Seamless input source transfers for sensitive critical loads. The Zenith STS-3 Series uses solid state SCR (Silicon Controlled Rectifier) technology to supply critical loads with a choice between two available sources of electrical power. By continually monitoring power quality, the STS-3 Series switch automatically transfers to an alternate source without interruption of power to even your most sensitive critical loads. With a sense and transfer time of less than 4ms and the industry’s best communication package, the GE STS-3 Series represents the highest performance power switching solution available.
