The eXpertPRO DIN series compact intelligent electronic device (IED) is a DIN Rail power quality analyser with a small form factor design, the eXpertPRO DIN EM235 DIN-rail combines metering, power quality and control input/output functions that provide an advanced solution for substation, industrial automation and commercial energy management applications. Incorporating a unique collection of powerful features commonly found in numerous specialised measurements and recording equipment utilised in substation and industrial environments. Although the device is primarily designed as an inexpensive add-on to expand the capabilities of the existing utility substation protection equipment, it is well suited for a wide range of industrial and commercial applications with high input currents whenever extensive power quality monitoring is required.
