Driver Features Large Array of Output Channels

The 5500A Solid-State Source Driver/Controller independently drives, controls, and modulates as many as 18 different solid-state sources, including combinations of LEDs, 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.

The 5500A provides independent current control to each UV-LED to achieve optimal performance and lifetime by ensuring uniform current density through the entire LED array.  Each die in the UV-LED array can be driven and modulated independently for precise exposure control in direct imaging systems. The output parameters for each source channel are set through RS-232, USB or Ethernet using a simple command set provided for user programming. Output is initiated over an external trigger.

Additionally, 5500A is also intended for technical and industrial applications such as LED lighting for machine vision, CCTV security and surveillance, and license plate recognition (LPR) for traffic enforcement or parking garage management. It provides constant current in continuous mode or pulsed mode to a minimum pulse width <20 microseconds and a maximum 15 kHz rep. rate. Drive current is selectable from 0A to 3A per channel with 10-bit resolution at a maximum compliance voltage of 6.0VDC. The 5500A system additionally includes the ability to monitor a temperature sensor that is installed on a solid-state source module, and a photosensor input for monitoring light output from specific illuminator designs
