AUR‑1BD is an UVT under‑voltage trip control device for marine generator protection system. It monitors AC supply voltage continuously, and triggers trip protection when the system voltage drops below preset threshold. Rated for 380‑440V, 50/60Hz power network. With metal mesh housing for heat dissipation, it provides reliable under‑voltage protection for ship power plant, preventing generator and electrical equipment damage caused by low‑voltage faults in vessel power distribution system.
