Virtalähde/invertteri MEAN WELL MPM-90-48ST 90 W, sisätila, 48 V tulo 80–264 V, musta, 52×109×33,5 mm

MPM-90-48ST is a 90 W indoor AC/DC PCB-mount medical-grade power adapter from MEAN WELL. The compact module (52 × 109 × 33.5 mm) accepts a universal input of 80–264 VAC and provides a regulated 48 V output. Designed to meet EN/UL 60601 requirements, the unit offers 2×MOPP isolation, low no-load power consumption (<0.1 W), high efficiency (up to 93%), 4 kVAC isolation and RoHS compliance for use in medical and industrial environments.

Advantages

The MPM-90-48ST combines a small footprint with high power density and efficient thermal dissipation, allowing installation on PCBs where space is limited. It delivers low standby consumption and high conversion efficiency to reduce heat and energy loss. The module meets medical safety standards (EN/UL 60601) with 2×MOPP isolation and ultra-low leakage current, and provides robust EMC and vibration resistance suitable for demanding applications.

How to use

Mount the MPM-90-48ST on the target PCB according to the manufacturer’s recommended footprint and ensure proper clearance for thermal dissipation. Connect the AC input (80–264 VAC) and take the regulated 48 V output from the designated terminals. Verify polarity and secure all connections. Follow applicable installation rules for medical equipment, including grounding practices and creepage/clearance requirements as specified in EN/UL 60601.

Recommendations

Use the module within the specified input and output ratings and in an environment that allows adequate cooling. For medical applications, maintain the required creepage/clearance distances on the PCB and follow local regulations for leakage current and patient-applied equipment.
