Why Upgrade Now?
Power quality measurement has moved on considerably.
Today's electrical networks contain far more power electronics, from solar inverters and EV charging infrastructure to variable-speed drives and other switched loads.
That means engineers increasingly need to investigate disturbances beyond traditional power quality measurements.
A. Eberle highlights disturbance frequencies of 16–18 kHz from solar inverters and 10–80 kHz from EV charging stations as examples of the higher-frequency challenges that can occur in modern networks.
If you're still working with an older analyser, upgrading isn't simply about having newer equipment.
It's about having the measurement capability to investigate today's electrical networks.
More Measurement. More Insight.
The latest PQ-Box generation offers a significant step forward from older instruments.
Depending on the model, benefits include:
- Measurement into the supraharmonic frequency range
- Significantly more simultaneously calculated measurement values
- Larger graphical colour displays
- WLAN connectivity
- Greater storage capacity
- Smartphone operation and live data viewing
- Advanced transient recording
- Modern power quality standards compliance
A. Eberle states that its current PQ-Box 50, PQ-Box 200, PQ-Box 200 and PQ-Box 300 generation complies with IEC 61000-4-30 Edition 4 (2026), Class A, while the older PQ-Box 100 was developed to an earlier edition of the standard.
For engineers carrying out increasingly complex power quality investigations, those additional capabilities can make a real difference.
Modern power quality analysis with easier access to live measurement data.

Modern power electronic loads and generators are creating disturbances at increasingly higher frequencies.
The latest PQ-Box generation provides greater visibility into these higher-frequency phenomena, including the supraharmonic frequency range.
This can be particularly valuable when investigating modern equipment such as solar inverters, EV charging infrastructure and other power electronic loads.
Greater visibility into higher-frequency power quality disturbances.

Not sure which one you need?
That's where Acutest Direct can help.
We can talk through the measurements you're currently making, the problems you're trying to diagnose and the capabilities you need from your next power quality analyser.
Capture Fast Switching Transients
Fast switching transients are not uncommon in industrial applications, but capturing these extremely fast events requires a high sampling frequency and a wide measurement range.
The PQ-Box 200 is specifically designed for this type of investigation, sampling signals at up to 4 MHz.
Investigate fast electrical events that require high-speed transient recording.
Trading In Your Old Analyser Is Simple
A. Eberle has made the process straightforward.
And importantly, you don't need to send your old instrument back.
To take part, you'll need to provide photographic evidence that the old analyser has been rendered unusable, together with a photograph of its nameplate.
Three Simple Steps
- Choose your new eligible PQ-Box and place your order, stating that you are taking part in the trade-in promotion.
- Provide the required photographs showing proof that your old analyser has been rendered unusable, together with a photograph of its nameplate.
- Receive your trade-in discount on the eligible new PQ-Box.
Your old instrument can be a PQ-Box 100 or a comparable three-phase power quality analyser from another manufacturer, making this a particularly interesting opportunity if you've been considering switching to A. Eberle.
