Operating as a true constant current source and capable of driving up to 50 LEDs in series. This driver provides a complete integrated solution that is regulated over an input range of +8V to +18V. Simple to connect and operate, this driver solution is capable of providing precise control to support dimming applications with a minimum of 3000:1. This unit features enable and intensity control inputs. MECHANICAL/ENVIRONMENTAL Weight = 20.5 grams Altitude = 35,000 ft max.
