INFORMATION

Description

QNA 500 is a modular power quality analyzer designed to measure and record the main electrical parameters and transient disturbances. The measurement is taken in true root mean square (TRMS), with 5 AC voltage inputs, 4 AC current inputs (via ... /5 A current transformers) and a leakage current input.

Applications

QNA 500 is designed to supervise the electric installation and problems relating to electric power quality, in order to control production processes and manage incidents. It integrates easily with SCADA applications and interacts with commercially available PLCs, and so can be part of more global data acquisition systems and report to users the information they require at any time. Its modularity and the addition of M-IO8 modules enable the user to also control energy consumption, states of switches or loads, send alarms, and even connect/disconnect loads according to configurable conditions.
When combined with CIRCUTOR PowerVision Plus software, the user can configure customised reports to assess the correct running of the electric installation, and can apply standards such as the EN-50160, event tables such as CBEMA, UNIPEDE or others. By automating this information, the user can view the most important data needed for the relevant analysis with just one click .
