APC Symmetra PX is a high-performance redundant scalable power protection system that allows you to cost-effectively guarantee very high availability of protected systems. Symmetra PX is a fully modular system, ready for seamless integration into state-of-the-art data centers. It consists of dedicated and redundant modules - power, control, battery and bypass modules. All of them feature easy serviceability, and are designed to scale power and runtime according to changing requirements. The Symmetra PX acts as the central power system for APC InfraStruXure systems in small and medium-sized data centers, but it works equally well as a "zone" power system in larger centers. Among the features of the Symmetra PX system that facilitate management, self-diagnostic functions and module standardization that reduce the risk of human error are particularly noteworthy.
