Description
The Kongsberg 386690C is a critical filter-capacitor assembly specifically designed for the HiPAP (High Precision Acoustic Positioning) LPT32 (Low Power Transceiver) system. These components are essential for noise suppression and power smoothing within the sensitive sonar and acoustic positioning electronics. HiPAP systems rely on extremely clean power to maintain high-accuracy subsea positioning; any degradation in the filtering capacitors can result in signal interference, “noise” in the acoustic data, or premature failure of the sensitive transceiver modules.
Product Specifications
- Part Number: 386690C
- Associated Assembly: LPT32 (Low Power Transceiver)
- Manufacturer: Kongsberg Maritime
- Component Type: Filter-Capacitor Module (Power Conditioning)
- Application: HiPAP Acoustic Positioning Systems
- Function: Filtering electromagnetic interference (EMI), stabilizing DC supply rails, and maintaining transceiver signal integrity
- Compatibility: Designed for use with HiPAP 386691 transceiver boards and related sub-assemblies
- Construction: Industrial-grade capacitors mounted on a precision PCB/assembly for high-vibration maritime environments
Maintenance & Technical Insights
- Failure Symptoms: If this filter-capacitor assembly begins to degrade, you may notice increased noise floors in your acoustic positioning data, intermittent transceiver dropouts, or power-on self-test (POST) errors within the HiPAP control software.
- Inspection: During scheduled maintenance of the HiPAP transceiver, visually inspect the capacitors on the 386690C board for signs of bulging, leaking, or discoloration (a common indicator of “electrolytic fatigue” in marine electronics).
- HiPAP Integration: This board acts as a buffer between the raw system power and the precision signal processing stages.
