Desktop AC/DC power supplies

Desktop AC/DC power supplies are external power adapters designed to provide direct current (DC) to electronic equipment by connecting to the mains supply via a power cord. This external design facilitates thermal management, simplifies replacement, and protects the equipment by keeping the power conversion stage outside the main device.

Advantages of External Power Adapters

  • Plug-and-play installation and quick replacement without opening the equipment.
  • High efficiency and low standby power consumption (compliant with ErP/DOE Level VI requirements in applicable models).
  • Wide range of power ratings and output voltages, with stable regulation and low output ripple (low ripple).
  • Electrical protection features against overload, overvoltage, and short circuits.
  • Robust design with options for fixed or detachable power cords.

Common Applications

  • Computing and peripherals (monitors, mini PCs, docking stations).
  • Audiovisual equipment and broadcast systems.
  • Routers, switches, and network electronics.
  • POS systems, point-of-sale terminals, and receipt printers.
  • Instrumentation and laboratory equipment.
  • IoT gateways, home automation, and security systems.

Options and Connectivity

  • Common IEC input connectors: C8 (2-pin) and C14 (3-pin, with protective earth).
  • DC outputs with barrel connectors (5.5 × 2.1 mm, 5.5 × 2.5 mm, etc.) and USB-A/USB-C options featuring USB Power Delivery on compatible models.
  • Models with interchangeable AC plugs (EU/UK/US/AU) and multi-tip DC connector kits.
  • Versions with a fixed output voltage or an adjustable output voltage range, depending on the model.

Certifications and Efficiency

Desktop power supplies are designed to comply with international electrical safety and electromagnetic compatibility (EMC) requirements, including applicable standards and approvals such as CE, UL, and FCC, as well as energy efficiency requirements such as ErP/CoC and DOE Level VI. Versions are available for regulated sectors, including models compliant with IEC 60601-1 for medical applications, depending on the model.

Usage Considerations

  • Verify the required power rating, output voltage, and current of the equipment.
  • Check the polarity and dimensions of the DC connector.
  • Ensure adequate ventilation around the adapter during operation.
