XP Power SA350N503 DC-DC converter 11-15V input 6V@48A output.

Pulled from American Signal Corp LED message board. This appears to be a custom power supply for these signs. XP Power doesn't have any documentation on the model.

The sign did work and the power supply was operational at the time it was pulled.

Bench test W 12V input delivered 8V on the unloaded output terminals.
