Automatic Transfer Switches

Automatic transfer switches offer a direct and immediate switching between utility (main) and supplementary or standby power sources. These devices are ideal when used in combination with a tap box setup and a generator, and offer a business an easy and safe means of maintaining access to reliable power during an unexpected outage or planned mechanical maintenance and testing.

In the event of a loss in power, the switch will automatically detect power loss and immediately switch to auxiliary power seamlessly within milliseconds, eliminating stutters in power that can result in complications for many businesses and industries. When utility power is restored and stable, the automatic switch will reverse and return power to the main source.

Automatic transfer switches offered by PSI Power & Controls come in ranges from 200-5000 amps, and are ideal for hospitals, manufacturing, gas stations, fuel centers, hospitality, educational facilities, and more.

All products are UL1008 Labeled and come with Cam-Lok® color-coded cables for fast and simple connection and circuit identification. Available NEMA enclosures include the NEMA 1, NEMA 3R, and NEMA 4X, suitable for indoor, indoor and outdoor, or both with added corrosion resistance respectively. Products can be service entrance rated, or non-service entrance rated accordingly.

Product Usage

Automatic transfer switches are particularly valuable for businesses that cannot handle any interruption in power. Due to the less than a second recovery time, ATS products are ideal for handling the power needs of vital tools and equipment, including heating and cooling, safety equipment, supply storage, lights and security systems, and tools that undergo routine servicing and maintenance.

All products come with a range of available accessories including testing kits, additional Cam-Lok® cables, mounting hardware, and ideal supplementary and complementary products (such as tap boxes and safety switches).
