Maretron NF-NM4P-NF Marine NMEA 2000 Female to Female Mini Powertap with Fuse
A Powertap is connected to a network backbone just like any Tee but rather than connecting a device, its purpose is to provide “bus” power. Typically a Powertap is placed as central as possible between total devices on the backbone. Maretron Powertap uniquely provides two power inputs permitting doubled power provision for devices.
Features:
Connects power supply to NMEA 2000 Trunk Line in convenient plug/play fashion.
