The IsoCap V-4c module has been designed to provide high-quality isolated differential voltage measurements for aplications requiring scaling of high voltages, as well as superior isolation.
Each IsoCap V-4c unit hosts four separate isolated channels, each of which can be connected to separate measurement sources while provpiding a range of functional coverage up to 1500V. The input of each specific IsoCap channel has its own isolated reference, and can be configured to suit user needs. All processed signals output from the IsoCap unit are referenced in respect to the ground channel of the user's data acquisition system.
Designs its IsoCap V-4c modules with consideration for user great flexibility, high channel density and low power consumption.

The IsoCap V module is designed to isolate and scale down high voltages found in industrial enviroments. The end result is a signal ready to connect to any data acquisition system, while galvanically isolating the source from it.
Each channel of the IsoCap module has a galvanic isolation from the input to the output that can eliminate large common mode voltages. In addition to that, each channel also has a protection stage at the input that guards it from surges.
Following the input surge protection stage, there is an amplification stage that brings the input signal to a ±10V range. This signal is modulated into a magnetic field, and then transferred across a galvanic barrier. A demodulating stage recovers the original signal, followed by an anti-aliasing filter and a conditioning stage to output a ±10V differential pair. The figure below shows a block diagram of the process decribed above.
The isolation barrier of every device is tested with a 5 second partial discharge of 1800V for 5 seconds, with a detection threshold of 150pC.
Withstanding common mode surge voltage is 2 seconds half sinewave.
Withstanding differential mode surge voltage is 4 seconds half sinewave.
