Automatic Transfer Switching (ATS) Buyers Guide: Reliable Options from China in 2025


When it comes to ensuring uninterrupted power supply, Automatic Transfer Switching (ATS) is a critical component for businesses and industries. Whether you're looking for backup power solutions or need to switch between primary and secondary power sources seamlessly, ATS systems play a vital role. This guide will help you understand the different types, features, and how to find reliable suppliers from China in 2025.


How to Find Reliable Automatic Transfer Switching (ATS) from China in 2025


Sourcing Automatic Transfer Switching (ATS) from China requires careful consideration of suppliers' reliability, certifications, and product quality. Look for manufacturers with ISO 9001 certification and a proven track record in the industry. Platforms like Alibaba can help you compare multiple suppliers, but always request samples and check customer reviews before making a decision.


What Buyers Should Know Before Buying Automatic Transfer Switching (ATS) from China


Before purchasing an ATS, consider the voltage requirements, load capacity, and switching time. Chinese manufacturers often offer competitive pricing, but ensure the product meets international standards like IEC 60947-6-1. Additionally, verify the warranty and after-sales support to avoid future complications.


Types of Automatic Transfer Switching (ATS)


There are three main types of ATS:

  • Open Transition ATS: Breaks connection with the primary source before connecting to the backup, causing a brief power interruption.
  • Closed Transition ATS: Ensures no interruption by briefly paralleling both power sources during the switch.
  • Static ATS: Uses solid-state components for faster switching, ideal for critical applications like data centers.


Functions and Features of Automatic Transfer Switching (ATS)


Modern ATS systems come with advanced features like remote monitoring, self-testing, and programmable logic controllers (PLCs). These features enhance reliability and reduce downtime. For example, some models can automatically detect power failures and switch to backup within milliseconds.


Scenarios of Automatic Transfer Switching (ATS)


ATS is widely used in:

  • Hospitals: To ensure life-saving equipment remains operational during power outages.
  • Data Centers: To prevent data loss and maintain server uptime.
  • Manufacturing Plants: To avoid production delays caused by power interruptions.


How to Choose Automatic Transfer Switching (ATS)


When selecting an ATS, consider:

  • Load Capacity: Ensure the ATS can handle your maximum power load.
  • Switching Time: Critical applications require faster switching times (under 100ms).
  • Compatibility: Verify compatibility with your existing power sources and generators.
