1. Overview

AC DC Configurable Power Supply Chassis refers to modular power systems that can be configured for AC-to-DC or DC-to-DC conversion, supporting both external and internal (off-board) mounting. These chassis provide critical power management solutions for complex electronic systems, enabling customization through interchangeable modules. Their importance in modern technology stems from the growing demand for adaptable, high-efficiency power systems in industrial automation, medical equipment, and data centers.
