Voeding/adapter MEAN WELL RSD-30H-5 — 30W, 5V uitgang, 40–160V ingang, 60×113×25mm

MEAN WELL RSD-30H-5 is a compact DC-DC enclosed converter that delivers 30 W of regulated power with a 5 V DC output at up to 6 A. Its wide input range of 40–160 V DC and robust 4000 V DC input-to-output isolation make it suitable for demanding industrial and transportation applications. The unit is designed to conform to railway standard EN50155 and meets RoHS requirements. Its small footprint (60×113×25 mm) allows installation in space-constrained equipment while providing stable power for control electronics and communication modules.

Advantages

The converter provides a stable, regulated 5 V output with sufficient current for small PLCs, sensors and onboard electronics. High isolation voltage enhances safety and prevents interference between input and output circuits. Compliance with EN50155 ensures suitability for railway and vehicle applications where vibration and environmental resilience are required. The enclosed design offers protection against dust and accidental contact, and the compact dimensions simplify integration into existing systems.

Suitable for

• Powering control electronics and small programmable logic controllers (PLCs) in vehicles and industrial machinery
• Supplying sensors, data acquisition modules and communication devices requiring 5 V DC
• Use in railway applications and other transport systems conforming to EN50155
• Embedded systems and compact enclosures where a wide input voltage range is needed

How to use

Install the converter in a location that allows adequate ventilation and protects the unit from excessive heat, moisture and mechanical shock. Connect the DC input within the specified 40–160 V range, observing correct polarity. Connect the 5 V DC output to the load, ensuring the combined load current does not exceed 6 A. Follow grounding and isolation practices appropriate for the installation and verify the system against relevant electrical and safety standards before commissioning.

Recommendations

For reliable long-term operation, avoid continuous operation at the maximum rated load in high ambient temperatures; provide additional cooling or derate the load when installed in confined or high-temperature environments. Verify compatibility with vehicle or railway power systems and ensure proper surge protection where transient voltages may occur.
