Product information

Description

Mean Well RSD-300E-12 is a 300 W DC-DC enclosed converter that delivers a regulated 12 V DC output from a wide DC input range. Designed for industrial and telecom environments, it accepts input voltages from 25.2 to 46.8 V (typical operating range stated as 21.6–50.4 VDC), supplies up to 22.5 A at 12 V and meets railway equipment requirements including EN50155. The unit features reinforced isolation between input and output up to 4000 VDC and a compact form factor (97 × 216 × 40 mm) suitable for mounting in equipment racks and control cabinets where stable 12 V power is required.

Advantages

The RSD-300E-12 provides a stable regulated 12 V output with high efficiency for a 300 W class DC-DC converter, wide input voltage acceptance for flexible system integration, and certified compliance with railway standard EN50155 for reliable operation in rolling stock and other demanding installations. Reinforced 4000 VDC input-to-output isolation enhances safety and protects downstream electronics. Its compact, enclosed housing supports straightforward installation in confined spaces and rack-mounted systems.

Suitable for

  • Industrial control systems requiring 12 V DC power
  • Telecom and network equipment operating from higher voltage DC buses
  • Rolling stock and railway electronics meeting EN50155
  • Embedded systems and cabinets where space is limited
  • Backup power systems and DC power distribution racks

Key specifications

  • Output voltage: regulated 12 V DC
  • Output current: up to 22.5 A (300 W class)
  • Input voltage range: wide DC input, nominally 25.2–46.8 V (operating 21.6–50.4 VDC)
  • Isolation: input-to-output reinforced isolation up to 4000 VDC
  • Standards: complies with railway EN50155 requirements
  • Envelope: enclosed converter suitable for rack or cabinet mounting
  • Dimensions: 97 × 216 × 40 mm
  • RoHS compliant

How to use

Install the RSD-300E-12 in a suitable rack or enclosure, observing manufacturer guidance for ventilation and secure mounting. Connect the DC input from a compatible supply within the specified input range, ensuring correct polarity and adequate wiring for the expected current. Connect the 12 V DC output to the load, verifying that the combined load does not exceed the rated output current. Observe isolation requirements when integrating with other systems and follow EN50155-related installation practices when used in railway applications.

Usage recommendations

Ensure adequate cooling and clearance around the unit to maintain efficiency and prolong service life. Use appropriately sized wiring and fuses on both input and output circuits. When deploying in railway or transport applications, follow applicable EN50155 installation and environmental guidelines and perform regular maintenance checks to confirm secure connections and proper operation.
