The power routing for the display can be summarized as follows:
1. Power terminates to the display using a 120 VAC power cord that plugs
into the recessed panel on the back of the display.
2. Incoming power goes through an electrical line filter and a fuse. It is then
distributed to the transformer and the power supplies mounted to the back
sheet of the display.
3. The controller board receives about 10 VAC from the transformer.
4. The power supplies are set to 5.3 VDC. For assistance with the wiring to
the power supplies see the Schematics. Power supplies are preset. Contact
Daktronics Customer Service for the proper settings.
