Description

Technical Field

[0001] This utility model relates to the field of transfer switch technology, specifically a dual-power automatic transfer switch. Background Technology

[0002] Currently, automatic transfer switches (ATS), as the name suggests, automatically connect to a backup power source when a power outage occurs, ensuring uninterrupted operation. Simply put, the purpose of an ATS is to have one main power supply and one backup power supply. When the main power supply fails or is interrupted, the ATS automatically switches to the backup power source, allowing equipment to continue operating normally. Many industries and departments have extremely high requirements for power supply reliability. To ensure continuous power supply, ATS are used in many important situations to power electrical appliances. As an essential device for power switching, the technical performance requirements for ATS are becoming increasingly stringent.
