2.2  Display Power Overview

The power system for the 4203 series is significantly different than any previous series of 
Daktronics digital billboards. Each 65 Watt power supply powers two modules. In most cases, the 
module power path follows the signal path. 

Figure 3 shows a basic overview of what the power 

system looks like in an individual display section. Power to the display section enters into the 
termination panel and is redistributed to the power supplies. Refer to the layout drawing for 
display specific power distribution.
