ATS controllers – Reliable, flexible & efficient power transfer solutions




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.

Key features of modern ATS controllers

Supports Any Power Source

Advanced ATS units can operate in both traditional Generator–Mains mode and Source–Source mode. This means they can handle virtually any setup-including dual mains inputs, genset‑hybrid combinations, and renewable energy sources.

Seamless Blackout Prevention

With features like overlap switching, modern ATS controllers prevent blackouts by keeping both breakers closed for a user‑defined period, allowing short‑time paralleling for a smooth transition between sources.

Flexible 2‑ or 3‑Breaker Operation

Whether your system uses two or three breakers, a quality ATS controller can be configured to handle complex setups-such as opening and closing bus tie breakers between two power sources-making it suitable for global applications across many industries.

Easy Installation & Intuitive Operation

IP65‑certified, front‑mounted designs and sunlight‑readable LCD displays make the newest ATS controllers simple to install and operate. With configurable parameters and support for utility software like M‑Logic, setup becomes fast and user‑friendly.

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.
