Q What is an Automatic Transfer Switch (ATS)? An ATS is a device that automatically transfers the load between two power sources, such as the main utility power and a backup generator, to ensure continuous power supply when one source fails. QHow does an ATS work? The ATS continuously monitors both power sources. When the main power fails or becomes unstable, the ATS automatically switches the load to the backup power source. When the main power is restored, the ATS automatically transfers the load back to the main supply. Q What are the main components of an ATS? Controller: Monitors voltage and frequency of both power sources. Switching mechanism: Executes the transfer between sources. Mechanical interlock: Prevents both sources from being connected at the same time. Display or indicator: Shows the current operation status. QWhat are the common types of ATS? Automatic Type: Performs automatic detection and transfer. Manual Type: Requires manual operation for source transfer. CB Type (Circuit Breaker Type): With short-circuit protection. PC Type (Power Contactor Type): Without short-circuit protection, suitable for general loads. QWhere is an ATS commonly used? ATS units are widely used in: Hospitals and data centers Telecommunication and security systems Industrial automation Commercial and residential buildings Emergency lighting and fire control systems
QWhat are the benefits of using an ATS? Ensures continuous power supply Improves system reliability and safety Reduces downtime during power failures Allows automatic control without human intervention QHow long does the power transfer take? Transfer time depends on the ATS type and design, typically within 1-5 seconds for standard systems. High-speed or UPS-integrated systems can achieve seamless transfer. QWhat is the difference between "PC type" and "CB type" ATS? Type Description Application PC Type Uses contactors for switching; cannot break short-circuit current General load control CB Type Uses circuit breakers; has protection and isolation functions Critical or high-power systems Q Can the ATS be customized? Yes. Voltage rating, current capacity, transfer delay, and control logic can be customized to meet different application requirements. QDoes the ATS require regular maintenance? Yes. Regular inspection is recommended to ensure reliable performance - check connections, clean contacts, and test switching operation periodically.
