Raritan's innovative rack transfer switch designed for performance and reliability.Raritan's hybrid rack transfer switches use electromechanical relays and siliconcontrolled rectifiers (SCRs) to transfer a load between two sources. The result is performance and reliability that exceeds that of standard automatic transfer switches (ATS) and at a lower price point than static transfer switches (STS).Industry leading performance: Uses SCRs to provide STS-like transfer times and eliminate electrical arcing and welding of relays; hybrid relay plus SCR-design allows hand off of the transferred load to a relay, making it power efficient and producing less heat. Fast detection time ensures failed power feeds are detected and the loads transfered within 4 to 8ms. Only rack transfer switch with power metering, energy quality monitoring and support for optional environmental sensors. Local and remote web-based monitoring and control
