An Automatic Transfer Switch with Display is a smart, microprocessor-controlled device that ensures uninterrupted power by automatically switching between utility and backup sources. The integrated display offers clear status updates, programming flexibility, and often remote connectivity—making it ideal for critical installations requiring precision, visibility, and reliable power management.
Description
An ATS with display is an advanced transfer switch that automatically manages power continuity between mains and backup sources. The integrated display provides real-time status, measurements, and configuration options via LEDs, numeric screens, or full graphic interfaces.
