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 factories and smart grids, to monitor distributed power generation and remote supervision of the infrastructure and also to monitor remote load management. With a proper firmware module, it can be used to collect and store data from the 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).
