ATS for generator 


An Automatic Transfer Switch (ATS) serves as the "brain" between your utility power and diesel generator, ensuring seamless power during outages. When the main power fails, it automatically starts the generator and switches the load; once mains power is restored, it switches back and shuts down the generator—critical for uninterrupted operations in hospitals, factories, and homes. Here’s how to select the right ATS for your needs:


1. Match the ATS Amperage to Your Load


ATS ratings range from 20A to 500A, and the key is to match its capacity to your peak power demand. First, calculate the total power consumption of all devices the generator will supply. The ATS must handle this load comfortably—undersizing can cause overloads, while oversizing wastes money. For example, a generator powering heavy machinery may need a 200A+ ATS, while a small home backup might suffice with 30A.



2. Consider Your Power Type (Single-Phase vs. Three-Phase) ATS for generator 


Ensure the ATS matches your generator’s voltage type:


Single-phase ATS: For residential or small commercial  ATS generators (common in 220V setups).

Three-phase ATS: For industrial generators powering heavy equipment (typically 380V/400V). Mismatched phases can damage equipment.

3. Prioritize Reliability and ATS Brand


Output  for reputable brands like SOCOMEC or Schneider, which offer durable, safety-certified ATS systems. These brands provide features like mechanical interlocking (preventing simultaneous connection to mains and generator) and long service life—critical for minimizing downtime. we supply ATS for generator from 5KW-12KW. 20-50A.


4. ATS Specialized Needs for Sensitive Environments


For high-stakes settings (e.g., hospitals, telecom towers), choose bypass isolation ATS. This advanced system allows maintenance without shutting down power, ensuring continuous operation even during repairs.

By following these steps, you’ll ensure your ATS works harmoniously with your diesel generator, keeping power flowing when you need it most. Always consult a professional to assess your specific load and environment—investing in the right ATS today prevents costly disruptions tomorrow.
