Frequently Asked Questions

Can I use the SCW08A-12 for a 12V relay or control circuit in industrial equipment?

Yes, it is suitable for constant-voltage 12V control loads when the supply feeding it is within 9-18VAC. The output is rated for 0.67A and 8W, so it fits lower-power relay and control circuits that stay inside those limits.

Is this a good fit for a 12V sensor interface or signal-conditioning module?

It can be used where the electronics require a regulated 12V constant-voltage output and draw no more than 0.67A. With an 8W rating and 9-18VAC input range, it is positioned for low-power interface electronics rather than larger 12V loads.

Can the SCW08A-12 power a small 12V automation accessory in a tight enclosure?

Yes, if the accessory needs 12V and remains within 0.67A and 8W. The unit measures 31.75 × 20.32 × 12.19 mm and weighs 0.015 kg, which helps in compact control assemblies.

What is the difference between the SCW08A-12 and the other SCW08A output versions?

The SCW08A-05, SCW08A-12, and SCW08A-15 all share the same 8W rating, 9-18VAC input range, and 31.75 × 20.32 × 12.19 mm dimensions. The difference is the output: 5V at 1.6A, 12V at 0.67A, or 15V at 0.53A.

Can the SCW08A-12 be used outdoors or in unconditioned spaces?

The stated operating temperature range is -40°C to +71°C, so it is specified for broad temperature exposure. The provided specs do not list any IP rating, so outdoor protection or sealed-enclosure performance is not specified.
