DIN-Rail Power supplies are found in almost every industrial process control system. During the conversion from AC mains to lower DC power outputs, switch-mode power supplies produce high voltages and currents that, if incorrectly designed, may cause sparks and generate excess heat through inefficient design topologies.
ABB technology is being used to build the world’s largest desalination plant in Taweelah, Abu Dhabi, United Arab Emirates. The USD 500 million development will have the capacity to process over 900,000 cubic metres of seawater per day, enough to meet the demands of over 350,000 households.
The demand for flexible, modular systems is shaping the world of automation, control and machine building. Decentralisation of system components has proven to be an important factor in this growing trend. It speeds up the system planning process, simplifies installation and maintenance, and facilitates future expansion.
Mico Pro is Murrelektronik's innovative 24 VDC current monitoring system. The modular design makes it possible to create systems that fit any 12/24V application perfectly – which adds value by creating a cost-benefit ratio that saves space in the control cabinet. Murrelektronik's patented tripping behaviour ensures maximum machine availability.
Selective channel monitoring is due to a phenomenon that only appeared with the market introduction of electronically controlled power supplies. This story describes what this is all about and how Murrelektronik solved it.
