Three-Phase ATS Automatic Transfer Switch Manager for Photovoltaic Panels and Backup Source

The three-phase ATS is an intelligent automatic power source switching device, designed to ensure continuous power supply by quickly switching between the main source and the backup source. It is ideal for industrial three-phase systems, commercial buildings, photovoltaic installations, and applications requiring uninterrupted power.

Key Features

• Two-position switch design (Source A and Source B): allows using a primary source and a backup source, e.g., a three-phase generator.
• Automatic and manual operation: fast and flexible switching between sources for maintenance or emergencies.
• Fast switching speed <50 ms: prevents shutdown of connected critical equipment.
• Current capacity: up to 63A, suitable for 50–60Hz three-phase systems.
• Under-voltage protection: stable operation at voltages between 85% and 110% of nominal.

Operating Modes

1. Automatic Mode:
   • Continuous monitoring of the main source voltage.
   • Automatic switch to the backup source in case of power outage.
   • Automatic return to the main source after voltage is restored.
2. Manual Mode:
   • Manual switching for maintenance operations.
   • It is recommended to fully shut off power before manual switching.

Recommended Applications

• Commercial buildings: continuous power for critical equipment (elevators, ventilation, IT systems).
• Three-phase photovoltaic installations: switching between solar energy and the public power grid.
• Factories and workshops: automatic switch to three-phase generators during outages.
• Data centers and servers: uninterrupted power for sensitive equipment.

Usage Examples

1. Main source: Public power grid | Backup source: Three-phase generator
   • Automatic switch to generator during a power outage and return to the grid when power is restored.
2. Main source: Three-phase photovoltaic system | Backup source: Public power grid
   • Fast switch to the public grid when the solar system does not supply enough power.

Benefits

• Increased safety: protects critical equipment through fast and reliable source switching.
• Operational flexibility: automatic and manual modes for various situations and maintenance.
• Energy efficiency: prioritizes the main source to reduce consumption.
• High durability: built for demanding industrial and commercial environments.
• Easy installation: mounts on a DIN rail in the electrical panel.

The three-phase ATS is the ideal solution for intelligent power management in commercial and industrial applications, ensuring continuity, safety, and energy efficiency.
