In today's world, uninterrupted power is critical—whether it’s for homes, offices, factories, or retail stores. That’s where an Automatic Generator Changeover Switch (AGCOS) becomes essential. This smart device ensures a seamless switch between main power (grid) and generator during power failures, without any manual effort.
What is an Automatic Generator Changeover Switch?
An AGCOS is an intelligent panel or switchgear system that automatically detects power failure from the main electricity supply and instantly starts the generator. Once power is restored, it automatically switches back to the main supply and turns off the generator—saving fuel and wear.
How Does It Work?
Power monitoring: Constantly checks the availability and voltage level of the main power.
Automatic switching: On detecting a failure, it triggers the generator and switches load to it.
Reversion: When grid power is back, it switches load back and shuts down the generator.
Benefits of Using an Automatic Changeover Switch
✅ No manual intervention needed
✅ Faster switch = minimal disruption
✅ Protects sensitive electronics
✅ Saves fuel through timed shutdowns
✅ Ideal for remote, unmanned, or 24/7 operations
