τροφοδοτικό MEAN WELL MFM-05-12 5W 12V 80-264V

The MEAN WELL MFM-05-12 is a compact AC-DC single-output open-frame medical power supply that delivers 12 Vdc at 0.42 A (5 W). Designed for PCB mounting, it accepts a wide input voltage range of 80–264 Vac and provides two MOPP isolation suitable for medical device requirements. The unit is RoHS compliant and has a shallow depth of 42 mm with a lightweight construction of approximately 18 g, making it suitable where space and weight are limited.

Advantages

The MFM-05-12 offers a small footprint and PCB-mount convenience for integration into medical and industrial equipment. With a wide input range (80–264 Vac) and 2×MOPP isolation, it supports reliable safety and compatibility across regions and meets environmental restrictions through RoHS compliance. Its open-frame design and low weight simplify installation into compact assemblies.

Suitable for

• Embedded medical devices requiring 12 V, low-power supply
• PCB-mounted instrumentation and control modules
• Compact industrial equipment with constrained space

How to use

Mount the MFM-05-12 directly onto the printed circuit board according to the manufacturer’s PCB layout and soldering guidelines. Connect the AC input within the specified 80–264 Vac range and take care to observe correct polarity on the 12 Vdc output. Ensure that the open-frame supply is placed to allow sufficient clearance for ventilation and that creepage and clearance distances on the PCB meet applicable medical safety requirements.

Recommendations

For medical applications, verify system-level compliance and perform required safety tests. Maintain adequate creepage/clearance, follow MEAN WELL’s recommended PCB footprint and soldering procedures, and provide appropriate fusing and transient protection on the AC input where required.
