Product information

Description

MEAN WELL RPS-120S-48 is a compact AC-DC power adapter delivering 48 V DC at up to 2.5 A and a rated output power of 120 W. The unit accepts a wide input voltage range of 80–264 V AC, making it suitable for international mains environments. With its small footprint of approximately 50.8 × 76.2 × 28 mm (about 3 × 2 inches) and an open-frame design, this adapter is intended for integration into industrial equipment, electronic systems and OEM assemblies where a reliable 48 V supply is required. The product meets RoHS environmental standards and includes medical-grade isolation meeting EN 60601 with 2×MOPP where medical safety is specified.

Advantages

The adapter combines a high power density with a compact form factor, enabling space-saving installations without sacrificing output stability. A broad input range ensures compatibility with diverse mains sources, and the open-frame construction supports efficient heat dissipation in embedded applications. Compliance with RoHS and medical isolation standards provides regulatory alignment for healthcare and industrial systems.

Suitable for (tasks / use cases)

  • Industrial control systems requiring a regulated 48 V supply
  • Embedded and OEM electronic devices with constrained installation space
  • Laboratory equipment and medical devices needing medical-grade isolation
  • Telecommunications and networking equipment that operate on 48 V
  • Volume installations and panel integrations where units are installed in multiples

Key specifications

  • Output voltage: 48 V DC
  • Maximum output current: 2.5 A
  • Rated output power: 120 W
  • Input voltage range: 80–264 V AC
  • Form factor: open-frame AC-DC adapter
  • Size: approximately 50.8 × 76.2 × 28 mm (3 × 2 in)
  • Safety isolation: medical-grade isolation with 2×MOPP (meets EN 60601 where applicable)
  • Environmental compliance: RoHS

How to use

Mount the adapter on a suitable chassis or inside the device enclosure, ensuring adequate ventilation around the open-frame unit. Connect the AC input to a compatible mains source within the specified 80–264 V range using appropriate protective devices such as fuses or circuit breakers. Connect the 48 V DC output to the target load, observing correct polarity and using wiring rated for the expected current. Follow applicable safety standards and grounding practices during installation, and refer to system-level documentation for required creepage and clearance in the final assembly.

Usage recommendations

For reliable operation, provide free airflow around the adapter and avoid mounting near heat sources. Verify that the enclosure design maintains required creepage/clearance distances for medical applications and include additional filtering or surge protection if the installation is exposed to electrical transients. When deploying in volume installations, plan for service access and secure mounting to prevent vibration-related stress.
