Power adapter MEAN WELL MPM-20-24 20W 24V 90-264V

The MEAN WELL MPM-20-24 is an AC-DC single-output medical encapsulated power supply designed for printed circuit board mounting. It accepts a wide input voltage range of 90–264VAC and provides a regulated 24V DC output at 0.9A (20W). The compact module is RoHS compliant, measures 52.4 mm in depth and 24 mm in height, and weighs approximately 56 g. It includes two MOPP isolation barriers suitable for medical applications and is intended for reliable low‑power electronic use.

Advantages

The unit delivers a stable 24V/0.9A output in a compact, encapsulated package suitable for PCB through‑hole mounting. Wide input range (90–264VAC) allows global use without additional input converters. Two MOPP insulation barriers provide enhanced safety for medical equipment. Lightweight construction and small footprint simplify system integration where space is limited.

Suitable for

• Medical devices and equipment requiring reinforced isolation
• Embedded systems and industrial control boards
• Laboratory and diagnostic instruments with 24V supply requirements
• Replacement or upgrade of compact PCB-mounted power modules

How to use

Mount the MPM-20-24 securely to the PCB using the through‑hole pins, observing the manufacturer’s recommended footprint and soldering process. Provide appropriate airflow and avoid covering the encapsulated case to maintain thermal performance. Connect the AC input to a properly fused mains source within the 90–264VAC range and route the 24V DC output to the load, ensuring polarity is correct. Follow applicable medical and safety standards when integrating into patient‑connected equipment.

Recommendations

Operate the module within its rated input and output limits, ensure proper creepage and clearance on the PCB for medical applications, and verify isolation requirements (2x MOPP) against your system’s certification needs. Use suitable fusing and transient protection on the AC input for additional safety.
