ATS controllers (Automatic Transfer Switch controllers) are essential components in emergency power systems, ensuring seamless and reliable transfer between primary and backup power sources. Modern ATS controllers-such as the advanced AGC‑150 ATS-are designed to enhance uptime, protect critical equipment, and maintain stable power in facilities of all sizes.

What is an ATS controller?

An ATS controller monitors the primary power source for voltage, frequency, and other irregularities. If an outage or anomaly occurs, the controller automatically switches to a secondary power source-such as a genset, renewable system, or battery energy storage-ensuring uninterrupted operation.

Why choose a modern ATS Controller?

• Minimize downtime during grid failures

• Optimize power flow across multiple sources

• Enhance safety and equipment protection

• Support hybrid and renewable power systems

• Ensure automatic, hands‑off system operation

Whether you are managing a data center, commercial building, industrial facility, or renewable‑hybrid power plant, the right ATS controller ensures your power system performs safely and efficiently under all conditions.
