Description
The Kongsberg GLS-90 (often referred to as the GL-90) is a specialized, ruggedized Power Supply Unit (PSU) specifically designed for Kongsberg maritime automation and bridge systems. It is engineered to provide stable, regulated DC voltage to high-availability control racks, such as those found in DP (Dynamic Positioning) systems, K-Chief automation arrays, and navigation console electronics. Known for its reliability in harsh marine environments, the GLS-90 features built-in protection against voltage spikes, transients, and short circuits, ensuring that critical control processors remain operational despite fluctuations in shipboard power.

Important Implementation Note: The GLS-90 is often installed in a Redundant Configuration (e.g., dual PSUs feeding a shared bus via a diode/voting module). When replacing a faulty unit, ensure that the DC output voltage is measured and calibrated to match the secondary redundant PSU exactly before connecting them to the common load. A voltage mismatch between parallel-connected power supplies can lead to “Current Hogging,” where one unit carries the entire load and potentially overheats.
