Static Transfer Switch

The Static Transfer Switch (STS) safeguards the uninterrupted operation of mission-critical IT equipment. Powered by two independent power sources, the STS rapidly switches from one source to the other automatically when the power supply used to power its connected load fails. For datacenter applications the STS allows power drop risk to be shared or distributed to each rack to prevent power loss for the whole system. The STS offers an efficient and reliable switch that supports the high redundancy requirements of mission critical power systems.
