Configurable power supply chassis serve as the outermost component of a modular power supply system that can be customized by users to meet their specific power conversion needs. These systems are designed to allow for easy and quick assembly of semi-custom power conversion products. Users can insert output-specific conversion modules into the chassis, which provides mechanical containment and typically several electrical factors that are common/shared among the conversion modules, such as rectification and power factor correction. These chassis products are part of a family of user-configurable power supplies that do not require specialized tools or training for assembly. They are designed to be highly flexible and adaptable, allowing users to easily configure and customize their power supply solutions based on their specific requirements. By offering a modular and customizable approach to power supply design, configurable power supply chassis provide a cost-effective and efficient solution for a wide range of applications. Users can easily swap out conversion modules as needed, making it easy to upgrade or modify their power supply systems over time.
