Bad Wolf SPN2K-12DA Marine Surge Protector – Protect Your NMEA 2000 Network

Keep your marine electronics safe from lightning strikes, power surges, and voltage spikes with the Bad Wolf SPN2K-12DA Marine Surge Protector. Designed for NMEA 2000 12VDC networks, it protects critical devices like autopilots, chart plotters, and VHF radios, ensuring reliable performance on every voyage.

Key Benefits:

  • Power Line Protection: Dedicated 12VDC surge protection with high-capacity MOVs for superior defense against electrical transients.

  • Data Safety: Isolated power line protection prevents interference with your NMEA 2000 network signals.

  • Rugged & Weatherproof: NEMA-rated ABS enclosure is watertight, corrosion-resistant, and built for harsh marine environments.

  • Easy Installation: Male and female NMEA 2000 connectors allow quick, T-connector style setup, even in tight spaces.

Installation Instructions:

  1. The surge protector installs between the power cable and backbone of your NMEA 2000 network.

  2. Functions as a pass-through device with both male and female connectors.

  3. Installs like a standard T-connector without the third connection.

  4. Designed for power connections only; it does not pass through data connections.

  5. Step-by-step:

    • Insert the male end of the power cable into the female connector of the surge protector.

    • Using a customer-supplied NMEA 2000 power cable, connect the female end of the cable into the male connector of the surge protector.

    • Connect the male end of the cable into the NMEA 2000 T-Connector of your backbone.

Protect your boat’s electronics and avoid costly damage. The Bad Wolf Marine Surge Protector is the essential solution for lightning and surge protection on the water.

Perfect for: Autopilots, chart plotters, VHF radios, and all NMEA 2000 marine electronics.
