DWQA QuestionsCategory: ATS SwitchWhat Is the Difference Between a Manual Transfer Switch and an ATS?

When it comes to emergency power systems, one key component is the transfer switch. This switch is responsible for transferring power from the main source to the emergency source when needed. There are two main types of transfer switches; Manual and Automatic. An automatic transfer switch (ATS) ensures a seamless transition between the primary power source and the emergency or auxiliary power. Unlike manual transfer switches, ATS systems do not require manual intervention to switch power sources.  

Why Is an ATS important?

ATS is important in sectors where a constant, uninterrupted supply of power is required. This may not be a critical value in residential districts, where a few seconds of manually turning on the emergency power won’t harm you. However, it’s critical in the following scenarios:  


In the medical sector, an uninterrupted power supply is vital for the operation of life-saving equipment. Hospitals often have multiple emergency generators on standby, but a delay in switching to emergency power could put lives at risk. An ATS ensures that the transition is seamless, so patients and medical staff may not even notice the loss of primary power.  

Industrial Sectors

Various industrial sectors like factories and oil derricks perform countless mechanical operations that require uninterrupted power.  If a vital process like a product assembly is halted even for a few seconds, the entire production line could be jeopardized. That’s why automatic transfer switches are irreplaceable in this case.   

Data Centers 

For data centers, maintaining a constant power supply is crucial to prevent data loss. Even a short delay in switching to emergency power can result in the loss of critical data. An ATS helps prevent such scenarios by ensuring an immediate transition to backup power.  

Final Words

The beauty of purchasing from Precision Industries is the unlimited customization. Some of our generators come with an ATS built-in, while others can be integrated with an APS for an additional cost. That way, those who don’t heavily rely on an ATS won’t pay a forced extra cost for a feature they won’t need. Alternatively, those who need it will find many options to keep their emergency power supply uninterrupted.  Visit our official website at PI Dubai to have an idea of what we have to offer, and contact us if you have any questions.
