Automatic transfer switches for a smoother transition of power
05 October 2015
ABB has introduced its latest generation of Automatic Transfer Switches (ATSs) for critical power applications that require a constant and reliable power supply.
An ATS ensures the safe, reliable, secure and user-friendly transfer of loads from the primary network to a standby generator or a second power supply. Used widely in critical power applications such as telecommunications, healthcare, utilities, commercial buildings and data centres as well as buildings that are fitted with fire safety systems, the range includes manual and automatic switches, controllers and accessories for motors, resistive loads, mixed loads and off load applications.
ABB is now reaching out to the market with its latest generation ATSs in enclosures, which are assembled and tested in the UK for applications rated from 40 to 1,600A. The IP65 enclosure protects against dust and water ingress and its design allows significant space for cabling so that installers will find it easy to terminate oversized cables.
Basic ATSs monitor the loss of supply and switch to and from backup power. Higher levels of control include timer functions, dead pan and back switching, generator start / stop switching, energy metering and load shedding capabilities, as well as communication with a Building Management System (BMS).
“Critical applications require a constant and reliable power supply to keep fundamental services running and prevent serious consequences due to interruption or absence from the electrical grid," says Len McGanity, product manager for ABB Breakers and Switches in the UK. "This need is even more pronounced in everyday life because of the increasing demand placed on the grid. That’s why ABB wants to let the market know about our range of enclosed change-over and auto transfer switches.”
