Description
Kongsberg 382-219052 Battery Charger Board
Product Overview
The Kongsberg 382-219052 is a battery charger board used in Kongsberg’s TTC 400 acoustic transponder architecture. Kongsberg’s official TTC 400 instruction manual identifies 382-219052 specifically as the Battery charger board and lists it among the unit’s main line-replaceable modules. The same spare-parts section identifies the 382-219490 TX(MF) transmitter board, 382-083602 RX receiver board, 382-219335 microcontroller board, 382-098602 power supply, 382-219337 motherboard, and 290-220142 battery pack as other major TTC 400 assemblies.
The Kongsberg Simrad 382-219052 is therefore not a general-purpose marine PLC power module. Its function is tied to the battery-backed power architecture of the acoustic equipment. In the ACC 401 MF documentation, 382-219052 is also listed as the battery charger board, alongside the 48 VDC/1 A/45 W 382-098602 AC power supply and the associated battery pack. This distinction is important: the 48 VDC/1 A/45 W specification belongs to 382-098602, not to the 382-219052 charger board.
For replacement work, the Kongsberg 382-219052 should be matched by complete part number, board revision, connector arrangement, and host equipment. Current component records also show versions marked 382-219052C / 381-219051B, so revision and board markings should be documented before ordering.

Specification note: Kongsberg’s official manual confirms the board’s identity and system position, but does not provide a standalone electrical specification table for 382-219052. Some current secondary listings claim a 24 VDC marine auxiliary input and detailed charging characteristics, but those figures are not sufficiently supported by the Kongsberg documentation reviewed here. They should not be treated as definitive specifications for procurement.

Main Features and Engineering Considerations
The main engineering value of the Kongsberg 382-219052 is its position within the equipment’s battery-backed power system. It is a dedicated charger board rather than a generic DC power supply. In the TTC 400, the board works as one part of a larger architecture that includes the dedicated power supply, battery pack, motherboard, processor, receiver, and transmitter assemblies. Replacing the charger board without checking the surrounding power system can therefore leave the underlying fault unresolved.
The official TTC 400 parts list is particularly useful because it establishes the relationship between the charger board and the other LRUs. 382-098602 is the power supply, 290-220142 is the battery pack, and 382-219052 is the charger board. These part numbers should not be conflated when diagnosing a charging problem.
The ACC 401 documentation provides the same architectural distinction. It lists 382-219052 as the battery charger board while separately specifying 382-098602 as the AC power supply rated at 48 VDC/1 A, 45 W. This is a useful procurement check because some secondary descriptions incorrectly transfer power-supply specifications to other boards in the assembly.
Board revision is another practical concern. Current component records identify units marked 382-219052C and associated 381-219051B markings. These markings should be photographed before purchasing a replacement. A matching base part number does not by itself prove that two boards have identical revisions, connector populations, firmware-dependent behavior, or host compatibility.
Procurement and Replacement Checks
- Confirm the exact marking 382-219052.
- Record the complete board revision and secondary PCB number.
- Confirm whether the host equipment is TTC 400 or ACC 401.
- Verify the associated 382-098602 power supply.
- Check the condition and age of the associated battery pack.
- Inspect board connectors and backplane contacts for corrosion.
- Verify battery wiring before energizing the replacement.
- Compare PCB layout and connector locations against the removed board.
- Test charging behavior after installation rather than relying only on power-up status.
- Preserve the removed board until the complete charging circuit has been validated.
Application Scenarios
- Kongsberg TTC 400 acoustic transponders
- Kongsberg ACC 401 MF acoustic control equipment
- Marine acoustic positioning equipment
- Vessel-based transponder systems
- Battery-backed marine instrumentation
- Legacy Kongsberg Simrad offshore equipment
The TTC 400 manual explicitly identifies 382-219052 as one of the main TTC 400 line-replaceable modules.
Engineer’s Guide: Field Pitfalls
Do not treat 382-219052 as the power supply.
The associated 382-098602 is the documented power supply. In ACC 401 documentation, that unit is specified as 48 VDC/1 A, 45 W. Those ratings should not be assigned to the charger board.
Check the battery before condemning the charger board.
An aged or internally damaged battery can produce charging symptoms that resemble a charger failure.
Inspect marine connectors carefully.
Salt contamination, oxidation, moisture ingress, and poor contact pressure can create intermittent charging faults that disappear temporarily after board replacement.
Verify the host system.
TTC 400 and ACC 401 share several Kongsberg part numbers, but the complete equipment architecture still needs to be confirmed.
Record revision markings.
A current listing identifies the unit as 382-219052C with 381-219051B as an associated marking. Treat the revision information as part of the procurement identification rather than ordering solely by the base number.
Do not copy unsupported electrical specifications.
The official Kongsberg spare-parts documentation establishes the board identity but does not provide a complete standalone charger specification. For a critical marine replacement, the original equipment documentation and physical board markings take priority over generic reseller data.
Frequently Asked Questions
What is Kongsberg 382-219052?
It is a Battery Charger Board used in Kongsberg’s TTC 400 acoustic transponder. Kongsberg’s official TTC 400 manual lists it as one of the unit’s main LRUs.
Is 382-219052 a power supply?
No. It is the battery charger board. The TTC 400’s separate power supply is 382-098602.
Is 382-219052 used in ACC 401?
Yes. The ACC 401 MF system parts list identifies 382-219052 as the battery charger board.
What battery is associated with the TTC 400?
The TTC 400 spare-parts list identifies 290-220142 as the battery pack.
Does 382-219052 have Ethernet or Modbus?
It is not documented as a standalone Ethernet, Modbus, or other industrial communication module. Its role is dedicated to the equipment’s internal battery-charging architecture.
What should I verify when sourcing a replacement?
Verify the complete 382-219052 marking, PCB revision, associated 381-219051 marking if present, host equipment model, connector arrangement, and the condition of the associated power supply and battery.
Procurement Note
For a legacy Kongsberg installation, 382-219052 should be sourced as a system-specific charger PCB, not as a generic battery charger. The strongest available identification comes directly from Kongsberg’s TTC 400 documentation. Before replacement, confirm the host unit, board revision, associated 382-098602 power supply, battery pack, and physical connector arrangement.
