Power Adapter MEAN WELL MPM-15-3.3 15W Input 90-264V

The MEAN WELL MPM-15-3.3 is an AC-DC single-output encapsulated medical power supply that delivers 3.3 V DC at 3.5 A (15 W). It accepts a wide input voltage range of 90–264 V AC, features PCB through-hole mounting, and provides reinforced isolation with 2xMOPP suitable for medical equipment. The unit is compact (depth 52.4 mm, height 24 mm), lightweight (56 g) and RoHS compliant.

Advantages

The MPM-15-3.3 offers a wide AC input range for global operation, a compact footprint for PCB-mounted applications, and medical-grade isolation with 2xMOPP for patient safety. Its single 3.3 V output at 3.5 A provides a stable 15 W power source while keeping overall size and weight minimal.

Suitable for

• Medical devices requiring reinforced isolation and low-voltage DC supply
• PCB-mounted embedded systems and modules
• Portable and compact equipment with 3.3 V power rail

How to use

Install the MPM-15-3.3 on the device PCB using the through-hole pins, ensuring proper solder joints and mechanical support. Connect the AC input per the device wiring diagram and route the DC 3.3 V output to the target circuit, observing polarity and load limits. Verify isolation clearances and follow the device’s layout guidelines to maintain creepage and clearance distances for medical safety.

Recommendations

Use the power supply within its specified input range (90–264 V AC) and rated output current (3.5 A). Provide adequate ventilation and avoid placing heat-sensitive components directly above the unit. For medical applications, ensure system-level compliance testing and maintain required isolation and grounding practices.
