EL2596 | 1-channel LED strobe control terminals

The LED driver terminals from the EL2596 series contain a flexible power supply unit that supplies the LED with the required voltage and current. The terminals support applications from constant lighting to short light pulses in the kHz range. Each individual flash can be triggered in a controlled manner by the control system via the distributed clocks/timestamp function. The EL2596-xxxx terminals also feature a trigger output for camera triggering as well as high-end fast voltage and current control, e.g. for providing line scan cameras with constant illumination. Extensive real-time diagnostics, e.g. for input current/voltage and output current/voltage allow detailed monitoring of the LED light intensity. Thus, overdrive applications with short high-current pulses through the LED are possible. If a given load corridor is left, which can be defined e.g. by means of load errors, the EL259x switches off to protect the LED. Subsequent reset is possible.
