## Summary description

Mean Well RSD-30H-3.3 is a 30 W power adapter/inverter with wide input range 40–160 V and fixed 3.3 V output capable of 6 A. Compact dimensions (60 × 113 × 25 mm) suit DIN-rail or embedded installations. RoHS compliant, intended for industrial and embedded electronics requiring stable low-voltage power from a wide DC input.

## Long description

Mean Well RSD-30H-3.3 is a compact 30 W DC-DC enclosed converter designed to deliver a stable 3.3 V output at up to 6 A from a wide DC input range of 40–160 V. The unit meets railway standard EN50155 and provides 4000 VDC input-to-output isolation, making it suitable for industrial and embedded electronics that require reliable low-voltage power in constrained spaces. With RoHS compliance and a small footprint (60 × 113 × 25 mm), this power adapter/inverter fits DIN-rail or embedded installation scenarios where space efficiency and electrical safety are important.
Advantages
The RSD-30H-3.3 offers a wide input range that supports varying supply voltages while maintaining a regulated 3.3 V output at 6 A. Its 4000 VDC I/O isolation enhances safety and noise immunity between input and output circuits. Conformance to EN50155 and RoHS indicates suitability for rail applications and compliance with hazardous-substance limits. Its enclosed construction and compact dimensions enable straightforward mounting in industrial enclosures or on DIN rails without sacrificing power density.
