The ABB DPT‑CB011 is a dual‑power automatic transfer switch (ATS) controller used in electrical power distribution systems to automatically transfer load between two independent power sources (e.g., utility mains and a backup generator) when one source fails or returns to normal. It provides automatic change‑over and self‑recovery functionality with built-in control logic and safety features suitable for commercial and industrial applications. This controller can operate with compatible ATS switch assemblies and supports monitoring of voltage levels, phase presence, and alarms or delays during switching to ensure safe and reliable power continuity.
