Furuno Power Supply NavNet3D 4A-12A – Electrical Accessory
The Furuno PSU012 is a dedicated radar power supply for NavNet 3D, TZtouch, and TZtouch2 multi-function display systems, weighing 8.3 lbs and measuring 16 × 14 × 10 inches. Marine electronics technicians install the unit between DRS-series radar antennas and Furuno MFD displays where the MFD alone cannot power the radar directly.
