The PSUPPLY-12V12A is Blackmagic's replacement power supply for the Broadcast Videohub router, delivering 12V DC at 12A through a standard IEC mains lead. It's the part to order when an original supply fails, and worth holding as a cold spare -- Broadcast Videohub runs on twin redundant, auto-changeover power connections, so a replacement supply restores that redundancy rather than plugging a single point of failure.
