The 2- or 4-channel digital lighting controller from LEJ for actuating high-power LED groups allows the precise setting of the LED current, the pulse length and pulse delay across a wide range separately for each channel. Also independent for each channel, the operating modes DC, Pulsed or Switched can be selected.


The controller is configured by ethernet via the internal web server or by USB directly from the user software or a service program. All parameters are permanently saved in the LED pulse controller and can be changed during operation, i.e., they can be adapted to the needs of the application.


Independent trigger inputs make fast synchronization with the user processes possible. The flexibility of configuration, the internal monitoring of all main operating parameters, together with the active self-protection, allow the uncomplicated and efficient use in image processing, miscroscopy, a.o..
