FAQ

Can I use the SCW08B-12 to power a small 12V industrial control circuit from an 18-36VDC source?

Yes, it is designed for an 18-36VDC input range and provides a constant 12V output. Its 8W rating and 0.67A output current make it a fit for low-power 12V control electronics rather than higher-load equipment.

Is the SCW08B-12 suitable for embedded 12V electronics inside compact equipment?

It can be a good fit for compact embedded designs because it measures 31.8 × 20.3 × 12.2 mm and weighs 17.5 g. The output is constant 12V at up to 0.67A, so it is intended for small 12V loads within its 8W capacity.

Can this converter support 12V automation sensors or interface modules?

It is appropriate for 12V automation electronics that need constant voltage and stay within 0.67A output current. With an 8W output limit, it is better suited to light-duty sensor or interface loads than to larger 12V devices.

How does the SCW08B-12 compare with the other SCW08B models?

All three SCW08B models are rated at 8W. The SCW08B-05 provides 5V at 1.6A, the SCW08B-12 provides 12V at 0.67A, and the SCW08B-15 provides 15V at 0.53A.

Is the SCW08B-12 suitable for outdoor or harsh-temperature use?

The operating temperature range is -40°C to +71°C, with output derated at higher temperatures per the derating curve. However, no IP rating is listed, so outdoor exposure or washdown suitability is not specified by these specs.
