Frequently Asked Questions

Can I use the SCW20A-15 to power 15V industrial sensors or control electronics from a 9~18V DC source?

Yes, it converts a 9~18V DC input to a constant 15V output. It can supply up to 1.33A with a total output power of 20W, which suits many lower-power industrial sensors and control devices that require 15V DC.

Is the SCW20A-15 suitable for embedded systems that need a regulated 15V rail?

It is a fit for embedded or instrumentation designs that need a fixed 15V output from a 9~18V DC source. The output limit is 1.33A, so it is best for lower-power 15V electronics rather than heavier 15V loads.

Can this model be used in compact automation equipment where board space is limited?

Yes, the housing is only 31.8 × 20.3 × 12.2 mm and the unit weighs 0.0185 kg. That compact size makes it practical for small automation assemblies that still need a 15V, 20W DC-DC converter.

Would the SCW20A-15 work for test and measurement devices powered from a low-voltage DC system?

It can be used where the available source is within 9~18V DC and the instrument needs a regulated 15V output. The constant-voltage design and 1.33A maximum output are appropriate for lighter-duty measurement and control circuits.

What is the difference between the SCW20A-15 and the other SCW20A versions?

The SCW20A-15 delivers 15V at 1.33A, while the SCW20A-12 delivers 12V at 1.67A and the SCW20A-05 delivers 5V at 4A. All three are 20W models in the same series.

Can the SCW20A-15 be used in cold or hot operating conditions?

The specified operating temperature range is -40°C to +80°C, which supports use across very cold and very warm environments. No IP rating is listed in the provided data, so the specs do not confirm direct outdoor exposure resistance.
