Rack-mount transfer switches are devices that switch electrical loads between primary and backup power sources, ensuring uninterrupted operation of critical equipment. Automatic transfer switches (ATS) detect outages and switch seamlessly, while static transfer switches (STS) use solid-state technology for ultra-fast transfers. Hybrid and other specialized designs provide tailored switching solutions for various needs. Accessories like communication modules and mounting kits enhance functionality. These switches play a vital role in data centers and industrial systems, offering protection against power interruptions, optimizing energy management, and ensuring continuous equipment operation.
