Maretron Mini Powertap with Fuses - NF-NM4P-NF

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 backbone.

Features:

• Connects power supply to NMEA 2000® Trunk Line in convenient plug/play fashion
• Replaceable fuses to protect bus and connected components from excessive current
• Provides two power inputs permitting doubled power provision for devices
