Selecting the Right ATS for Your Needs

It is a mistake to believe that every ATS is created equal. The features, functions, and reliability of these critical devices can vary from manufacturer to manufacturer. Choosing the right one for your needs boils down to knowing what questions to ask. If you choose the wrong ATS, you can suffer equipment malfunctions and disruptions in your operations. Thus, it is worth spending extra time and working closely with an EGSA certified technician to identify the best ATS for your specific needs.

How Does It Work?

There are four main types of ATS operation. The first is open-transition, which requires the ATS to open the source before it connects. This process results in a short delay of less than a second that helps protect people from injury and devices from damage.

Of course, this delay is unsuitable for data center operators, healthcare providers, etc., where faster, closed-transition ATS options are better suited. Closed transition ATS doesn’t need to open before making the connection because it can operate simultaneously with the primary power source. This allows for a seamless transition when the primary source goes down and when it comes back online.

Another option are soft load power transfer switches. These synchronize both power sources and connect them in parallel. This arrangement is ideal for minimizing voltage and frequency transients that can damage sensitive equipment.

Finally there are bypass isolation automatic transfer switches. These complex systems are also highly capable, which is why they are typically used in medical and other critical operations, such as air traffic control, life support systems, etc. This arrangement allows for smooth transition between primary and secondary sources, and it also allows isolation of the ATS for testing purposes without causing any disruption to mission critical equipment.

What Is the Continuous Current Rating?

It is important to know how long the average power outage in your area can be. This can help you identify how long your ATS should be able to supply you with continuous power. Whether it is 3, 5, or 25 hours, you need an ATS that can deliver the required amps for as long as you may need it.

What Is the Voltage?

An ATS can be connected to unsynchronized power sources. This can give you considerable flexibility, but it also means that you have to choose the right ATS based on the equipment you need to supply power to. Always confirm that the ATS will deliver whether you need 120, 240, 600 volts at 50 or 60 hertz.
