EA LED55X46-B Led-lighting for EA DOGM..colour: blue LED LIGHTS 7 different versions are available for individual backlighting: white, yellow/green, green, blue, red, amber and a full color version. With the monochrome illuminators, 3 separate LED paths are available in each case, which can be used for optimum adaptation to the system voltage can be connected in parallel or in series. This means that most lighting systems can be operated alternatively with 3.3V or 5V! To operate the backlight we recommend a power source (e.g. CAT4238TD) or an external series resistor. for current limitation. This is calculated from R=U/I. For an optimal lifetime we recommend the use of a power source. The service life of the yellow/green, red and amber-colored illumination is 100,000 hours, that of white and blue illumination is significantly lower. We recommend dimming or switching them off whenever possible. Attention: Never operate the lighting directly at 5V/3.3V; this can lead to the immediate destruction of the LED's! Note derating at temperatures >25°C. https://elecena.pl/product/9718226/ea-led55x46-b-led-lighting-for-ea-dogm128-52-x-32-mm-blue 2017-08-06 https://elecena.pl/product/9718226/ea-led55x46-b-led-lighting-for-ea-dogm128-52-x-32-mm-blue 2018-03-06 https://elecena.pl/product/9718226/ea-led55x46-b-led-lighting-for-ea-dogm128-52-x-32-mm-blue 2018-12-17 https://elecena.pl/product/9718226/ea-led55x46-b-led-lighting-for-ea-dogm128-52-x-32-mm-blue 2021-05-05 https://elecena.pl/product/9718226/ea-led55x46-b-led-lighting-for-ea-dogm128-52-x-32-mm-blue 2021-12-23 https://elecena.pl/product/9718226/ea-led55x46-b-led-lighting-for-ea-dogm128-52-x-32-mm-blue 2022-09-24 https://elecena.pl/product/9718226/ea-led55x46-b-led-lighting-for-ea-dogm128-52-x-32-mm-blue 2023-01-06
