3-Pole Automatic Transfer Switch (ATS) – For 3-Phase Critical Power Systems

Core Technologies & Operational Advantages:

1. Comprehensive 3-Phase Power Quality Monitoring:

   • Technology: The integrated digital controller simultaneously analyzes voltage and frequency on all three phases (L1, L2, L3) of the primary source. It can detect faults including complete outage, severe under/over-voltage, phase loss, and frequency drift.

   • Benefit: Ensures only clean, stable, and complete three-phase power is supplied to your equipment. Prevents transfer on transient faults and protects sensitive three-phase motors from the damage caused by phase imbalance or loss.

2. Fast, Sequential Transfer Logic:

   • Technology: Upon a qualified fault, the controller sends a start signal to the backup generator. After a user-adjustable time delay (to allow the generator to reach stable voltage and frequency), it commands the robust switching mechanism to transfer all three phases simultaneously.

   • Benefit: Minimizes the “break” time to typically less than 100 milliseconds for closed transition options (or a few seconds for open transition), ensuring most industrial processes and motor loads continue to operate without disruption or damaging inrush currents upon re-energization.

3. High-Performance Switching Mechanism:

   • Technology: Available with either a heavy-duty, electrically operated contactor or a power circuit breaker with a motorized operator as the main switching element. Both are designed for high making/breaking capacity and long electrical life.

   • Benefit: Guarantees reliable performance under full load and fault conditions. Provides positive mechanical and electrical isolation between the two power sources, a fundamental safety requirement to prevent paralleling.

4. Advanced, Programmable Microprocessor Controller:

   • Technology: Features a programmable logic controller with a clear display. Key settings include: Engine Start Delay, Transfer to Emergency Delay, Retransfer to Normal Delay, and Voltage/Frequency Setpoints.

   • Benefit: Allows fine-tuning to match specific generator characteristics and load requirements. Protects the generator from short cycling and ensures the utility power is truly stable before retransferring, enhancing overall system longevity.

5. Built for Industrial Reliability & Communication:

   • Technology: Housed in a robust enclosure (NEMA 1, 3R, or 12). Standard RS485 communication port with Modbus RTU protocol for integration into Building Management Systems (BMS) or SCADA.

   • Benefit: Enables remote monitoring of status, source voltages, and alarms. Facilitates predictive maintenance and integrates your power system into a centralized facility management platform.
