## Summary description

MEAN WELL RSD-300F-5 is a 300 W power adapter/inverter with an input voltage range of 50.4–93.6 V and a fixed 5 V output. Compact metal housing measures 97 × 216 × 40 mm. Designed for converting higher-voltage DC sources to a stable 5 V supply for industrial equipment, embedded systems, and telecommunications. RoHS compliant; sold in packs of 12.

## Long 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.
