LED Display Power factory Product Information The high frequency of LED switching power supply is the direction of its development. Frequency makes the switching power supply miniaturized and enables the switching power supply to enter a wider range of applications, especially in the field of high-tech, which promotes the miniaturization and lightness of high-tech products. The development and application of external switching 5v 40a power supply are of great significance in saving energy, saving resources and protecting the environment. Features The 5v 40a power supply adopts the international advanced PWM control technology, which is green and environmentally friendly, and the energy quality is more stable. It is small in size, light in weight, has a wide operating voltage range, and can work normally within AC90-264V. The power supply has a 5-10 second delay detection circuit design, which can well prevent the power supply from outputting unstable high voltage at the moment of power-on, thus preventing the load from being impacted by high voltage (especially the LED light source, which can minimize the light decay caused by sudden changes in operating voltage). And 5v 40a power supply also has short circuit, overload and overvoltage protection, making the LED screen safer to use.
