FAQ

Can I use the SCW12B-15 to power a 15V industrial sensor or transmitter?

It can fit low-power 15V industrial sensors or transmitters that need constant voltage and stay within 15V, 0.8A, and 12W. Its specified input range is 18-36VDC, so the source side also needs to match that range.

Is the SCW12B-15 suitable for embedded or automation boards that require 15V DC?

This converter is intended for constant-voltage 15V output and can be used where the load stays at or below 0.8A and 12W. That makes it a fit for compact embedded or automation subcircuits that need a regulated 15V rail rather than a higher-power supply.

Can this model be used in a compact industrial control assembly with limited space?

Yes, its body is 31.8 × 20.3 × 12.2 mm and weighs 17.5 g, so it suits space-constrained control assemblies. The electrical fit still depends on the load requiring 15V constant voltage within 0.8A and 12W.

Which SCW12B model should I choose: 5V, 12V, or 15V?

In the SCW12B series, the SCW12B-05 is 12W with 5V output at 2.4A, the SCW12B-12 is 12W with 12V output at 1A, and the SCW12B-15 is 12W with 15V output at 0.8A. All three are constant-voltage models, so selection depends on the output voltage and current your load requires.

Can the SCW12B-15 be used in harsh temperature conditions or outdoor equipment?

Its specified operating range is -40°C to +71°C, with load derating at higher temperatures per the derating curve, so it is designed for wide-temperature use. No IP rating is listed in the provided specs, so those specs do not confirm outdoor or weather-exposed use.
