High-Output Alternator 24V 185A

Model 185 HPI

High-power 24 V belt-driven alternator, ~185 A output, externally regulated by an Arco Zeus / high-energy regulator for lithium charging. Field terminal is driven by the regulator; the output is fused and routed through a current shunt.

Design current185 A24 V system

Sized against ABYC E-11. Boats built to UK or EU rules answer to ISO 13297 — check these figures against it before you build. The design current is the unit's rated output. The Crimp engine applies its ordinary continuous-load headroom, voltage-drop budget, terminal clamp, and standard fuse ladder. The 3 m one-way run is a stated reference, not a universal installation prescription.

What belongs around it.

  • 6 m total of 95 mm² (3/0 AWG) marine cable
  • Four 95 mm² cable lugs matched to the equipment studs
  • 250 A fuse and holder on the positive run
  • Heat-shrink, strain relief, and terminal boots sized to the cable

Catalog profile

The manufacturer, model, ratings and terminal map are maintained as planning data in Crimp's component catalog. Confirm the current manufacturer manual, exact revision and installed nameplate before ordering or wiring.

Engine reference

Sized against ABYC E-11. Boats built to UK or EU rules answer to ISO 13297 — check these figures against it before you build. The published conductor, fuse and voltage-drop result uses the visible reference length and current basis; it is not a universal installation prescription.
