NMEA 2000 Surge Protector SPN2K-12BA

NMEA 2000 networks are susceptible to surge damage, particularly from lightning strikes or power surges. This damage often occurs via the NMEA 2000 bus and the power supply lines, with components like autopilots, chart plotters, and VHF radios being particularly vulnerable. Surge Protection Devices (SPDs) are crucial for protection.

Installation Instructions for NMEA 2000 Surge Protector

1. Installation in the NMEA 2000 Backbone
   The surge protector is designed to be installed directly into the backbone of the NMEA 2000 network. It functions as a pass-through device with both a male and a female connector.
2. How to Install
   • The surge protector installs similarly to a standard T-connector.
   • It does not have a third connection for a Drop Cable (unlike a typical T-connector).
   • Insert the male and female connectors into the NMEA 2000 backbone where the surge protector will be placed.
3. Optional Installation in Drop Cable (for additional protection)
   • For added protection to a single electronic device on the network, the surge protector can also be installed in the Drop Cable.
   • To install in the Drop Cable:
     • Use one Drop Cable (user supplied) between the T-connector and the surge protector.
     • Use one Drop Cable (user supplied) between the surge protector and the electronic device to be protected.

Bad Wolf SPN2K-12BA Surge Protector
The Bad Wolf SPN2K-12BA is engineered to deliver advanced lightning and surge protection for NMEA 2000 data lines and 12VDC power systems. It features dedicated protection circuits for both data and power lines, ensuring comprehensive defense against electrical surges. All components are securely housed in a rugged, NEMA-rated weatherproof enclosure—ideal for harsh environments and demanding marine or industrial applications.

Advanced Multi-Stage Surge Protection for NMEA 2000 Data Lines
This high-power, Multi-stage surge protection design offers superior defense for NMEA 2000 data lines against fast, high-energy transient surges—outperforming conventional surge protectors.
The first stage utilizes ultra-fast TVS (Transient Voltage Suppression) diodes to deliver near-instantaneous response to voltage spikes. The second stage employs differential gas discharge tubes (GDTs), which provide robust surge current absorption for added protection and long-term reliability.

Dedicated Surge Protection for 12VDC Power Lines
The 12VDC power lines are safeguarded by an independent surge protection stage, designed to deliver superior defense against electrical transients and surges. This stage incorporates Metal Oxide Varistors (MOVs), known for their long-lasting reliability and high surge-handling capacity. By isolating the power line protection from the data line circuits, the design ensures optimal performance and prevents crossover noise between power and signal paths.

Durable Weatherproof ABS Enclosure
This device features a rugged, weatherproof ABS enclosure that is watertight and built to withstand harsh environments. It includes easy-to-install male and female NMEA 2000 connectors for quick and secure integration. The slim, space-saving design allows for flexible mounting in any orientation, making installation simple even in tight or constrained spaces.
