Product Description

Product Description

SJKQ2Z Dual Power Automatic Transfer Switch (ATS)

The SJKQ2Z Series Dual Power Automatic Transfer Switch (ATS) is a high-performance electrical switching device designed to ensure uninterrupted power supply by automatically transferring loads between two independent power sources (e.g., mains and generator). With a frame current range of 100-1250A and rated operational current of 10-1250A, this ATS is ideal for critical applications in industrial plants, data centers, hospitals, and commercial buildings.

Key Features:

     - Wide Current Range: Supports 100-1250A frame current and 10-1250A operational current for flexible deployment.
     - High Voltage Rating: Rated for 400V AC systems with 50/60Hz frequency compatibility.
     - Pole Configurations: Available in 3P (3-phase) and 4P (3-phase + neutral) versions.

     - Control Voltage: Operates with AC230V control power for reliable switching.

Working Principle:

The SJKQ2Z ATS continuously monitors both power sources (Primary and Backup). When the primary source fails or exceeds voltage tolerances (±15%), the built-in controller:

     - Detects the fault via voltage sensors.
     - Disconnects the primary source within milliseconds.
     - Transfers the load to the backup source after a programmable delay (0-30s).
     - Auto-reverts to the primary source once stabilized.
