Rockwell Automation has announced it has purchased the assets of SoftSwitching Technologies, a leading provider of industrial power quality detection and protection systems, located in Middleton. SoftSwitching Technologies' solutions improve uptime in manufacturing production by identifying and correcting brief power disruptions called 'voltage sags.' Typically, voltage sags can cause computerised machinery to go off-line, precision instruments to fail, and control systems to shut down. These problems can be extremely costly for customers, particularly in the semiconductor, automotive, food, beverage and pharmaceutical industries.
