Τροφοδοτικό MEAN WELL MFM-20-15 20 W 15 V 90-264 V

The MEAN WELL MFM-20-15 is a compact AC-DC open-frame medical power supply delivering a single 15 V DC output at up to 1.4 A (20 W). Designed for PCB mounting, it accepts a wide input range of 90–264 V AC and provides two MOPP (Means of Patient Protection) isolation barriers to meet medical safety requirements. The unit is RoHS compliant and measures 49 mm in depth and 23 mm in height, with a weight of approximately 28 g.

Advantages

The MFM-20-15 offers a small footprint and low weight suitable for space-constrained equipment, stable 15 V output for consistent device operation, wide input voltage compatibility for global use, and medical-grade isolation (2x MOPP) for enhanced patient safety. PCB-mount format simplifies integration into custom medical and industrial boards.

Suitable for

• Medical devices requiring isolated low-voltage supply
• PCB-integrated equipment and embedded systems
• Industrial control modules with limited space
• Designs needing RoHS-compliant power components

How to use

Mount the MEAN WELL MFM-20-15 onto the device PCB following the manufacturer’s recommended footprint and soldering procedures. Connect the AC input to a suitable mains connector rated for the specified input range and wire the DC output to the load ensuring correct polarity. Observe clearance and creepage distances on the PCB to maintain the 2x MOPP isolation integrity. Verify output voltage and current under load during initial testing.

Recommendations

Install the module in an enclosure that preserves required ventilation and creepage/clearance for medical safety. Use proper filtering and transient protection on the AC mains where necessary and follow applicable medical device standards when integrating into patient-connected equipment.
