About The ACO100 Deluxe Auto Change-Over Switch
The ACO100D is an advanced electronic automatic changeover switch designed to replace traditional manual changeover switches with an intelligent and long-lasting solution. It automates your power backup operation using electronic sensing and adaptive logic, guaranteeing consistent automatic operation without human intervention.
The ACO100D is ideal for:
Residential users
Estates & property managers
Small Office
Wherever power may not be interrupted, the ACO100D is a reliable ally.
Key Features & Benefits
Defaults To The Generator at Power Failure
At power failure, the user only has to start the generator. The ACO100D automatically picks up the power and connect the load.
Automatically picks Up The Mains at Power Restoration
Automatically picks up the mains at power restoration. If the generator was running, the ACO100D would connect the load to the mains and shut down the generator.
Real-Time Notifications
The ACO100D sounds a 10-second siren at power restoration.
Adaptive Pump Control Logic
Reduces unnecessary pump cycling, saves energy, and extends pump lifespan.
Undervoltage, Overvoltage & Surge Protection
Built to withstand irregular voltage and harsh electrical environments common in Nigeria and other developing regions.
