Class S power quality analyser logging up to 1100 parameters
The APQM-700 records up to 1100 network parameters in accordance with class S of IEC 61000-4-30, measures voltages up to 760 V and currents up to 6 kA, and keeps working in rain and at -20 °C thanks to its IP65 housing and internal heater.
Advantages
Massive parameter logging
Up to 1100 parameters with average, minimum, maximum and instantaneous values, including powers by Budeanu and IEEE 1459, energies, harmonics up to the 40th, THD, flicker and unbalance.
Four voltage and four current inputs
It measures L1, L2, L3 and N up to 760 V, works with voltage transformers, and measures currents up to 6 kA depending on the clamp, with physical measurement of the neutral current.
Built for the outdoors
IP65 ingress protection allows operation in rain, snow and high humidity, and the built-in heater keeps measurements stable down to -20 °C.
Autonomy during power failures
The internal battery keeps the recording running for at least 6 hours if the supply fails, without losing data on the memory card.
Events with waveforms
It detects events in real time and stores waveforms and half-period RMS graphs to locate the origin of disturbances.
Applications
- Recording of load parameters in industry and maintenance services.
- Four-quadrant power analysis in wind and solar farms.
- Supply quality audits in accordance with EN 50160.
- Diagnostics of disturbances in substations and LV switchboards.
About the product
The APQM-700 is a compact analyser of 200 × 180 × 77 mm and about 1.6 kg, powered from the mains at 100…415 V AC or 140…415 V DC, which logs onto a removable 2 GB microSD card expandable to 32 GB; data is downloaded over USB and analysed in the Amperis Analysis software, with reports according to EN 50160.

Frequently asked questions
Which standards does the APQM-700 follow?
All parameters are recorded in accordance with class S of IEC 61000-4-30, and the software generates reports against EN 50160 and user-defined reference conditions.
Does it work outdoors?
Yes. The IP65 housing withstands rain, snow and high humidity, and the internal heater keeps operation stable from -20 °C up to +55 °C.
What happens during a power cut?
The internal rechargeable battery maintains the recording for a minimum of 6 hours, so no measurement campaign is lost.
How is the data retrieved?
From the removable 2 GB memory card over a USB connection or an external reader, then analysed with the free Amperis Analysis software.
Which currents can it measure?
Up to 6 kA depending on the clamps used, on the three phases and the neutral, whose current is measured physically on a fourth input.
