ATS panels (or automatic transfer switch panels) are used in combination with standby generators to automate the switch between the mains power source and a generator in a blackout. An ATS panel ensures that you do not have to manually switch to an alternative power supply, such as a backup generator in the event of a power outage. An ATS will automatically switch to another power and an ATS panel ensures that a generator doesn’t require manual operation. When combined with a UPS (Uninterruptible Power Supplies) there will be a seamless supply of power as the UPS will bridge the gap in power whilst the generator starts up, reducing the risk of data loss, damage to electrical equipment, or any disruption to a business or facility. Without a UPS, there will be approx a 15 second delay in power as the generator starts up. 

The ATS panel monitors the incoming AC mains supply so that, should there be a blackout, the electrical load is transferred to the standby generator. When the mains power is restored, the ATS transfer switch then returns the building back to the mains supply, and shuts down the backup generator. 

Using an Automatic Transfer Panel for Safety Reasons

An automatic transfer switch or manual transfer panel is installed as part of any generator project where there is a mains supply.

The benefit of an automatic transfer panel system over a manual system is the ATS panel moves the electrical load without any manual process, reducing downtime. In the event of a power outage the transfer switch automatically switches its incoming power supply from the mains to the generator, triggering the generator to start up. The generator is ready to take load within approx. 15 seconds.

Without ATS switches, organisations would have to manually change over from mains to the generator and therefore suffer a longer break in electricity and depend on personnel being available to carry out this task. An automatic transfer switch panel will eliminate this need for a manual change.

    What Is the Difference Between ATS and AMF Panels?

    Automatic Transfer Switches (ATS) and Automatic Mains Failure (AMF) panels both switch an electrical load from normal supply to a standby generator supply, and back to the mains when required and are in effect just different terminology for the same thing. To find out more about AMF panels and how they work, read our blog which further explores all AMF-related topics.
