High-Reliability Static Transfer Switch (STS) Systems
DNS Power Systems manufactures industrial-grade Static Transfer Switches (STS) designed to deliver seamless, ultra-fast power transfer between two independent AC power sources. Utilizing high-speed solid-state SCR technology, our STS units automatically switch to a backup source within less than a quarter of a cycle (less than 4-5ms) in the event of a voltage drop, failure, or fluctuation in the primary source.
Engineered for maximum resilience and continuous uptime, these systems eliminate single points of failure in power distribution. They provide ultimate power security for data centers, telecommunications, petrochemical processes, and automated production lines where even a millisecond of power interruption is unacceptable.
