Static Transfer Switches
Automatic, break-free transfer between two independent power sources — true 2N power redundancy for critical loads.
Redundant power paths only protect you if the load can actually switch between them. A Static Transfer Switch (STS) transfers your critical load between two independent sources in milliseconds — far faster than any mechanical switch — so connected equipment never notices.
Where it fits
STS units are the backbone of 2N architectures: two UPS systems, two distribution paths, and automatic break-free selection between them. Rack-level units also protect single-corded equipment in dual-feed server rooms.
