The document summarizes the specifications and features of the ComNet C1PS modular power supply. Some key points: - It uses automatic electronic current limiting within each rack-mountable module rather than the power supply, preventing shutdown of all modules if one fails. - Modules are hot-swappable without needing to power down the rack. - It provides unconditional protection from power surges and other voltage transients. - Specifications include an input voltage of 90-264VAC, output of 9VDC at 6.5A, and dimensions of 5.25 x 1.95 x 7.75 inches.
