The fix-installed power logger
PQI-DA smart
For measurement in industrial environments
PQI-DA smart
The PQI-DA smart is a voltage and power logger and fault recorder all in one. It has been developed for measurements on public grids, smart grids and in industrial environments up to 690V (L-L) measured voltage. The device can be used both as a power quality device and a measurement system to detect all the physical qualities of alternating current networks. This makes the device an appealing power quality all-rounder.

Records transients at up to 24 µs
Transients are increasingly a problem in electrical grids. The power logger 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.
Highly accurate electrical sensors available
Do you want to leave your measurement circuits to do their job? Then we have a cost-efficient solution for you! With the C40 feature, four power inputs for Rogowski coils are provided; with C44, four AC power inputs for mini current clamps. We have tested the C40 model’s ability to measure the current in Rogowski coils; measurement errors are very linear up to 19 kHz.
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-DA smart power logger already provides frequency measurement from 2 – 20 kHz. Consider buying one of our devices as investing in the solutions of the future.

Power quality monitoring with »PQI-DA smart« in combination with »I-Sense«
High-quality power quality monitoring with the option of quick and easy feeder current measurement helps to recognise trends at an early stage and enables countermeasures to be initiated at the right time.
High-precision transformer measurement with »PQI-DA smart«, »PQI-DE« or »PQI-LV«
- Measure voltage, current and power quality parameters at the transformer feed-in with a deviation of less than 0.1% in accordance with IEC61000-4-30 Class A Ed. 3 to evaluate the power quality via in accordance with EN50160 and IEC61000-2-2.
- Analysis of flicker, THD, harmonics (H2-H50), supraharmonics 2-20kHz, transients & PQ events with fault recording.
Measuring, Recording and Evaluating Outgoing Circuits With the »I-Sense« Feeder Current Feeder Measurement Technology
- Current measurement L1/ L2 / L3 / (N) with min. and max. values for up to 16 feeders.
- Simple connection possible using existing third-party devices, such as switching pannels with intelligent transducers.
Reporting – to the point with the »WebPQ®« analysis software
- »WebPQ®« software for quick and easy evaluation of power quality and feeder current using intuitive, configurable reports.
