The ATS box unit for Unicraft PG-I SE HC inverter generators is designed to automatically manage the changeover between the main power network and an emergency generator. It is compatible with Unicraft generators equipped with CONN interface, including petrol and diesel HC models, and provides a practical solution for users who need a safer and more organised way to operate a generator during mains power failure.

The ATS unit works by monitoring the mains voltage. When a voltage drop or power failure is detected, the device automatically manages the switch from the main network to emergency power and enables the connected generator to start automatically. This allows the generator to take over the power supply without requiring immediate manual intervention, improving service continuity in applications where essential loads must remain available.

When normal voltage is detected again, the ATS unit performs the reverse changeover, switches off the emergency generator and restores the connection to the main supply network. This process reduces manual operations, helps prevent incorrect switching procedures and makes generator management more efficient, especially in domestic, technical and professional environments where electrical continuity is an important operating requirement.

The unit is suitable for homes, small installations, workshops, craft activities, technical services, work areas, temporary installations and electrical backup applications. It can be used when a compatible generator is intended to supply emergency power to properly prepared circuits, always in compliance with electrical regulations and with installation carried out by qualified personnel. Correct use of the ATS helps integrate the generator into a more controlled system, reducing manual connections and improving backup power management.

The ATS box has a compact structure, with approximate dimensions of 320x250x140 mm and an approximate weight of 6 kg. These features make installation easier near the generator or the prepared electrical panel while keeping the overall footprint limited. Before purchase, it is important to check compatibility with the generator model and verify the presence of the CONN interface, which is required for correct connection of the unit.
