Product description
SZR units are automatic mains transfer switches that enable fast and reliable switching between two 230 V AC power sources. In the event of a failure of the main power source, the system immediately switches to the backup power supply, with a switching time not exceeding 40 ms. Industrial SZR mains transfer switches are equipped with comprehensive load protection and the option to manually disconnect a selected power circuit. LED indicators allow monitoring of voltage presence at the inputs and output, whilst mounting on a TS35 DIN rail facilitates integration with existing installations. Thanks to their functionality, automatic transfer switch (ATS) units are used in installations requiring uninterrupted operation, such as telecommunications, power supply and industrial systems.
