Data and Power Flow Diagram
Input data and power are supplied to the luminaire via the Series 200
connector on the electronics chassis. Power is directed to the voltage
selector board (VSB). The VSB provides power to the fan, and switches
the transformer primaries for the appropriate mode. The VSB also supplies
power directly to the Arc Power Supply (APS). The APS supplies
operating voltage for the lamp. Power is distributed to the low voltage
supply, which supplies DC voltage to the control boards. Control boards
receive power and data to command the main mechanical assemblies
located in the luminaire head assembly.
