The AIF-CASE-KIT is a metal casing assembly designed for use with AIF series high voltage DC-DC converters and power factor correction (PFC) modules. The kit includes a metal casing, shield, and insulator made from 94VTM-0 material, providing additional radiated EMI screening functionality. It is compatible with all AIF full-brick series modules and features UL-approved materials for safety compliance. The case kit fits modules with dimensions of 116.8 mm length (4.6 inches), 12.7 mm height (0.5 inches), and 60.96 mm width (2.4 inches), and is designed to be installed before soldering. This accessory is essential for applications requiring electromagnetic interference mitigation and mechanical protection in power conversion systems.
