WS500

Advanced external alternator regulator for high-output lithium charging. Drives the alternator's field with adaptive PID control and reports over J1939 CAN (RV-C / NMEA 2000), with a current shunt for charge monitoring. Supports 12–48 V systems. Powered from the battery through small fuses; carries no main charge current itself.

Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. The Crimp engine applies its ordinary continuous-load headroom, voltage-drop budget, terminal clamp, and standard fuse ladder. The 9.8 ft one-way run is a stated reference, not a universal installation prescription.

What belongs around it.

  • 19.7 ft total of 16 AWG (1.5 mm²) marine cable
  • Four 16 AWG cable lugs matched to the equipment studs
  • 1 A fuse and holder on the positive run
  • Heat-shrink, strain relief, and terminal boots sized to the cable
