The Sensor measures: AC Current

AO-S1 Is a High Accuracy Rogowski coil integrator, in a
compact shield aluminium alloy enclosure, powered directly from mains.

S1 can be combined with any model and size of AO-YTFC or AO-TFC Rogowski coils.
The availble values are: 0-5VDC, 0-5V peak, 4-20mA.
on request the imput value can be customize according to the application.
AO-S1 and Rogoswki coil is a very flexible sytem, suitable for high power load analysis,
impulsive current monitoring, DC ripple measurement,etc.
due to its specific features,flexible Rogowski coil is an extremly comfortable solution
for current measurement and can be used in a number of cases where traditionalcurrent
transducer is not the adequate solution.
