Static Transfer Switch | <2ms Switching, 99.999% Uptime

In the world of critical power protection, time is measured in milliseconds. ZHNYU Electric's static transfer switch (STS) leads the industry with an unmatched transfer time of under 2 milliseconds. This ultra-fast switching capability ensures that loads connected to sensitive electronic equipment experience no voltage dips or transients during source transitions. For example, in a financial trading floor, any interruption can cause significant losses; our STS minimizes that risk to virtually zero. Data from our global installations shows a 99.9% reduction in power-related incidents. This speed is achieved through advanced thyristor control algorithms that continuously monitor both power sources and initiate transfer within microseconds of detecting an anomaly.

ZHNYU Electric's static transfer switches are manufactured in a facility that spans over 10,000 square meters and is equipped with more than 100 advanced production machines. This significant investment in manufacturing capability ensures that every STS unit is fabricated with precision and consistency. Our quality management system is ISO9001:2015 certified, and our products meet the requirements of CCC, CE, and RoHS directives. Each STS undergoes comprehensive testing, including full-load burn-in tests, thermal cycling, and electrical endurance tests, to ensure it can operate reliably for more than 15 years. In addition, we use only high-grade materials, such as UL94V-0 flame-retardant plastics and silver-alloy contacts, to enhance safety and longevity.
