High-end class A PQ analyzer and data logger for industrial application, 0.2S sub-meter, CATIII/300V, color graphic display option, optional inputs and outputs, din rail mounted, 6 modules

The ARTIQ 235 is specially designed for high-end energy management systems and to record and analyze the power quality in industrial and residential power systems. This high-end instrument with various communication options is suitable for a wide spectrum of automation tasks in modern buildings, smart factory and smart grids, to monitor distributed power generation and remote supervision of the infrastructure and also to monitor a remote load management. With a proper firmware module it can be used to collect and store data from attached slave units.

It can optionally monitor power quality (with PQ-A module - inter-harmonics, flicker, voltage events), record transients (with GO module) and the ripple control signals (RCS module).
