What is Automatic Transfer Switch?

An automatic transfer switch (ATS) is a device that automatically transfers a power supply from its primary source to a backup source when it senses a failure or outage in the primary source. When a failure occurs in a primary power system, the ATS invokes a standby power source, such as an uninterruptable power supply. An ATS can also start up more long-term backup power systems, such as local diesel generators, to run electric equipment until utility power is restored.

Since the ATS is connected to both primary and backup power sources, automatic transfer switch serves as an intermediary between equipment and the power supplies, acting as an electrical relay. An ATS can also act as a redundant, rack-mounted power supply for equipment that is connected to a power source with only one cord. This article mainly introduces automatic transfer switch.

Advantages of Automatic Transfer Switch:

A transfer switch does a lot for your business, increasing assurance and productivity. When you choose the right switch to meet your needs, you'll gain.

• Power reliability. If for any reason at all you lose access to power, your business stops dead in its tracks. And while a generator can mitigate this a bit, without a transfer switch you have to manually connect your generator to the operations you wish to restore. This chore not only eats up loads of time, resulting in downtime, it also limits the function of your generator.
• Safety. Handling any source of power at all can yield detrimental results. Employees can be harmed by a sudden outage, and handling a manual generator hookup can be disastrous—especially in the dark! A transfer switch handles all of your needs all on its own, removing the dangers associated with an outage entirely.
• Simplified operations. Upon the installation of your automatic transfer switch, specific operations are chosen to be automatically powered. This can be everything from your lights, to HVAC systems, industrial equipment, or even refrigerators. This process drastically simplifies restoring power and improves the function of your generator as well.
