The Kongsberg PSO-P (Power Switch Over Unit, Part No. 8100334) is a critical redundancy module designed for marine automation systems (e.g., K-Chief 500/600, AutoChief C20). It acts as a seamless switch between two independent 24V DC power sources, delivering reliable, redundant power supply to Distributed Process Units (DPUs). Equipped with two 24V DC inputs and five 24V DC outputs, it also integrates relay outputs for alerting Power #1 and Power #2 failures, alongside automatic fuses to enhance system safety. This module ensures uninterrupted power distribution, minimizing downtime and supporting the stable operation of vessel alarm monitoring, propulsion control, and power management systems.
