Liebert is making it easier to protect your critical equipment by giving your single cord loads the reliability of dual cord power or by providing added redundancy to your dual cord devices. With a single, space-saving unit, the Liebert STS2/PDU static transfer switch/power distribution unit provides power distribution and automatic switching between two different AC power sources.
The packaged system approach of the Liebert STS2/PDU is convenient and space-saving, reducing installation time and cost compared to a conventional approach using multiple interconnected components. The STS2/PDU is built on proven system designs used in thousands of installations.
The Liebert STS2/PDU is available in 250A, 400A, 600A and 800A systems, in both 60Hz and 50Hz frequencies. Multiple input voltages are available. Designed for use in dual-bus power applications, this solution combines fast switching between AC power sources, power isolation, distribution, monitoring and grounding into a single package.
