Configurable power supply chassis products are the outermost component of a user-configurable power supply system. Such systems are modular in nature, allowing rapid construction of semi-custom power conversion products by the insertion of output-specific conversion modules into an outer chassis that provides mechanical containment and typically a number of electrical factors that are common/shared among the conversion modules, such as rectification and power factor correction. Product series represented in this family are user-configurable and do not require specialized tools or training for assembly.
