SPN2K-12DA NMEA 2000 Power Cable Surge Protector for 12VDC Marine Electronics
$149.00
SPN2K-12DA is a 12VDC NMEA 2000 power cable surge protector designed to help protect marine electronics from lightning-induced surges and power disturbances on the network power feed. Installs between the 12VDC power cable and the NMEA 2000 T-connector to help prevent damaging surges from entering your boat’s network cabling and connected devices.
SPN2K-12DA — NMEA 2000 Power Cable Surge Protector for 12VDC Marine Networks
Protect your boat’s NMEA 2000 network power feed from damaging surges with the Bad Wolf SPN2K-12DA. This marine surge protector is designed for 12VDC NMEA 2000 systems and installs between the 12VDC power cable and the T-connector of the backbone to help stop surge energy before it can travel into your network cabling and connected electronics.
Modern marine electronics can be vulnerable to surge events caused by nearby lightning activity, electrical switching, induced voltage, and onboard power disturbances. The SPN2K-12DA helps protect important NMEA 2000 devices such as autopilots, chart plotters, VHF radios, displays, sensors, and other connected marine electronics by reducing the risk of surge damage on the power side of the network. This use case aligns with how the product is currently presented on your site.
Built for marine applications, the SPN2K-12DA is a targeted protection solution for installers and boat owners who want to improve the reliability of their NMEA 2000 system. It is especially useful where surge protection is needed at the power entry point of the network to help keep transient energy from coupling into sensitive communication and control equipment.
