ATS Panel

An ATS panel (Automatic Transfer Switch panel) is an electrical control center that automatically switches a building's power from the main utility source to a backup generator or other standby source during an outage, and then switches it back when the main power returns, ensuring uninterrupted power without manual intervention — crucial for hospitals, data centers, and businesses.

How It Works

• Continuously monitors utility power for voltage and frequency
• Detects an outage when power drops below safe limits
• Signals the standby generator to start and warm up
• Transfers the electrical load once the generator is ready
• Restores power to the grid when stable, then shuts down the generator after a cooldown period

Key Components

• A transfer switch (the core switching mechanism, e.g. contactors)
• A microprocessor controller managing logic, timings and protections
• A metal enclosure housing the components
