Power adapter/inverter Mean Well MFM-05-24, 5 W, 24 V output, 80–264 V input

Mean Well MFM-05-24 is a compact AC-DC power adapter/inverter that provides a regulated 24 V DC output at up to 5 W total output power. With a wide input voltage range of 80–264 V AC and a PCB-mount open-frame design, this unit is intended for low-power industrial, medical and electronic applications where a small footprint and reliable single-output supply are required. The module features reinforced isolation (2xMOPP), RoHS compliance and lightweight construction, making it suitable for panel-mounted or embedded installations.

Advantages

The device offers a stable 24 V output at up to 0.23 A from a small 42 mm depth package that weighs approximately 18 g, enabling space-saving integration into compact systems. The wide AC input range supports global mains voltages without additional converters, while the PCB mount open-frame format simplifies installation in custom enclosures or control boards. Built to meet medical isolation requirements with double MOPP insulation, the unit supports safer designs in regulated environments.

Suitable for (tasks / use cases)

• Low-power industrial control modules and sensor interfaces
• Embedded system power rails on PCBs
• Medical devices requiring reinforced isolation and low power
• Panel-mounted instrumentation and monitoring equipment
• Consumer electronics prototypes and test fixtures

How to use

Install the module on the target printed circuit board following the manufacturer’s recommended footprint and soldering guidelines. Connect the AC mains to the specified input pads and take the 24 V DC output from the designated output terminals, observing polarity. Ensure adequate creepage and clearance on the PCB for the reinforced isolation, and provide appropriate mechanical support or enclosure to protect the open-frame unit from dust and accidental contact. Verify output voltage under expected load conditions before final operation.

Recommendations

For reliable long-term operation, allow sufficient ventilation around the module, avoid operating at the upper limits of the input or output ratings continuously, and follow safety standards relevant to the application domain (especially medical installations). When integrating into patient-connected equipment, adhere to applicable regulatory requirements for isolation and leakage current testing.
