Power adapter MEAN WELL MPM-65-48, indoor 65 W, input 80–264 V, black, 52×87×29.5 mm

Mean Well MPM-65-48 is an indoor AC/DC power adapter that provides a regulated 48 V output at up to 65 W in a compact black housing measuring 52 × 87 × 29.5 mm. The unit accepts a wide input range from 80 to 264 V AC and is designed for applications that require a high-density, small-size mains-to-DC supply with medical-grade safety features. The adapter meets double-insulation requirements and medical safety standards for 2 x MOPP, with low no-load power consumption and high conversion efficiency.

Advantages

The adapter delivers up to 65 W from a compact footprint, combining high efficiency (up to 93%) with very low standby consumption (<0.1 W). It offers robust safety and isolation characteristics suitable for medical and industrial environments, including 4 kVAC isolation and ultra-low leakage current for patient-contact applications. Designed for reliable thermal performance and vibration resistance, the device provides stable DC output for sensitive electronics and control systems.

Suitable for

• Medical devices with BF (body contact) requirements and other patient-contact equipment
• Industrial control systems and instrumentation
• Communication and networking equipment requiring 48 V DC
• Embedded electronics and PCB-mounted power solutions in confined spaces

How to use

Install the adapter according to the equipment manufacturer’s PCB-mount or chassis-mount instructions, ensuring correct orientation and secure mechanical fixation. Connect the AC input to a compliant mains supply within 80–264 V AC and take precautions for safe grounding where required by the system design. Use proper decoupling and filtering on the DC output if the powered circuitry requires additional suppression of noise or transient events. Observe ambient temperature and ventilation limits to maintain reliable thermal performance.

Recommendations

Choose the MPM-65-48 when a compact, high-efficiency 48 V supply with medical-grade isolation is required. Verify compatibility with system leakage and insulation requirements, and follow relevant medical and safety installation standards when used in patient-contact or clinical environments.
