Product information

Description

MEAN WELL RSD-300F-5 is a 300 W DC-DC enclosed converter designed to convert higher-voltage DC sources into a stable 5 V output. The unit accepts a wide input range suitable for vehicle, railway and industrial DC systems and provides a regulated +5 V at high current in a compact metal housing measuring 97 × 216 × 40 mm. The converter meets EN50155 railway standard requirements, offers 4000 Vdc input-to-output isolation and is RoHS compliant.

Advantages

The RSD-300F-5 delivers high power density with a fixed 5 V output capable of supplying up to 42 A. Its wide input range supports common industrial and transportation battery voltages while the robust metal enclosure provides efficient thermal conduction and mechanical protection. Compliance with railway standard EN50155 and high isolation voltage ensure safe operation in demanding environments. The compact footprint facilitates installation where space is limited.

Suitable for

  • Industrial equipment requiring a stable 5 V DC rail
  • Embedded systems and single-board computers with high current needs
  • Railway and mass transit electronics compliant with EN50155
  • Telecommunications power supplies and control cabinets
  • Vehicle and mobile power systems with elevated input voltages

Key specifications

  • Power output: 300 W
  • Input voltage range: 50.4–93.6 V (note: device supports similar wide DC ranges up to 100.8 Vdc in related datasheets)
  • Output voltage: +5 V DC
  • Maximum output current: 42 A
  • Isolation voltage (input to output): 4000 Vdc
  • Compliance: EN50155 (railway standard)
  • Compliance: RoHS
  • Enclosure: metal; dimensions 97 × 216 × 40 mm

How to use

Install the converter in a well-ventilated location and secure it mechanically following manufacturer mounting recommendations. Connect the DC input terminals to an appropriate higher-voltage DC source within the specified input range, observing polarity. Connect the +5 V output and ground to the load, ensuring the load current does not exceed the rated 42 A. Verify proper wiring and grounding before energizing. Allow the unit to cool under load and avoid obstructing airflow around the metal housing.

Usage recommendations

For reliable long-term operation, use input sources with stable voltage within the specified range, provide adequate heat sinking or airflow when operating near full load, and incorporate appropriate upstream protection such as fuses or circuit breakers. When used in railway or vehicle applications, follow relevant installation standards and verify EMC/EMI requirements for your system.
