Full Product Description

The stand-alone Static Transfer Switch (STS) is a high-performance power solution for Tier 3 and 4 critical power infrastructures, such as Hyper Scalers and Colocation facilities. It provides uninterrupted power between independent sources, making it ideal for demanding environments.

Designed and engineered with safety in mind a fully bussed internal design eliminates dozens of interval cable connections, bolted connections to re-torque and single points of failure. The only bolted connections to inspect or IT scanned are customer connections and STS module connections.

This STS product family allows for fast installation and easy maintenance. Housed within a robust cabinet, it includes an interchangeable module designed to continue feed equipment downstream while in bypass mode as you replace the module with the patented cold plug design, ensuring reliable and seamless power transfers. is designed to simplify the lives of electrical contractors, Data Center Operators and maintenance technicians. Its modular, internally bussed design reduces installation complexity and ensures easy servicing.
