Automatic Transfer Switch

Static Transfer Switch or Automatic Transfer Switch is an automatic static switching equipment designed to transfer critical loads between two independent AC power sources without interruption or with a transfer time of less than a cycle (4ms).

Continuity of process control is critical across a vast range of industrial markets: Data Center and Server Rooms, Healthcare and Medical Equipment,  Pharmaceutical, Oil, Gas, and Petrochemical Industries, Chemical, Power Generation and Distribution, Semiconductor, Automotive, & Renewable Energy and Telecommunication and IT.

The microprocessor-controlled Automatic transfer switch or ATS constantly monitors the sources connected to the inputs; checks whether they remain within the current and frequency limits and decides if they are synchronized with each other. If the prioritized source is within the determined limits, the critical load is transferred over to the prioritized source. If the prioritized source is not within the determined limits, the load is then transferred to the other source which is within the determined limits.
