HOW WELL DO YOU REALLY KNOW YOUR NETWORK?

Even in modern grids powered by renewables, small changes can lead to big problems.

You don’t need a major fault to see disruption: just a few seconds of harmonics, imbalance or flicker can affect how your equipment performs.

A voltage dip can cause a shutdown.
Crossing a threshold can mean unexpected costs.

PQM4000 records and logs what’s important.
It monitors average energy use.
And it gives you a clear daily chart to track any breaches of your contractual limits.

PQM4000 is the Class A certified power analyser designed for real-world conditions:
LV/MV switchboards, systems with inverters, mixed loads, hybrid networks and microgrids — that’s where PQM4000 belongs.
It turns raw data into actionable insights.
It does more than just record: it connects, interprets, anticipates.

PQM4000 is your front line of monitoring

• IEC/EN 61000-4-30 Class A compliance
• Power quality analysis according to EN 50160 and IEEE 519
• Harmonic analysis up to the 63rd order
• Simultaneous sampling on 9 channels at 1024 samples/cycle
• Event detection with waveform capture and half-cycle RMS values
• Integrated GPS, Ethernet, RS485, Wi-Fi, USB
• Data export in PQDIF and CSV formats

See everything, In real time?

With PQM4000, monitoring is continuous — and certified.
You get real-time insight on every key parameter: voltage, current, frequency, harmonics — all in full compliance with IEC 61000-4-30:2015.
For Ethernet communication, alongside a fast and intuitive web interface, you have PQM-Tool: a dedicated software tool designed for direct, in-depth access to all the data measured by the device.

For analysing logged events and parameters across all versions, there’s PQM-Analyzer: a complete historical view, automated reports, standards compliance verification and data summaries — all in one place.
