STS-100 static transfer switch(STS)

The STS dual-input AC converter switch is a paragon of intelligent power management. Integrated with advanced control systems, it continuously monitors the status of both AC inputs, collecting data on parameters like voltage, current, and frequency. Using this real - time information, the STS can proactively predict potential power issues and initiate preventive switching actions. For example, if it detects a gradual degradation in the quality of the primary power source, it can switch to the secondary source before a failure occurs. This intelligent management not only ensures uninterrupted power supply but also provides valuable insights for power system optimization and maintenance, making it a high - tech solution for modern power distribution networks


Key features:

  • . Switch over between two power suppliers
  • .Automatic Selection of batter supply
  • . Switch over time less than 4ms
  • .Any two AC power supplies with sinusoidal output high adaptability
  • .Provide RS485 communication and Dry contact
