Description
Supply the required regulated radar power for a legacy Furuno DRS25A installation with the Furuno PSU-013 external power supply. This dedicated module is required for DRS25A radar systems and converts vessel DC power into the regulated voltage needed by the high-power magnetron scanner. Replacing a missing power module on a NavNet 3D installation? The PSU-013 is the correct companion component for a compatible DRS25A radar, not a general-purpose power converter or standalone navigation product.
Key Specifications
- Furuno PSU-013 external radar power supply unit.
- Required for Furuno DRS25A radar installations.
- Accepts 12V–24V DC vessel power.
- Provides regulated high-voltage DC output for the DRS25A magnetron radar system.
- Installed as part of the radar power and interconnect arrangement between the vessel supply and compatible DRS25A system.
- Includes internal protection appropriate to the specified Furuno radar application.
- Approximate weight: 5.5 lb (2.5 kg).
- For protected interior installation only; it is not a radar scanner, display, or network processor.
Compatibility
The PSU-013 is specifically required for DRS25A radar installations. It does not replace a DRS25A pedestal, antenna array, radar display, Ethernet connection, GPS receiver, heading sensor, or radar cable. Confirm the exact Furuno system architecture before purchase, especially when working with NavNet 3D, TZtouch, TZtouch2, or TZtouch3 equipment.
Furuno’s DRS installation documentation identifies the PSU-013 as required for every DRS25A installation, while PSU-017 is associated with DRS2D/DRS4D and PSU-012 is used in other eligible original-series DRS configurations. [772][779]
Installation Notes
Mount the PSU-013 in a dry, ventilated, accessible interior location. Use the correct vessel-power conductor size, specified circuit protection, approved radar cables, and secure strain relief. Keep wiring clear of standing water, heat, moving equipment, and high-current interference sources where practical.
Do not bypass or substitute the PSU-013 in a DRS25A system. Inspect wiring, terminals, mounting hardware, and cable seals regularly for corrosion, loose connections, moisture, damage, or overheating. Have a qualified Furuno marine-electronics installer complete wiring and radar commissioning.
Before Ordering
Verify the scanner is a Furuno DRS25A, confirm the compatible NavNet display or processor setup, determine vessel voltage, review cable requirements, and confirm adequate dry mounting space before ordering.
