Physical Dimensions
For all voltages:
The transformers will be no larger than the following dimensions:
Width: 2.63" (66.7 mm)
Length: 2.50" (63.5 mm)
Height: 2.30" (58.4 mm)
The transformer converts primary power supply voltages to the voltage
required by the direct digital controller and analog. The transformer also
serves to isolate the controller from other controllers which may be
connected to the same power source.
