SPN2K-12DA NMEA 2000 Power Cable Surge Protector for 12VDC Marine Electronics
$149.00
The Bad Wolf SPN2K-12DA is a marine NMEA 2000 power cable surge protector designed to help protect the 12VDC power feed of compatible NMEA 2000 networks from damaging voltage spikes, induced surges, and onboard power disturbances.
It installs inline between the NMEA 2000 power cable and the network T-connector to help reduce the risk of surge energy entering the network power circuit. This model protects the power connection only and does not provide data-line surge protection.
The Bad Wolf SPN2K-12DA is a marine NMEA 2000 power cable surge protector designed to help protect the 12VDC power feed of compatible NMEA 2000 marine networks.
Modern marine electronics depend on clean, reliable network power. Voltage spikes, induced voltage, electrical switching, onboard power disturbances, and nearby lightning activity can create damaging surge events on the 12VDC power side of an NMEA 2000 network. The SPN2K-12DA helps reduce the risk of surge damage entering through the network power feed.
Designed for NMEA 2000 Power Protection
The SPN2K-12DA installs inline between the NMEA 2000 power cable and the T-connector on the backbone. This allows the surge protector to help protect the 12VDC network power connection before surge energy can travel farther into the NMEA 2000 system.
This model is designed for power-side surge protection only. It does not provide data-line surge protection. For protection of both NMEA 2000 power and data/CAN bus lines, use the Bad Wolf SPN2K-12BA backbone surge protector.

FAQ
What is the SPN2K-12DA mainly used for?
The SPN2K-12DA is used to help protect 12VDC NMEA 2000 networks and similar manufacturer networks that use the same style connectors.
What does “12DA” mean?
The “12DA” version is designed for 12VDC NMEA 2000 power connection applications only. It should not be used on any voltage other than 12VDC.
Where is the SPN2K-12DA installed?
The SPN2K-12DA is installed between the 12VDC power source and the NMEA 2000 backbone. The power cable from the 12VDC power source connects to the input side of the surge protector, and a user-supplied NMEA 2000 drop cable connects between the surge protector and a T-connector on the NMEA 2000 backbone.
Is the SPN2K-12DA for 12VDC systems only?
Yes. The SPN2K-12DA is designed for 12VDC NMEA 2000 network power applications only. Do not use this surge protector on 24VDC systems, AC power, or any other voltage.

Can the SPN2K-12DA be mounted in any direction?
Yes. The SPN2K-12DA can be mounted in any direction and is bidirectional.
Does the SPN2K-12DA have status lights?
No. The SPN2K-12DA does not have status indicator lights.
Is the SPN2K-12DA waterproof?
The device itself is waterproof, but a NMEA 2000 network should not be exposed to direct moisture. Install the surge protector and network connections in a protected location whenever possible.
Can this be used on manufacturer networks similar to NMEA 2000?
Yes, the SPN2K-12DA may be used on similar manufacturer networks that use the same style connectors and compatible 12VDC network power configuration. Always verify compatibility before installation.
