MEAN WELL MFM Series Medical Grade Power Modules
Complete Portfolio: 5W to 30W | 2xMOPP Isolation | High Reliability PCB Mount | Ultra-Low Leakage
Miniature Green Power for On-Board Medical Devices
The MEAN WELL MFM Series is a premium family of high-density, highly reliable medical power supplies. Designed exclusively as PCB-mounted (on-board) modules, this series is engineered to be soldered directly onto the mainboards of BF (Body Floating) patient contact medical equipment, maximizing space efficiency.
Core Medical Advantages
- Exceptional Medical Safety: Achieves the strictest 2xMOPP (Means of Patient Protection) primary-to-secondary isolation level, ensuring absolute patient safety.
- Ultra-Low Leakage Current: Designed with an incredibly low touch current (strictly < 80μA across the entire series), making it perfectly suited for sensitive BF-type medical instruments.
- "Green" Energy Savings: Features an ultra-low no-load power consumption (< 0.075W) to meet the most stringent global energy efficiency regulations.
- Class II Isolation: Double-insulated design requires no ground wire (No FG), simplifying PCB layout and increasing safety in portable medical equipment.
MFM-05 & MFM-10 Specifications
The lowest wattage tier offers an astonishingly small footprint. These units act as onboard power "bricks," making them the perfect solution for handheld medical testing equipment, portable diagnostics, and dental clinical tools.
| Model Series | Max Power | DC Voltages Available | Efficiency (Max) | Leakage Current |
|---|---|---|---|---|
| MFM-05 | 5.5W | 3.3V, 5V, 12V, 15V, 24V | 82% | < 80μA |
| MFM-10 | 10.2W | 3.3V, 5V, 12V, 15V, 24V | 84% | < 80μA |
MFM-15, MFM-20, & MFM-30 Specifications
For more demanding on-board medical equipment, the 15W to 30W MFM models deliver significantly increased power density while maintaining the same rugged, potted, PCB-mount architecture.
| Model Series | Max Power | DC Voltages Available | Efficiency (Max) | Leakage Current |
|---|---|---|---|---|
| MFM-15 | 16.6W | 3.3V, 5V, 12V, 15V, 24V | 87% | < 80μA |
| MFM-20 | 23.8W | 3.3V, 5V, 12V, 15V, 24V | 87% | < 80μA |
| MFM-30 | 31.2W | 3.3V, 5V, 12V, 15V, 24V, 48V | 91% | < 80μA |
Stringent Protections & EMC Compliance
Global Medical Certifications
- Standards: Fully approved to IEC/EN60601-1 and ANSI/AAMI ES60601-1 medical safety standards (3rd Edition).
- EMC Integrity: Meets EMI Class B (EN55011) standards directly without requiring any additional external noise-filtering components. This saves PCB space and protects nearby sensitive diagnostic equipment from electromagnetic interference.
Hardware Defenses & Durability
- Fully Encapsulated: The modules are entirely potted. This ensures superior heat dissipation, resistance to harsh vibration (up to 5G), and protects internal components from clinical dust and moisture.
- Protections: Built-in, automatic-recovery safeguards against Short Circuit, Overload, Over Voltage, and Over Temperature.
- Extreme Environments: Designed to operate reliably at altitudes up to 5000 meters and across an incredibly wide operating temperature range from -40°C to +85°C (derating applies at highest temperatures).
