Note * : For proper operation the MGDI-20 module requires to install a 22µF chemical or tantalum capacitance accross output terminals.
Note** : For 9-36V input range, the current is derated at 80% at 9V and increases linearly to full current at 12V.
Note***: The ripple output voltage is the periodic AC component imposed on the output voltage, an aperiodic and random component (noise) has also to be considered. This
noise can be reduced by adding an external capacitor (typically 10nF/rated voltage depending on isolation requirement) connected between the pin Gin and the pin Gout
of the converter. This capacitor should be layed-out as close as possible from the converter.
Note *** : For load regulation characteristics from 0% to full load, please contact factory.

白光LED光衰原因之荧光粉性能的衰退 到目前,白光 LED、尤其是小功率白光 LED 的发光性能快速衰退已越来越为人们所认识。其实,盲目地夸大宣传,只能将 LED 行业引向歧途,不正视白光 LED 存在的问题,只能延缓白光 LED 应用的发展。只有正视问题、研究问题、尽早解决问题,白光 LED 才能健康、快速发展。 白光 LED 当前面临的一个主要问题就寿命问题。由于白光 LED 的价格尚很...[详细]
