Redundant Power Supply Motherboard Assembly

摘要

A redundant power supply motherboard assembly connects control segments of a fieldbus-type control system to a host computer. The assembly has a compact design with pairs of power supply modules in side-by-side nests on the motherboard. The nests are mounted on the motherboard in desired locations and securely hold the modules on the assembly despite vibrations, shocks and handling to prevent contact impairment. The nests provide touch protection for components on the motherboard.
