Mounted Power Quality Analyser  – Overview

The Mounted Power Quality Analyser is a stationary meter.  It is designed to be mounted on a DIN rail and can be mounted on a wall in a cabinet. It has a modular design that allows the expansion of the meter. It measures and records power supply parameters for compliance with standards and applicable laws. It can verify the preset terms of a power sale or purchase contract. It is manufactured in class A.  The instrument allows measurements in 50 Hz, 60 Hz and 400 Hz networks.
