Advances in Large Corporation computing, storage technologies, an increasing power demand, requires a change in Large Corporation power protection technology. Symmetra PX 40000VA, three phase input/ three phase output (3:3), is a single unit, composed of modular components. This modular architecture provides the foundation of building and scaling near-continuous availability power systems with a flexible range of power capacity. The Symmetra PX 40000VA packages the high availability requirements of easy power and runtime scalability into a very small footprint. Combined with the complete line of APC datacenter protection software and accessories it provides the four most critical elements of total datacenter protection.Advances in Large Corporation computing, storage technologies, an increasing power demand, requires a change in Large Corporation power protection technology.
