FAQ

Can I use the SPU03N-12 to provide 15V for low-power industrial sensors or interface circuits?

No. The SPU03N-12 is a 12V output converter with a 21.6~26.4V input range. It cannot provide 15V. For a 15V output, you would need the SPU03N-15 model, which has the same 21.6~26.4V input range.

Is the SPU03N-12 a good fit for embedded or automation boards that need a small 15V converter?

No. The SPU03N-12 provides 12V output, not 15V. It fits embedded or automation boards that need a small 12V converter in a 19.6 x 7.5 x 10.2 mm package. The converter is rated for 3W, so it is aligned with low-power embedded or automation functions rather than larger loads. The listed weight is 2.9g.

Can this model be used in equipment exposed to very low or very high operating temperatures?

The specified operating range is -40°C to +90°C. That supports use in control and embedded equipment that sees broad ambient temperature variation. The electrical fit still needs to match its 21.6~26.4V input and 12V, 3W output rating.

Is the SPU03N-12 rated for outdoor exposure?

No outdoor protection rating is listed in the provided specs. The product does specify -40°C to +90°C operation, but there is no IP rating shown for water or dust resistance. Based on the available data, temperature performance is specified while ingress protection is not.

What are the differences between the SPU03N-12 and the other SPU03N versions?

The SPU03N series includes different output voltages. The SPU03N-05 is 5V, the SPU03N-12 is 12V, and the SPU03N-15 is 15V. All are 3W models with a 21.6~26.4V input range. They share 19.6 x 7.5 x 10.2 mm dimensions, -40°C to +90°C operating range, and a 2-year warranty.
