VEL05US090-EU-JA is a desktop wall adapter suitable for AC/DC application. This wall adapter provides a reliable and efficient power supply and is a highly versatile solution for power errors or fluctuations in the AC input. It is easy to install and maintain, making it ideal for both commercial and residential applications.The VEL05US090-EU-JA wall adapter consists of two main components, namely a transformer and a rectifier circuit. The transformer serves to convert the AC voltage from ve phase to single phase 0, and the rectifier circuit provides a constant DC output voltage by converting the AC input voltage to a DC voltage.The VEL05US090-EU-JA desktop wall adapter has a universal input voltage range of 320–500 Vac and an output voltage range of 5–15 Vdc. Furthermore, the average output voltage ripple is 100mV peak-to-peak. Other features of this wall adapter include a power handling capacity of 90 W, a wide operating temperature ranging from 0°C to 35°C, and an efficiency rating of 86%.The working principle behind the VEL05US090-EU-JA adapter\'s power conversion is a combination of magnetic field conversion and rectification. In terms of magnetic field conversion, the transformer converts the AC input voltage into a single-phase AC voltage, which is then rectified by a diode bridge and other components to produce the output DC voltage. The VEL05US090-EU-JA adapter is suitable for a wide range of applications, from LED lighting and consumer electronics to industrial control systems and power supplies. Due to its reliable performance and operating efficiency, it is an ideal choice for powering equipment with precise voltage requirements.
