SymmetraTM Overview

The SymmetraTM is a high-performance, uninterruptible power “array” system, designed for large-scale loads. It pro- vides conditioned, reliable AC power to load equipment, and provides protection from power blackouts, brownouts, swells, sags, surges and interference. The SymmetraTM Power Array system is comprised of either a MiniFrame, or a MasterFrame, and a variable set of modules. A MiniFrame system can be configured to deliver a maximum output of 8kVA, and a MasterFrame system, a maximum of 16kVA.

Theory of Operation

The SymmetraTM Power Array is comprised of three func- tional components: A power processing system, a battery source, and a control/user interface system. Output power is routed through a transformer prior to delivery to the load equipment. See figure I-2. Each of the functional components and the transformer are described in the following text.
