Power adapter/inverter MEAN WELL RSD-30H-24 — 30 W, 24 V output, 40–160 V input, RoHS

MEAN WELL RSD-30H-24 is a compact DC-DC enclosed converter providing a regulated 24 Vdc output at up to 1.25 A from a wide 40–160 Vdc input range. Designed for installations where space is limited, this 30 W power adapter/inverter meets railway standard EN50155 and offers 4000 Vdc input-to-output isolation. The unit measures 60 × 113 × 25 mm and is compliant with RoHS requirements, making it suitable for industrial control, telecommunications and embedded systems that require a stable 24 V supply.

Advantages

The enclosure delivers a stable 24 V output with up to 30 W continuous power in a small footprint, ensuring reliable operation in constrained spaces. A wide input range of 40–160 Vdc supports a variety of DC power sources and transient conditions. Conformance to railway standard EN50155 and high isolation voltage between input and output improve safety and electromagnetic compatibility for transport and industrial environments. RoHS compliance reduces hazardous substances in the component design.

How to use

Install the converter in a location with adequate ventilation and secure it according to the enclosure mounting recommendations. Connect the DC input within the specified 40–160 V range and verify polarity before powering the unit. Connect the 24 V output to the downstream load, ensuring the total current draw does not exceed 1.25 A. Observe the device’s ambient temperature and mounting orientation limits from the manufacturer documentation to maintain performance and longevity.

Recommendations

For reliable operation, provide protection against input transients and overcurrent at the source, and route power and signal wiring to minimize electromagnetic interference. Use appropriate fusing or circuit protection on both input and output lines and follow EN50155 installation practices when deploying in railway or transportation applications.
