KONGSBERG VT25-373-99/X9 DC Power Module (CCI DC-DC Converter)
I. Basic Information
Full model name: VT25-373-99/X9
Original manufacturer: Converter Concepts (CCI), OEM for Kongsberg (formerly Norcontrol system)
Material number: Internal part number 3800003, classified as a dedicated multi-channel isolated power supply for ETU shipboard monitoring system
Rated power: 25W level DC-DC isolated conversion module
Precise Electrical Parameters
Input Side
Input Voltage: 20–60 VDC (perfectly compatible with the 24V bus of ships, voltage fluctuation compatible with a wide range)
Maximum Input Current: 3A
Three Voltage Stabilization Outputs (with common return RET)
V1: 5VDC / 4A (power supply for CPU, logic chips, digital circuits)
V2: +15VDC / 0.5A (power supply for operational amplifiers, analog transmitters)
V3: -15VDC / 0.5A (differential analog circuits, negative power supply for instruments)
Protection Mechanism
Built-in Overvoltage OVP, Overcurrent OCP, Short-circuit self-lock protection, reverse connection anti-pinch; Fault automatic lockout, power-off restart recovery.
Mechanical and Environmental Specifications
Net Weight: Approximately 710g
Structure: Metal shielded enclosure, multi-pin straight plug terminal block wiring, cabinet embedded installation
Operating Temperature: -20℃ ~ +70℃, stable operation in ship’s high and low temperature conditions
Protection Process: PCB fully three-proof coating (damp-proof, salt spray, mold-proof), compliant with ship-specific IEC 60945 vibration / EMC standards
Isolation Strength: High-voltage isolation between input and output to eliminate interference from ship’s ground potential difference
System Adaptation Positioning
Main Supporting System: Norcontrol ETU UMS for unmanned aircraft compartments
Provides secondary voltage stabilization power supply for the entire set of chassis of the NA-1E220 (CPU/I/O motherboard) and NA-1E221 panel card as per your previous query
24V ship power → VT25-373-99/X9 → ±15V/5V → Entire control board card of ETU
Secondary Scenarios: Older Kongsberg CCI controllers, remote control units for valve positioning, small DP auxiliary I/O boxes for power supply
Application in Ship Scenarios
Built-in bulk carriers, oil tankers, container ships, PSV platform supply ships, tugboats from the 1990s to around 2012 Internal power supply for main engine control consoles, pump valve monitoring, ballast system, inert gas, fire alarm control cabinets
