Automatic transfer switches (ATS) for diesel generators help transfer the load between the generator supply and the mains supply. Using automatic transfer switches means power is transferred without the need for any manual intervention, and can make your standby generator system or Uninterruptible Power Supply (UPS) system more resilient and easy to use.

Looking for a generator for your site? Contact us via the contact form below or give us a call to get started with your critical power solution
Our team will discuss your requirements with you, explaining the options available to you.
One of our highly skilled generator engineers will visit your site to map out to take note of your power requirements, where the generator will be installed, answering any questions you may have
Once the order has been placed, our team will then install your generator on site. We also carry out rigorous commissioning processes to ensure that your equipment is ready to support your site.
In the world of generators and power supply, an automatic transfer switch is a device that controls the power supply. ATS equipment can be described as ‘self-acting’, as it detects the flow of power without the need for any intervention or input from a user.
The transfer switch automatically moves the power supply from the primary source (i.e. the grid mains supply of electricity) to the backup supply (i.e. your backup generator). You can also use an automatic transfer switch to move the supply between multiple generators.
The automatic transfer switch contains technology that monitors and tracks the power supply. It has a set limit, and kicks in when the voltage drops too low. Similarly, when the voltage returns to normal limits, the switch will transfer the supply back from your backup system to the mains grid, automatically.
Automatic transfer switches are equipped with a countdown timer, that begins working when the change in voltage is first detected. This means that there won’t be any unnecessary switching for just a temporary or significantly minor outage. As a result, you won’t find your generator draining or being used unnecessarily.
Once you’ve got the switch set up and configured with your mains supply and generator, it’s up and running. This is particularly useful for larger businesses or locations where the generator supply and equipment isn’t within easy reach.
With an automatic transfer switch, you don’t need to worry about total downtime at your business. Without a self-acting switch, you’d need to manually start up your diesel generator in the event of a power cut or outage, and wait for it to start up. This way, the switch automatically detects when the voltage goes outside its normal range, and starts up your backup power system.
In a business setting, having a switch to detect power ranges and voltage of the supply can offer a level of safety. The automatic transfer switch means you or a member of your team won’t have to manually intervene in the event of a problem with the power supply.
"Your engineer was absolutely brilliant - he got the generator working again really quickly and so I have power; he was also really professional and a real asset to your company. I would recommend your company in a heartbeat. Thank you all for helping me out in a time of need. I'm very grateful."
"I would like to say that your company is very customer driven. To offer a service outside your normal scope to fulfil a market need is exceptional and professional. When our new generator requires a service, I will contact Vital Power again"
"I wanted to say a big thank you for the way my generator was installed by one of your engineers. It was done extremely professional and quickly. The engineer projected a tremendous sense of enthusiasm and confidence – and his small-talk is also most interesting to hear. I was left in awe of his complete understanding of the installation requirements. He even management to iron out a difference on the auto start that the manufacturer did not tell him about. A very clean and good working in all respects, he is a tribute to your company"
"Everyone at Vital Power is very professional. I was really impressed with Managing Director, he worked very hard to make sure we were happy and got everything right. The engineers were superb and extremely professional when they came to inspect our cabling requirements. We couldn't be happier with the result and I couldn't fault the work at all. We're really pleased."
"Very happy with the engineer that was on site yesterday to get involved with the power switchover. All went successfully and brilliant result! Thank you."
"Credit to Warren, he's been absolutely unbelievable. To get the generator working in the time that he has is amazing. Great work and thanks again."
"I have just received a phone call from the client in regards to the engineer’s visit yesterday. They were very impressed by him, so much so they are thinking of switching all other generators they have over to you. It’s so good to get positive feedback, thanks again for your help"
"Your engineers are great, they are keen to help and work proactively to get things done. We were also seriously impressed with Phill Walters getting an emergency hire set to us in just 2-hours from the initial phone call!"
