The Sonel PQM-711 versatile power quality analyser for remote analysis in the A class is a device suitable for use on all types of networks with a rated voltage range from 110 V to 1000 V either directly or indirectly through transformers.

Based on advanced technology, the Sonel PQM-711 power quality analyser allows comprehensive measurement, analysis and recording of 50/60 Hz power network parameters and power quality according to the European standard EN 50160.

Sonel PQM-711 Pro comes with 4 pcs of F-3A flexible current clamps.

Capabilities

Sonel PQM-711 has a built-in GPS receiver ensuring real time clock accuracy and an integrated 4G LTE GSM modem that facilitates remote analyzer operation. Furthermore, Sonel PQM-711 is also equipped with a transient recorder (sampling frequency 10 MHz, voltage range up to ±8000 V).

An additional trump card of the analyzer is the built-in Wi-Fi communication module, providing a number of advantages: no restrictions on file transfer, no data transfer costs, use of local wireless infrastructure... This gives the user the opportunity to adapt to the conditions prevailing on the site. They can supervise measurements from a convenient location – for example, an area without electromagnetic interference – using a laptop, smartphone or tablet.
