Mean Well RSDW08F-03 DC-DC Converter - 8W - 3~36V in 3.3V out

This model is intended for constant-voltage 3.3V output applications where the load stays within 8W and 2A. Its listed 3-36V input range also fits systems that need a wide input window on low-voltage industrial equipment.

It can fit embedded designs that need a regulated 3.3V rail up to 2A and 8W. The product also lists 4000VDC isolation, which is relevant in systems where isolated power conversion is required.

The unit lists compliance with EN50155 and EN45545 railway standards, so it is aimed at railway-related electronic applications. It also combines that with a 3.3V constant-voltage output, 8W power rating, and a 3-36V input range.

It is designed for compact assemblies, with dimensions of 31.8 × 20.3 × 10.2 mm and a 1U low-profile, half-encapsulated construction. That makes it relevant for dense embedded or control hardware where board space and height matter.

The specified operating temperature range is -40°C to +85°C, which supports use in demanding temperature environments. No IP rating is listed in the provided specs, so outdoor exposure or washdown suitability cannot be confirmed from this data alone.

Within the RSDW08F series, all listed siblings are 8W models with the same form factor, but they differ by output rating: RSDW08F-03 is 3.3V at 2A, RSDW08F-05 is 5V at 1.6A, RSDW08F-12 is 12V at 666A, and RSDW08F-15 is 15V at 530A. The series also shares the same 3-36V input family and low-profile package style.
