The KONGSBERG PSU-MAIN 382-079671 is a marine-grade high-performance main power supply unit. It is designed for ship automation, dynamic positioning (DP) and offshore platform control systems. Its core function is to deliver stable and redundant multi-voltage DC output for critical systems including K-Chief and K-Pos, serving as a key component of the vessel's power safety architecture.382-079671 is the official part number, and its matching model is AE10082-G. It is compatible with the full range of Kongsberg marine automation platforms.
Core Advantages
Integrated Multi-voltage OutputA single module provides stable multi-channel outputs of 6V, 12V and 24V DC, covering power supply for control, communication and sensors, and simplifying system structure.
Wide Input for Grid FluctuationIt accepts AC input from 100V to 240V (50/60Hz), tolerating voltage fluctuation of ship main switchboards and preventing unexpected shutdowns.
Comprehensive Protection FunctionsBuilt-in over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OLP), short-circuit protection (SCP) and surge protection. It cuts off power automatically and triggers alarms upon faults to protect downstream equipment.
Redundancy & Hot-swap DesignSupports 1+1 redundant parallel connection with seamless switchover when one unit fails. Hot-swap capability allows online replacement without system interruption, meeting redundancy requirements for DP2/DP3 vessels.
Intelligent Status MonitoringEquipped with LED indicators for normal operation, faults and alarms. It outputs fault signals via relay dry contacts and supports remote monitoring through K-Chief system.

FAQ
Q1: LED indicator stays off and no output after power-onTroubleshooting: ① Check input power (voltage, wiring and fuse); ② Ensure reliable PE grounding; ③ Verify if the internal input fuse is blown; ④ Inspect the rear load for short circuits.Solutions: Replace the blown fuse with one of the same specification; repair short-circuited loads. If input power is normal but there is still no output, the module is defective. Replace it via hot swap.
Q2: Unstable and fluctuating output voltageCauses: Fluctuating input power, aging filter capacitors, overload or loose wiring.Solutions: Check input voltage and install a voltage stabilizer if needed; replace degraded capacitors; keep the load within 80% of rated power; retighten terminal connections.
Q3: Red LED flashes with frequent alarmsCauses: Overcurrent/short circuit, overtemperature, input overvoltage/undervoltage or abnormal redundancy switchover.Solutions: Disconnect the load to locate short circuits; remove dust and improve ventilation; adjust input voltage to the normal range; check the status of the standby module under redundant configuration.
Q4: Failed switchover after redundant parallel connection, resulting in system power loss upon single-module failureCauses: Inconsistent model or firmware versions, incorrect wiring, disabled redundancy function or defective standby module.Solutions: Ensure all parallel modules share identical model and firmware versions; recheck redundant wiring in accordance with the manual; enable redundancy mode; test and replace the faulty standby module.
Q5: Module overheats and triggers alarm when temperature exceeds 70℃Causes: Poor heat dissipation due to dust accumulation or blockage, excessive ambient temperature, long-term full-load operation or faulty fan (if equipped).Solutions: Clean heat dissipation passages; enhance cabinet ventilation by installing cooling fans; limit the load to 80% of rated capacity; replace defective fans.
Q6: Can non-Kongsberg modules be used as a replacement?Answer: Direct replacement is not recommended. This is a custom marine-grade unit. Its output timing, alarm logic and redundancy protocols are deeply adapted to Kongsberg systems. Third-party modules may cause compatibility issues, system instability or invalidation of relevant certifications.
