Frequently Asked Questions
Can I use the SCWN03A-15 for 15V analog or instrumentation circuits?
Yes, if the circuit needs a constant 15V output and stays within 0.2A. This converter is rated 3W and accepts 9-18VAC input, which fits low-power instrumentation and analog control sections.
Is the SCWN03A-15 a fit for 15V signal-conditioning boards in industrial equipment?
It is a match for signal-conditioning boards that require regulated 15V constant voltage at up to 0.2A. With its 3W rating and 31.8 × 20.3 × 10.2 mm size, it is aimed at compact low-power electronics.
Can this model be used for 15V embedded test or measurement modules?
It can, provided the module runs from 15V and does not exceed 0.2A or 3W. The specified input range is 9-18VAC, so the source side also needs to stay within that range.
How does the SCWN03A-15 compare with the other SCWN03A output options?
This version outputs 15V at 0.2A with a 3W rating. Other SCWN03A siblings are SCWN03A-03 at 3.3V and 0.6A, SCWN03A-05 at 5V and 0.6A, and SCWN03A-12 at 12V and 0.25A; all are 3W units.
Can the SCWN03A-15 be used where temperatures are very low or very high?
The stated operating range is -40°C to +90°C, so it is specified for broad temperature conditions. No IP rating is shown in the specs, so indoor versus exposed outdoor use is not defined by the product data provided.
