4.3 Power Summary
Reference Drawing:
Schematic ...................................................................................................... Appendix B
The power routing for the display can be summarized as follows.
1. Incoming power terminates at the power termination enclosure. Before leaving the enclosure,
power is sent through a circuit breaker and an RFI electrical filter.
2. Power for the controller board passes through a transformer located on the controller/power panel.
3. Depending on display size, either +6.5VDC or +9VDC power supplies are used to power the
modules. Power supplies are preset. Contact Daktronics Customer Service for the proper settings.
4. In Galaxy displays, the 9VDC power supply powers the green and blue LEDs through the 4-pin
connector. The 6.5VDC power supply powers the red LEDs and driver’s logic circuit through 2-
pin connectors.
