Automatic Transfer Switches (ATS) are essential devices used to ensure a continuous and stable power supply by automatically switching between the main power source and a backup source when a power failure or abnormal voltage occurs. They are widely used in residential, commercial, and industrial power systems to maintain uninterrupted operation during power outages.
Our ATS product line is divided into three categories: Switch-based ATS, Breaker-based ATS, and ATS Controllers.
Switch-based ATS offers fast transfer performance with a compact design, suitable for residential and light commercial applications.
Breaker-based ATS utilizes MCCBs or ACBs to provide enhanced protection, including overload and short-circuit protection, ideal for industrial and heavy-load environments.
ATS Controllers act as intelligent control modules that manage the transfer logic, monitoring, delay settings, and generator start/stop commands.
DERLICN ATS solutions provide multiple functions, including automatic and manual transfer, main/backup power monitoring, overload and short-circuit protection (breaker-based models), delay settings, generator control signals, real-time status indication, fault alarms, and optional smart features such as remote monitoring and communication capabilities. These functions ensure safe, stable, and uninterrupted power switching across various applications.
