Functions

Automatic power transfer – when the main voltage fails, the load is transferred to the backup source
Automatic return to the main grid – when stable voltage is restored, the power supply is switched back
Overvoltage protection – protects equipment from excessively high mains voltage
Undervoltage protection – protects against dangerous voltage drops
Adjustable protection limits – desired operating voltages can be set
Adjustable power-on delay – waiting time before load activation can be configured
Fast switching – response time less than 30 ms
LCD display – shows voltage, operating mode, and settings
Manual / automatic mode – can be controlled automatically or manually
Three-phase network control – suitable for 3-phase electrical systems

Applications

In households and country houses: Suitable for users who have a generator during power outages, a solar inverter with backup line, water pumps, heating boilers, freezers, security systems.
For electricians and installation specialists: Suitable when automatic backup power, protection from grid surges, easy installation in the panel, and fewer additional relays and control components are required.
For engineers, designers, technicians: The device is suitable for designing automation panels, ATS backup circuits, industrial UPS nodes, generator systems, and backup power for server rooms.
In industry and commercial facilities: An excellent choice for production lines, cold storage rooms, servers, video surveillance, alarm systems, gate automation, ventilation equipment.

Can this ATS automatically switch power to a generator?

Yes, when the main grid voltage fails, the device automatically transfers the load to the generator or another backup source line as soon as proper voltage appears there.

Can the voltage operating limits be adjusted?

Yes, the user can set both the overvoltage and undervoltage limits according to the needs of the electrical system.

Where is this device most commonly used?

It is widely used in homes, workshops, server rooms, pump systems, security equipment, production lines, and other facilities where uninterrupted power supply is important.

Is this model suitable for a three-phase system?

Yes, this is a 3-pole ATS model designed for automatic backup switching of three-phase electrical circuits.
