ATS panel
Key Info
| Purpose | : | Automatically switches electrical load between utility power (grid) and backup generator during a power failure. |
| Main Functions | : | Monitors voltage and frequency of the utility supply. Detects power outage automatically. Starts the generator when utility power fails. Transfers the load from utility to generator. Returns the load to utility when power is restored. |
| Main Components | : | MCCB / Circuit Breakers – Protection for utility and generator lines. Automatic Transfer Switch – Performs the power switching. ATS Controller – Intelligent unit that manages the operation. Contactors or Motorized Switch – Physical switching mechanism. Timers & Relays – Control delays for safe transfer. Control MCBs – Protect control circuits. |
| Working Principle | : | Utility power is normal → Load runs on grid. Utility fails → ATS detects loss. Generator starts automatically. ATS transfers load to generator. Utility power returns → ATS switches load back to grid and stop |
| Applications | : | Hospitals Data centers High-rise buildings Factories Airports Security and IT systems |
| Advantages | : | Automatic operation (no human intervention). Fast power transfer. Protects critical equipment. Ensures continuous power supply. |
