NMEA 2000 Power Isolator (80-911-0137-00)
The 80-911-0137-00 is a specialized marine-grade NMEA 2000 power isolator designed to electrically isolate power segments within an NMEA 2000 (N2K) or CZone network backbone while allowing CAN bus data signals to pass uninterrupted. Installed inline using standard Micro-C connectors, this component breaks the 12V DC power conductors between network powered segments to prevent power crosstalk, ground loops, and potential damage caused by multiple independent power sources feeding the same bus.
Essential for complex installations, engine gateway integrations, or dual-battery bank networks, the power isolator allows power to be injected independently on either side of the adapter without affecting seamless data flow across chartplotters, instrument displays, and sensors.
Key Features
-
Selective Power Isolation: Breaks internal 12V DC positive and ground lines while maintaining 100% signal continuity across data communication pairs.
-
Prevents Ground Loops & Voltage Cross-Feeds: Protects sensitive network modules when bridging distinct battery banks or connecting engine gateways with internal power outputs.
-
Micro-C Standard Interface: Standard 5-pin male to female threaded connectors thread directly into network T-connectors, drop cables, and backbone runs.
-
IP67 Submersible Waterproofing: Rugged, fully sealed construction protects internal connections from moisture, engine room grime, and salt mist.
-
Plug-and-Play Installation: Simple inline insertion eliminates the need to manually strip or cut power wires inside network harnesses.
