Intensity control is accomplished by the user providing a variable DC voltage level at pin 7 of CON1. A DC reference voltage (+5V) is available at pin 6 of CON1 for external use. Enable control is accomplished at pin 5 of CON1. All outputs are open and short circuit protected. MECHANICAL/ENVIRONMENTAL Weight = 116 grams Altitude = 10,000 ft max. Humidity < 85% non-condensing Size (L x W x H) = 9.48 IN x 2.55 IN x 0.675 IN PCB thickness = 0.062 IN Mounting Holes = 0.120 IN diameter (X6) Input Power & Control Connector = CON1 CCFL Output Connectors = CON2 – CON7 Page 1 of 2 ACB-12-1931 397 Route 281 – P.O.
