Power adapter MEAN WELL RSD-30G-5, 30 W, 5 V, 6 A, RoHS, 60×113×25 mm

MEAN WELL RSD-30G-5 is a compact 30 W DC-DC enclosed converter that delivers a regulated 5 V output at up to 6 A from a 9–36 V DC input range. Designed to meet demanding environments, this unit provides reinforced isolation between input and output and conforms to railway standard EN50155. Its small footprint (60 × 113 × 25 mm) and RoHS compliance make it suitable for embedded electronics, industrial control panels and compact power installations where a reliable 5 V supply is required.

Advantages

The converter offers stable 5 V regulation up to 6 A with low output ripple, 4000 Vdc isolation between input and output for enhanced safety, and wide input voltage tolerance that accommodates automotive and industrial DC sources. Compliance with EN50155 ensures suitability for rail applications, while the enclosed design and compact dimensions simplify installation in confined spaces. RoHS compliance supports use in projects with environmental and safety constraints.

Suitable for

• Single-board computers and embedded controllers requiring 5 V power
• Signal converters, sensors and communication modules in rail and industrial systems
• Low-power automation modules and industrial control panels
• Battery-powered or vehicle-based systems with 9–36 V DC supplies

Key specifications

• Output: 5 V DC, maximum 6 A
• Input range: 9–36 V DC

How to use

Connect the converter to a suitable DC source within the 9–36 V input range, observing correct polarity and secure terminal connections. Use appropriate wiring and fusing on the input side to protect against short circuits and overcurrent. Mount the enclosed unit in a location that provides adequate ventilation and mechanical support; avoid obstructing any cooling surfaces. Verify output voltage under load before connecting sensitive electronics, and ensure the connected load does not exceed the 6 A maximum rating.

Recommendations

For reliable long-term operation, keep ambient temperature within the specified operating range, use twisted or shielded cables for signal-sensitive installations, and add external filtering or transient suppression if the installation is subject to heavy electrical noise or fast transients.
