Does Your Generator Need an Automatic Transfer Switch

What an ATS actually does

• It senses the grid supply, starts the generator when the grid fails, and switches the load over to the generator.
• When the grid returns, it switches back and shuts the generator down after a cool-down period.
• No one has to be on site to start the machine.

When it is worth the money

• Anywhere the generator sits idle at night: clinics, telecom sites, cold rooms, hotels.
• Sites where the staff cannot be relied on to start a set in the dark.
• Where response time matters more than the cost, such as a vaccine cold chain.

When you can skip it

• A construction site where someone is always present can use manual start.
• A house used only in the evening can use a manual or remote key start.

What to check before ordering

• The ATS must match the generator output in kW and in phase (single or three phase), and match your grid voltage and frequency.
• Ask for a short changeover time if sensitive equipment is connected.
• Our sets can be supplied ATS-ready with the correct control panel wiring.
