CrimpOrion-Tr Smart 48/24-12
Isolated 48→24 V step-down DC-DC charger, 12 A output. Common on hybrid sailboats that run a 48 V propulsion bank AND a 24 V house / autopilot / electronics bus (Raymarine high-power radar, Lewmar 24 V windlasses). Output goes to a 24 V battery or directly to the 24 V bus.

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.
