Power adapter/inverter MEAN WELL MFM-15-12, 15 W, 12 V output, 90–264 V input

MEAN WELL MFM-15-12 is a compact 15 W AC-DC power adapter/inverter offering a regulated 12 V DC output from a universal AC input range of 90–264 V. Designed as an open-frame, PCB-mount module with shallow mechanical dimensions (49 mm depth, 23 mm height) and a weight of 28 g, it is intended for low-power electronic devices and embedded systems that require reliable, space-saving power conversion. The unit incorporates medical-grade isolation with 2xMOPP and complies with RoHS sustainability requirements.

Advantages

The adapter delivers a stable 12 V output at up to 1.25 A with a total rated power of 15 W in a small footprint suitable for high-density installations. PCB-mount format simplifies integration into custom electronics or embedded systems while the open-frame design minimizes overall assembly depth. Universal input compatibility (90–264 V AC) allows worldwide deployment without additional input converters. Medical isolation (2xMOPP) and RoHS compliance support use in regulated applications where isolation and material restrictions matter.

Suitable for

• Powering low-power embedded systems and microcontroller boards
• Supply for sensors, small instrumentation and control modules
• Integration into medical devices and patient-connected peripherals requiring MOPP isolation
• High-density power assemblies and bulk deployments in industrial equipment

How to use

Mount the module directly to the application PCB following the manufacturer’s recommended layout and clearance values for open-frame power supplies. Provide the AC input via appropriate mains connectors and ensure proper Earth connection where required by system design. Verify correct polarity and regulation at the 12 V output before connecting downstream circuitry. Allow space for ventilation around the module and avoid placing heat-sensitive components directly above the unit.

Recommendations

Use this adapter in systems where a compact, PCB-mounted 12 V supply is needed; follow application notes for creepage, clearance and thermal management. For medical or patient-connected equipment, confirm complete system compliance with applicable standards and perform required safety testing.
