URB4805S-3WR3 Frequently Asked Questions (FAQs)

  • MORNSUN recommends a PCB layout with a large copper area connected to the tab of the device, and multiple vias to dissipate heat effectively. A minimum of 2oz copper thickness is recommended.
  • Yes, the URB4805S-3WR3 is designed to withstand vibrations up to 10G peak acceleration, making it suitable for use in industrial and transportation applications.
  • To ensure EMC, MORNSUN recommends using a metal enclosure, keeping the input and output cables as short as possible, and using EMI filters or shielding if necessary. Additionally, the converter should be placed at least 10mm away from other components.
  • MORNSUN provides a derating curve in the datasheet, which shows the recommended output power reduction at high temperatures. For example, at 80°C, the output power should be derated by 20% to ensure reliable operation.
  • Yes, the URB4805S-3WR3 can be used in a redundant or parallel configuration, but MORNSUN recommends consulting with their application engineers to ensure proper design and implementation.
