200 AMP ASCO Transfer Switch ATS, 2 Pole NEMA3R 240V ASCO ATS Series 185 185A2200F4M (Replaces ASCO Series 165 165A2200F3F)

Although a diesel generator may seem like the cornerstone to your backup electricity solution, your standby system will never be complete without an Automatic ATS Transfer Switch.

An Series 185 Transfer switch combines highest safety standards and cutting edge technology to Automatic provide you with uninterrupted power. To achieve its goal, the ATS works as follows:

  1. In the event of your utility power failure (Normal Source), the series 185 Automatic ATS Transfer Switch orders the standby generator (Emergency Source) to start and warm up in preparation to accepting the load.
  2. In bare seconds, or based on your desired configuration, the ATS controller triggers the transfer switch which within milliseconds safely switches the load from the Normal source to the Emergency source.
  3. In the background, the ATS controller continues monitoring both the availability and the stability parameters of the Normal Source. Upon observing and verifying that acceptable parameters are present and maintained for a preset time window, the ATS controller will then trigger the switching mechanism again to transfer the load from the standby generator to the Utility power. Also within milliseconds.
  4. To maximize the lifespan of the engine, the transfer switch will order it first into a cool down period of time before ordering it to shut down completely.
  5. Now that utility power has been restored, the standby generator will remain on Standby mode while the ATS controller once again enters its monitoring function and remains prepared to activate again in a matter of seconds.
