The Dawn VME RME-7612 is a 7U VME64 powered enclosure engineered for industrial and embedded systems requiring stable, mission-critical board support. This 19″ W × 12.22″ H × 16.35″ D chassis delivers configurable power delivery from 350W to 800W (expandable to 1000W), supporting up to 40W per slot across a 2 to 13-slot VMEbus backplane architecture. The H5052 aluminum frame, alodine coated with grain finish, weighs under 15–30 lb depending on configuration and achieves MTBF >50,000 hours at +40°C with a 13-slot backplane, 800W supply, and three-fan cooling system.
