Innovations in Optics, Inc. introduces the 5500A Solid-State Source Driver/Controller to independently drive, control and modulate as many as 18 different solid-state sources, including combinations of LEDs and LDs and even IR VCSEL arrays.  The 5500A Solid-State Source Driver/Controller provides precise, independent, constant current control up to 3A per source channel to achieve optimal performance. Its ground based design is configured for common cathode LED or LD devices which allows for multiple channels to be run in parallel for a combined current of up to 54A.
