Records transients at up to 24 µs

Transients are increasingly a problem in electrical grids. The PQI-DA smart offers the ability to measure these transients exactly down to 24 µs, allowing precise network analysis. Analysis with our device makes the grid not only more stable but also safer.

Fulfil the measurement standards of tomorrow today

Our fix installed all-rounder offers a wide range of measurement options that represent the standards of tomorrow, today. Thus, our PQI-DE power quality device already provides frequency measurement from 2 – 20 kHz. Consider buying one of our devices as investing in the solutions of the future.

Residual current measurement RCM to 40.96 kHz over 5 current channels

Residual current measurement has a wide range of applications. On the one hand, the measurement device can be used to substitute repeat insulation tests to DIN VDE 0150-100/A1; while in connection with a switch-off device it can also provide fire and material protection. The PQI-DE is the first device in the product portfolio that can do both.

IT security from the manufacturer with ISO 27001 certification

Certified security via User Rights Management (URM) and Role Based Access (RBAC) thanks to highly encrypted data transmission.
