A Guide to Selecting The Right Automatic Transfer Switch

 Automatic Transfer Switch helps transfer the load from utility power to backup or secondary power source when the power is gone. Multiple factors and requirements determine various types of Automatic Transfer Switch available.

There are several types of modes in which these ATS work-

  •  Open-transition transfer devices- These switches work by opening the connected source before connecting to the new  one. 

  • Fast-closed-transition transfer- These switches work parallelly; one source is disconnected when the two are working.

  • Soft closed transition- they synchronize the sources while they transfer the live sources and connect them with the help of a ramp load impulse to the backup power source.

  • Sub-cycle transfer- the transfer of power from one source to another often happens within a minimal time difference, causing a slight interruption.

 

 

Apart from the types of ATS, there are several factors you should keep in mind while selecting a perfect ATS.

  • Continuous Current Rating- an efficient automatic transfer switch supplies maximum current for three to four hours.

  • Types of load: based on your requirement, it is necessary to choose the type of load an ATS will handle. There are various system loads: Total system load, restrictive loads motor, incandescent lamp, and electric discharge lamp loads

  • Voltage rating: the automatic transfer switch should be able to handle increased voltage stress. AC system voltage ratings are 120, 208, 240, 480, 600 volts, and the standard frequency is 50 to 60 Hz.

  • Choose the right supplier: always choose a reliable source of your supplies. Netrack is a transfer switch manufacturer, providing you a range of rack accessories, including an automatic transfer switch. You can choose according to your need.


There are the following types of switches to choose from-

  • Standard switches: they are ATS installed with their sub-panel. People don’t prefer using these switches now as they are completely outdated now.

  • Load Centers: the ATS and sub-panel are in the same circuit. These switches are meant for small houses whose voltage usage is not that high.

  • Service Disconnect: these switches are suited for large generators. They are the most costly among the three but most effective and capable.

 

With all these points in your head, you can easily choose Automatic Transfer Switch to choose among the many choices you have. It is always better to take advice from an expert.
