Automatic transfer switches are a reliable resource for sending meaningful load connections.

There is a transfer of power between the primary power source and the backup power source. Data centers, businesses, and other facilities that need to operate continuously employ alternative energy sources. They utilize it for generators or backup utilities when the primary source is unavailable.

Automatic Transfer Switch Market Overview

With the help of an automatic transfer switch, the electrical load can be switched between two power sources automatically. When a utility line goes down, it is utilized in industrial, commercial, and residential buildings to transition from utility lines to backup power generators.

Market growth for automatic transfer switches is anticipated to increase by USD 248.77 mn between 2021 and 2026. Additionally, according to Technavio, the market’s growth momentum will pick up at a CAGR of 6.75% throughout the projection period.

Frequently Asked Questions About ATS

ATS Typical Transfer Sequence

1. Regular utility power sources are ineffective.

2. When the electricity from the generator or backup utility feed is stable, and within the permitted voltage and frequency limitations, the transfer switch switches the load to the emergency power source. The transfer procedure can be self-acting or manually triggered, depending on the requirements and preferences of a facility.

3. When utility power is restored, the transfer switch switches the load from the emergency power source to the regular power source. Either manually or automatically initiating the transfer process.

Businesses That Benefit the Most from Automatic Transfer Switch

Any business, no matter how big or little, can benefit from an automatic transfer switch. And we guarantee that you’ll think the cost was well spent. But when you consider an automatic transfer switch, certain businesses spring to mind, such as:

– Hospitals
– Government buildings
– Commercial structures
– Factories
– Warehouses
– Restaurants
– Schools

Things to Consider in Choosing the Right ATS Manufacturer for you business

The automatic Transfer Switch is permanently installed in your building and connected to your backup generator and your most crucial circuits. The switch can start the generator and automatically switch the loads from the utility grid to the generator if it detects a disturbance in the utility electricity.

Critical equipment disruptions are minimized as a result of this almost instantaneous action. There are various things to think about when choosing an automatic transfer switch for your facility:

Total Amperage

Amperage is a way to measure electrical current. A breaker will trip if you exceed the number of amps that each circuit in your building is designed to withstand to keep the wire from overheating and catching fire. The total amperage of all the courses that transfer switches will be switching is indicated by their current rating, which is another feature.

Once you’ve determined which circuits you’ll need to maintain electricity during a power loss, sum up all the devices on those circuits’ current demands, then pick a transfer switch that offers a sufficient margin for future development without exceeding that rating.

Voltage

Commercial and industrial buildings’ circuits can run at various voltages, such as 208/240 volts, 480 volts, and 575/600 volts. Make that your transfer switch supports the voltages of your equipment and circuits. All of the automatic transfer switches we provide at PSI Power & Controls have multi-tap transformers that can help 208/240, 480, and 575/600 volts.

Wattage

Watts are a gauge of strength. The watts of an electrical circuit are calculated by multiplying the circuit voltage by the device’s amperage. Many generators are rated in watts or kilowatts, so it’s critical to understand the total amperage and wattage of the loads you’ll be powering if you want to match the generator output to the transfer switch’s current restrictions.

Conclusion

This article provides a brief overview of each manufacturer and their automatic transfer switch, highlighting their strengths and unique selling points. Overall, the article serves as a useful guide for those seeking to identify top ATS manufacturers in the world.
