Test conditions and notes5

1.All parameters are specified at normal input, rated load, 25℃ 70% RH ambient.
2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1uf & 47uf capacitor.
3.Line regulation is measured from low line to high line at rated load.
4.Load regulation is measured from 10% to 100% rated load.
5.Please prevent the converter from operating in overload or short circuit condition for more than 30 seconds.

FAQ

Can I use the SKA15B-12 for a 12V industrial control device?

This model delivers constant 12V output at up to 1.25A, with 15W total power. It is suitable for 12V control electronics that stay within that current and power limit and use the listed 18-36VDC input range.

Is the SKA15B-12 a good fit for 12V automation relays, interfaces, or communication modules?

It can support 12V automation electronics that need stable constant-voltage power and draw no more than 1.25A. The key selection points are the 12V output, the 15W rating, and the listed 18-36VDC input specification.

Can this converter power a small 12V embedded or IT device inside equipment?

Yes, if the device requires regulated 12V and its load stays within 1.25A and 15W. Its 50.8 × 25.4 × 11.27 mm dimensions also make it easier to use where board or enclosure space is limited.

Is the SKA15B-12 suitable for outdoor installations or unsealed areas?

The operating temperature range is specified as -40°C to +71°C, so the temperature spec covers demanding conditions. However, no IP rating is listed, so the provided data does not identify this model as outdoor-rated or water-resistant.

How does SKA15B-12 compare with the other SKA15B output options?

The SKA15B family shares the same 15W rating and 18-36VDC input range, but output voltage and current vary by model. SKA15B-033 is 3.3V at 3A, SKA15B-05 is 5V at 3A, SKA15B-12 is 12V at 1.25A, and SKA15B-15 is 15V at 1A.
