SIMON PQ is a modular analyzer of power quality. In the basic package it is intended for continuous monitoring of four voltages and currents (in three phase AC networks). The number of monitored currents can be extended up to the maximum of 24 multiplexed inputs. The device shares many features and parameters with its built-in predecessor SMPQ. Compared to other SIMON class of instruments it can additionally evaluate flicker severity indexes, inter-harmonics and evaluates power quality according to EN 50160. Its ultra compact case and IP-65 case is making this monitor an ideal choice for measurements in rough space limited environments.

This instrument will be released during the Hannover Messe 2010 fair.

Features

• 4 voltage inputs, 4-24 current inputs
• logger is supplied from any measured voltage input; optionally voltage cable with additional 2 croco-clips for independent power supply connection
• optional voltage cable for a wall socket mains measurement
• continuous measurement of voltage, power quality processing (EN 50160, harmonics, flicker, sags, swells, event oscillograms etc.)
• continuous measurement of currents/power/energy for up to 4 current inputs; for more than 4 current inputs processed non-continuous (switched) measurement
• logger setting and data download via an USB interface (through the voltage connector); optional wireless Wifi inteface
• record interval configurable from 200 ms up to 2 hours
• internal memory for archives with capacity of 512 Mb
• record capacity for months of unattended monitoring campaigns
• acquisition and analysis of the archives in ENVIS software suite (basic version available freely)
