MEAN WELL MPM Series Medical Grade Power Modules
Complete Portfolio: 5W to 90W | 2xMOPP Isolation | PCB Mount & Enclosed Types | Ultra-Low Leakage
Miniature Green Power for Medical Devices
The MEAN WELL MPM Series represents a state-of-the-art family of high-density, miniature medical power supplies. Offering both PCB-mounted modules for direct board integration and enclosed screw-terminal (-ST) models for chassis wiring, this series is engineered specifically for BF (Body Floating) patient contact medical equipment.
Core Medical Advantages
- Exceptional Medical Safety: Achieves the highest 2xMOPP (Means of Patient Protection) primary-to-secondary isolation level, ensuring maximum patient safety.
- Ultra-Low Leakage Current: Designed with an incredibly low touch current (strictly <80μA or <100μA depending on wattage), making it highly suitable for sensitive BF-type medical instruments.
- "Green" Energy Savings: Features an ultra-low no-load power consumption (as low as <0.075W) to meet the most stringent global energy efficiency regulations.
- Class II Isolation: Double-insulated design requires no ground wire (No FG), significantly simplifying device design and increasing safety in portable medical equipment.
MPM-05 to MPM-20 Specifications
The lower wattage tier is astonishingly compact. These units act as onboard power "bricks," making them the perfect solution for portable medical devices, handheld testing equipment, and dental clinical tools.
| Model Series | Max Power | DC Voltages Available | Efficiency (Max) | Leakage Current |
|---|---|---|---|---|
| MPM-05 | 5.5W | 3.3V, 5V, 12V, 15V, 24V | 82% | < 80μA |
| MPM-10 | 10.2W | 3.3V, 5V, 12V, 15V, 24V | 84% | < 80μA |
| MPM-15 | 16.6W | 3.3V, 5V, 12V, 15V, 24V | 87% | < 80μA |
| MPM-20 | 23.8W | 3.3V, 5V, 12V, 15V, 24V | 87% | < 80μA |
MPM-30 to MPM-90 Specifications
For more robust medical equipment such as mobile clinical workstations, dialysis machines, and bedside medical monitors, the higher wattage MPM series delivers increased power density in a similarly rugged, fully potted enclosure.
| Model Series | Max Power | DC Voltages Available | Efficiency (Max) | No-Load Power |
|---|---|---|---|---|
| MPM-30 | 31.2W | 3.3V, 5V, 12V, 15V, 24V, 48V | 91% | < 0.075W |
| MPM-45 | 50.4W | 5V, 12V, 15V, 24V, 48V | 92.5% | < 0.1W |
| MPM-65 | 71.6W | 5V, 12V, 15V, 24V, 48V | 93% | < 0.1W |
| MPM-90 | 99W | 12V, 15V, 24V, 48V | 93% | < 0.1W |
Stringent Protections & EMC Compliance
Global Medical Certifications
- Standards: 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 protects nearby sensitive diagnostic equipment from electromagnetic interference.
Hardware Defenses & Durability
- Fully Encapsulated: The modules are entirely potted with medical-grade silicone. 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: Boasts an incredibly wide operating temperature range from -40°C to +85°C (derating applies at highest temperatures).
Two Versatile Installation Formats
The MPM series is uniquely designed to offer engineers maximum flexibility depending on the mechanical layout of their medical device.
1. PCB Mount Type (Standard)
Designed with standard soldering pins on the bottom, intended for direct through-hole mounting onto printed circuit boards.
- MPM-05 & MPM-10: 45.7 * 25.4 * 21.5 mm
- MPM-15 & MPM-20: 52.4 * 27.2 * 24 mm
- MPM-30: 69.5 * 39 * 24 mm
- MPM-45 & MPM-65 & MPM-90: 87 * 52 * 29.5 mm
2. Screw Terminal Type (Suffix "-ST")
By adding "-ST" to the model number (available for MPM-30 through MPM-90), the unit comes pre-installed in a slightly larger plastic housing equipped with screw terminals. This is ideal for panel mounting, wire harnesses, and enclosed chassis applications.
- MPM-30-ST: 91 * 39.5 * 28.5 mm
- MPM-45-ST & MPM-65-ST & MPM-90-ST: 109 * 52 * 33.5 mm
