Experience the simplicity of measurement with IsoBlock V-3P, a 3-phase voltage monitoring module with easy plug-and-play usability. It’s designed for engineers developing systems where high-voltage signals need to be monitored with accuracy and reliability. The IsoBlock V-3P covers multiple ranges from 150VAC to 1000VAC, with up to 100kHz bandwidth and as high as 0.1% accuracy.  

Moreover, depending on the software configuration, the IsoBlock V-3P outputs phase-to-phase voltages for Delta configuration, or phase to-neutral for Wye configurations. Elevate your high-voltage signal monitoring capabilities with the IsoBlock V-3P, where accuracy meets convenience in a single innovative device.

Differential Divider Network

With an anti-aliasing filter on its output. It generates a 7VAC scaled down version of the input terminals.


Isolated References

The input of each specific IsoBlock channel has its own isolated reference and can be configured to suit user needs. One IsoBlock V-3P replaces 3 or 4 differential sensors depending on configuration, and only requires one cable for all four signals. It simplifies wiring while increasing channel densities, while delivering high performance for a low cost.

Plug-And-Play Usability

The IsoBlock V-3P's plug-and-play usability, enables easy re-configuration and speeds the pace of industrial product development and deployment.

Flux Gate Methodology

The IsoBlock I-FG-4C uses Flux-Gate methodology to measure the current flowing through the input conductor. This technique works by placing a toroid with a high number of turns (secondary) around the input current path (primary), while a close-loop circuitry controls the current through the secondary to null out the magnetic field inside the toroid. The input current is then obtained by multiplying the current from the control circuitry by the number of turns of the secondary. This is followed by an anti-aliasing filter and a conditioning stage to output a ±5V signal.
