What Is an ATS?
Basic Function
An Automatic Transfer Switch (ATS) helps keep your power on. It works when your main power stops working. You do not need to do anything. The ATS checks the voltage and frequency of your main power. If it finds a problem, it switches to backup power, like a generator. This switch happens very fast. Your lights and computers stay on without stopping.
Note: The ATS uses a smart controller to watch your power all the time. It can tell if the voltage is low or if the power goes out. When this happens, the ATS connects your backup power right away. When your main power comes back, the ATS switches you back. This keeps important equipment safe in places like hospitals, data centers, and homes.
You can find ATS devices in many places. In homes, they keep your fridge and lights working during storms. In businesses, they stop computers and machines from turning off. The ATS makes sure you have power, even if the main source fails.
Why Price Varies
You may wonder why some ATS units cost more than others. The price depends on a few important things:
- Power Capacity: Home ATS units handle less power. Commercial ATS units manage much bigger loads for large buildings or factories.
- Features: Some ATS models only switch power. Others have extra features like load management, surge protection, and remote monitoring.
- Installation Complexity: Installing a home ATS is usually easy. Commercial ATS units need experts and must follow strict rules.
- Design and Durability: Commercial ATS units use stronger parts. They last longer and work in tough places.
Here is a table to show the main differences:
