Bad Wolf SPN2K-12BA NMEA 2000 Backbone Surge Protector – Lightning & Power Surge Protection for Marine Electronics

Protect your NMEA 2000 network and critical marine electronics from lightning strikes, voltage spikes, and power surges with the Bad Wolf SPN2K-12BA Backbone Surge Protector. Designed for both data lines and 12VDC power systems, it safeguards autopilots, chart plotters, VHF radios, and other sensitive devices, ensuring reliable performance even in harsh marine environments.

Key Benefits:

  • Advanced Multi-Stage Surge Protection for NMEA 2000 Data Lines:

    • Ultra-fast TVS diodes respond instantly to voltage spikes.

    • Differential Gas Discharge Tubes (GDTs) provide robust surge absorption for long-term reliability.

  • Dedicated 12VDC Power Line Protection:

    • High-capacity Metal Oxide Varistors (MOVs) shield power lines from electrical transients and surges.

    • Isolated power protection prevents crossover noise, ensuring optimal network performance.

  • Rugged, Weatherproof Design:

    • NEMA-rated ABS enclosure is watertight, corrosion-resistant, and built for harsh marine and industrial conditions.

    • Slim, space-saving design allows flexible mounting in any orientation.

  • Easy Installation:

    • Male and female connectors allow quick integration into the NMEA 2000 backbone.

    • Optional installation in Drop Cables provides additional protection for single devices.

Installation Instructions:

Installation in the NMEA 2000 Backbone:

  1. Designed to install directly into the backbone of your NMEA 2000 network.

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

  3. Installs like a standard T-connector (without a third connection for Drop Cables).

  4. Insert the male and female connectors into the backbone where the surge protector will be placed.

Optional Installation in Drop Cable (Additional Protection):

  1. Use one user-supplied Drop Cable between the T-connector and the surge protector.

  2. Use a second user-supplied Drop Cable between the surge protector and the electronic device you wish to protect.

Why Choose the Bad Wolf SPN2K-12BA?

Protecting your marine electronics from lightning and power surges is crucial. With its advanced multi-stage design, dedicated power line protection, and rugged weatherproof enclosure, the SPN2K-12BA is the ultimate safeguard for NMEA 2000 networks, giving you peace of mind on the water.

Perfect for: NMEA 2000 backbone networks, autopilots, chart plotters, VHF radios, and all sensitive marine electronics.

Does NEMA 2000 really need a surge protector?
NEMA 2000 is vulnerable to power surges, particularly from lightning and corroded connections.
My NEMA 2000 power cable has a 3 amp fuse, but your product says it is 5 amps. Will it work for me?
Yes, even though our product is rated for more current your 3A fuse will still work ok
I have a Regal 33 Express will this work for me?
Yes, but your NEMA 2000 Backbone is longer than 20 feet so we recommend using two of these devices if possible.
Will this work on a Sailboat?
yes, any vessel that has a NEMA 2000 network system can benefit from using this device.
Where do I install this?
The device is designed to be installed in the Backbone of the network cable similar to how a T-Conenctor is installed. This device may also be used on the drop cable, this would require a drop cable between the T-Connector and the SPD and then another drop cable between the SPD and the electronic device you wish to protect.
