Furuno, PSU-012 Radar Power Supply, NavNet 3D

The Furuno PSU012 Radar Power Supply is a critical component designed to provide stable and reliable power to various Furuno DRS (Digital Radar Sensor) radar antennas, particularly within the NavNet 3D, TZtouch, and TZtouch2 multi-function display (MFD) systems.

Key Description Points:

Essential for Radar Operation: The PSU012 is not an optional accessory but a required power supply unit for a wide range of Furuno DRS radars when integrated with NavNet 3D, TZtouch, and TZtouch2 MFDs. Without it, the radar antenna simply won’t function.
Compatibility: It’s specifically designed to work with various DRS series radars, including (but not limited to) DRS2D, DRS4D, DRS4A, DRS6A, and DRS12A. Its necessity can vary slightly depending on the specific MFD model (e.g., MFD8, MFD12, TZT9, TZT14, TZTBB).
Stable Power Delivery: Its primary function is to convert the vessel’s 12-24 VDC power into the specific voltage and current required by the radar sensor, ensuring optimal performance and a clear, interference-free radar image, even in demanding marine environments.
Integration with NavNet Systems: The PSU012 is integral to the NavNet 3D and TZtouch systems, which utilize advanced digital radar technology for superior target detection and clarity. It often facilitates “power sync” in these systems, ensuring the radar powers on and off in conjunction with the MFDs for seamless operation.
Mounting Options: It’s typically designed for deck or bulkhead mounting, offering flexibility for installation in various boat configurations.
Included Components: The unit often comes with necessary cable assemblies, such as a 5-meter power cable and a 5-meter LAN cable, along with fuses for protection.
Durability and Reliability: As with most Furuno marine electronics, the PSU012 is built with high-quality components to withstand harsh marine conditions, offering long-term durability and reliability.

Technical Specification

Input Voltage: 12-24 VDC (Volts Direct Current)
- This indicates it can operate from common marine electrical systems (12V or 24V).
- Note: While input voltage is 12-24VDC, the current draw will vary significantly depending on the connected radar. For example, a DRS12A might draw around 7.8 Amps at 12V and 3.7 Amps at 24V.
Output Voltage: Specific voltage depending on the radar model.
- The PSU012 converts the input DC voltage to the precise power requirements of the connected DRS radar sensor. This output voltage is not a fixed 12V or 24V, but rather optimized for the radar unit. (For reference, some higher-power radar units like the DRS25A might use a 48V output, but the PSU012 specifically provides the necessary voltage for the radars it supports, which are typically lower power than the DRS25A which uses PSU013).
