The Vertiv Liebert STS2-PDU Static Transfer Switch-Power Distribution Unit provides power distribution and automatic switching between two different AC power sources such as different UPS systems.
The STS2-PDU 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 Liebert STS2-PDU is available in 250A, 400A, 600A and 800A systems, in both 60Hz and 50Hz. 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.
