The Smart Automatic Transfer Switch monitors voltage fluctuations and grid outages in real time. The moment standard grid power drops below safe operating limits, the unit immediately disconnects the municipal utility lines and shifts connected household circuits to your backup inverter or generator without resetting computers, televisions, or boiler automation systems.
Built with dual mechanical and electronic interlocks, this transfer switch completely prevents dangerous backfeeding into the utility grid. An integrated micro-controller continuously evaluates line frequency and phase stability, returning your home to utility power only when the municipal supply has remained stable for three consecutive minutes.
Deploying an automated transfer switch eliminates manual selector handling during blackout emergencies. Certified electricians integrate the unit directly into your primary distribution panel following standard DIN-rail conventions.
Connect primary utility line feed to Input A and secondary backup power lines from inverter or generator to Input B.
Wire auxiliary signaling contacts to generator automatic electric start control boards or hybrid inverter dry contacts.
Configure delay timers on the front panel display to prevent false switching during brief micro-surges or voltage dips.
Once installed, the system functions completely autonomously. Front-mounted status LEDs visually indicate active source selection, grid phase readiness, and load current drawing levels at all times.
