The Power Quality Analyser (PQA) is a device to measure and check the quality of the power supply and
is manufactured as an industrial grade DIN rail device. The compact E-Line design enables installation
in restricted spaces in electrical distributor boxes. The extensive measurement options enable an
analysis of any disturbances with cyclic/event-oriented data capture and automatic messaging if
a measured variable is outside the tolerance limits. The integrated RS-485 interface is available in the S-Bus/Modbus and enables
communication with a Saia PCD® controller or other master devices. Programming is also very efficient and fast using a comprehensive
FBox library with web templates.
