1. Scope of Application: This technical specification is applicable to electronic controllers for automatic transfer switches (ATSE) that comply with the GB/T14048.11 standard. The controller is used to detect and monitor the status of the power supply. When the power supply deviates from the set normal state, it can automatically issue action commands to switch the ATSE main body to the normal working power supply side. This technical specification specifies the terms and definitions, characteristics, performance requirements, and test methods of controllers. The following documents are essential for the application of this technical specification. For dated references, only the version with the date indicated applies to this technical specification. For undated references, the latest version (including all modification orders) applies to this technical specification.
