Can I use the SD-25B-12 in a 24V or 36V industrial system that needs a 12V output rail?

It can fit that use case when the available input is within the listed 19-36VAC range and the 12V load stays within 2.1A and 25.2W. The output mode is constant voltage.

Is the SD-25B-12 suitable for a small 12V automation or control module?

Yes, for small 12V automation or control loads that require constant-voltage output up to 2.1A. Its rated output power is 25.2W.

Can this converter power a 12V embedded device from a higher input range?

It is designed for applications needing 12V output from a listed 19-36VAC input range. The connected 12V device must remain within 2.1A and 25.2W.

How does the SD-25B-12 compare with the other SD-25B models?

Within the SD-25B family, SD-25B-12 is 25.2W at 12V and 2.1A, SD-25B-24 is 26.4W at 24V and 1.1A, and SD-25B-5 is 25W at 5V and 5A. The listed differences are the output voltage, output current, and wattage by model.

Is the SD-25B-12 intended for indoor or outdoor environments?

The provided specs show an operating temperature range of -10°C to +60°C, but they do not include an IP rating. That means the temperature range is stated, while outdoor exposure protection is not.
