Product Overview
The Kongsberg 382-219052 is a marine-grade charger printed circuit board designed for Kongsberg vessel automation and power backup systems. It manages battery charging functions, voltage regulation, charge state monitoring, and battery fault detection for onboard DC backup battery packs. Built to withstand marine shock, vibration, humidity and wide temperature fluctuations, this plug-in PCB is a critical spare part for shipboard power management cabinets. Original production has been phased out, so the 382-219052 board is commonly stocked as replacement hardware to maintain vessel safety and uninterrupted backup power during offshore, coastal and inland marine operations.

Installation & Maintenance Notes
- Isolate both the main 24V DC supply and battery terminals before removing or installing the 382-219052 charger board. De-energize the complete battery circuit to prevent short-circuit hazards.
- Verify battery type and rated voltage match board configuration after replacement; incorrect battery settings can cause overcharging, battery degradation or premature board failure.
- Check all terminal connections for corrosion and tightness. Marine environments accelerate terminal oxidation, leading to unstable charging current.
- After installation, perform a full charge cycle test and confirm charge status signals, alarm outputs and battery voltage readings match system documentation before sea trial.
- Spare boards must be stored in dry, temperature-controlled anti-static packaging. Inspect PCB for salt spray corrosion when received. No field component-level repair is supported.
Common Troubleshooting Tips
‑ Batteries fail to charge: Confirm 24V DC auxiliary supply to the charger board; inspect fuse and input wiring for corrosion or open circuit. ‑ Overcharge alarm continuously active: Check battery health, battery internal short, and board voltage sensing circuit. ‑ Intermittent charging / unstable charge current: Inspect connector pins for salt contamination, loose rack seating, and poor battery terminal contacts. ‑ No status output signals: Verify board power feed and backplane connector integrity before replacing the charger PCB.
