Mean Well SCW12B-12 DC-DC Converter - 12W 18~36V DC in 12V out

Yes, this converter accepts 18-36VAC input and provides a regulated 12V constant-voltage output. Its output is rated at 1A and 12W, which suits lower-power 12V industrial electronics within that load range.

It can be a good fit for compact 12V automation electronics that need stable constant-voltage power and draw no more than 1A. The 12W rating makes it appropriate for smaller control and interface loads rather than larger 12V devices.

Yes, the SCW12B-12 measures 31.75 × 20.32 × 12.19 mm and weighs 0.015 kg, so it is well suited to compact embedded or control assemblies. That size is useful when a regulated 12V rail is needed in a small package.

The converter is rated for operation from -40°C to +71°C, which covers a wide temperature range for industrial indoor environments. Because no IP rating is listed in the provided specs, sealed outdoor suitability cannot be confirmed from this product data.

SCW12B-05, SCW12B-12, and SCW12B-15 all use 18-36VAC input, provide 12W constant-voltage output, and share the same 31.75 × 20.32 × 12.19 mm dimensions, 0.015 kg weight, -40°C to +71°C operating range, EAC certification, and 2-year warranty. The output options are 5V 2.4A, 12V 1A, and 15V 0.8A respectively.
