Product information

Description

MEAN WELL MPM-90-48 is a 90 W indoor AC/DC power adapter designed to deliver a stable 48 V DC output from a wide input range of 80–264 V AC. Housed in a compact black enclosure (52 × 87 × 29.5 mm), this high-density module offers medical-grade safety design features, high efficiency and low no-load consumption, making it suitable for applications that require reliable, continuous 48 V power in constrained spaces.

Advantages

The unit combines a small footprint with up to 93% efficiency and a no-load power consumption below 0.1 W, reducing energy loss during idle periods. It provides reinforced insulation and 4 kVAC isolation, meeting stringent safety requirements for medical and industrial environments while maintaining low leakage current. The adapter is engineered for good heat dissipation, high EMC performance and vibration resilience, ensuring stable operation under typical telecom, industrial control and LED driver conditions.

Suitable for

  • Telecom equipment that requires a stable 48 V supply
  • Industrial control systems and automation devices
  • LED drivers and lighting control modules
  • Medical and laboratory equipment requiring medical-grade isolation and low leakage
  • Embedded systems and PCB-mounted power solutions in compact installations

Key specifications

  • Output voltage: 48 V DC
  • Output power: 90 W
  • Input voltage range: 80–264 V AC
  • Efficiency: up to 93%
  • No-load power consumption: < 0.1 W
  • Isolation voltage: 4 kVAC
  • Insulation: double insulation with medical-grade 2 x MOPP design and ultra-low leakage current
  • Dimensions (approx.): 52 × 87 × 29.5 mm
  • Operating conditions: designed for robust EMC performance and vibration resistance

How to use

Install the power adapter in accordance with device mechanical and thermal requirements, allowing adequate clearance for heat dissipation. Connect the AC input to a compliant mains source within the specified voltage range (80–264 V AC) and verify proper grounding or double-insulation arrangements as required by the receiving equipment. Connect the 48 V DC output to the load, observing correct polarity and current limits for the powered device. Follow any applicable wiring, mounting and safety procedures for PCB-mount modules or enclosed installations.

Usage recommendations

Use the adapter within its rated temperature and ventilation conditions, avoid installing near heat sources, and ensure the powered device does not draw more than the rated 90 W. For medical applications, verify that system-level protective measures and applicable standards are observed when integrating the module.
