FAQ

Can I use the SCW08B-05 to derive 5V for embedded control electronics from a higher-voltage source?

Yes, this version is suited to 5V constant-voltage electronics when the source feeding it is within 18-36VDC. It delivers up to 1.6A with an 8W rating, so it fits low-power embedded control hardware within those limits.

Is the SCW08B-05 appropriate for 5V monitoring or communications modules in industrial systems?

It can be used for 5V monitoring or communications modules that need constant-voltage output and draw no more than 1.6A. Its 18-36VDC input range sits between the 9-18VDC SCW08A and the 36-72VDC SCW08C versions of the 8W family.

Can this converter power a compact 5V automation board in a small enclosure?

Yes, if the board requires 5V and stays within 1.6A and 8W. The converter measures 31.8 × 20.3 × 12.2 mm and weighs 17.5 g, which is useful in compact assemblies.

What are the differences between the SCW08B-05 and the other SCW08B models?

The SCW08B-05, SCW08B-12, and SCW08B-15 all share an 8W rating, 18-36VDC input range, and 31.8 × 20.3 × 12.2 mm dimensions. Their outputs differ: 5V at 1.6A, 12V at 0.67A, and 15V at 0.53A.

Is the SCW08B-05 suitable for outdoor or high-variation temperature environments?

The specified operating temperature range is -40°C to +71°C, with output derated at higher temperatures per the derating curve. The provided specs do not list an IP rating, so outdoor or water-exposed use is not specified.
