable in use
