PQM-703 Power quality analyzer

PQM-703 is a technically advanced product that allows for comprehensive measurements of the quality of electricity, analysis and recording of power network parameters, for frequencies 50/60 Hz in accordance with European standard EN 50160.

Manufactory: SONEL S.A. (Poland).

Description

PQM-703 in relation to the PQM-702 has new functions like recording of transients with max. sampling frequency 10 MHz (rapid changes in voltage) and control signals. Minimal transient capturing time is 650 ns. It is intended for a very wide range of users who need to control the quality of power with a mobile device , which fulfills the requirements of a multi-sheet standard IEC 61000 for class A analyzers. This applies to measurement accuracy, measurement methods, and synchronization of time with a standard signal. The last condition is met with a built-in GPS module with an internal antenna. If the analyzer is installed inside, it is possible to use an additional antenna with a 10m-long wire. If the antenna is situated outside, GPS signal will be attainable without any problems and used for the synchronization of an internal clock.

Features

Power from the measured network
Designed for use in virtually all network types from 64 V to 760 V directly, with particular emphasis on measurements at low voltage poles, due to the ease of installation
Independent power supply makes it particularly suitable for measurements behind voltage transformers. It can also be used for measurements in DC voltage systems
Remote configuration and data transfer in real time using the built-in GSM modem
Anti-theft function – text message notification in case of position change – built-in GPS receiver
Real time clock synchronized using GPS protocol
