Test conditions and notes5

1.All parameters are specified at normal input(L:5Vdc, M:12Vdc, N:24Vdc), rated load, 25℃ 70% RH ambient.
2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μf & 47μf capacitor.
3.Line regulation is measured from low line to high line at rated load.
4.Load regulation is measured from 20% to 100% rated load.
5.The final equipment must be re-confirm that it still meet EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”(as available on http://www.meanwell.com)

FAQ

Can I use the SPUN02L-12 to create a small 12V rail for industrial sensors or control interfaces from a 4.5~5.5V source?

Yes, for low-power loads that need a fixed 12V and fit within the 2W rating. This model is specified for 4.5~5.5V input and 12V output, which suits compact sensor, interface, or control circuits. It is not intended for larger 12V power demands.

Is the SPUN02L-12 a fit for embedded systems that need 12V from a 5V-class input?

It is built for that type of low-power conversion. The converter delivers a fixed, unregulated 12V output from a 4.5~5.5V input and comes in a 19.6 x 7.2 x 10.2 mm (L x W x H) package. The available output power is 2W.

Can this model work in automation equipment exposed to very hot or very cold ambient conditions?

The specified operating temperature range is -40°C to +105°C, with load derating at high ambient per the derating curve. That supports use in automation and embedded equipment with broad ambient temperature variation. The electrical application still needs to remain within the 12V, 2W output specification.

Is the SPUN02L-12 rated for outdoor use or harsh washdown areas?

No IP rating is listed in the provided specifications. The converter is rated for -40°C to +105°C operation, but the page does not specify water or dust protection. That means environment suitability is defined by temperature, not by a stated enclosure rating.

How does the SPUN02L-12 compare with the other SPUN02L models?

All listed SPUN02L versions are rated at 2W. The SPUN02L-05 is 5V, 0~400mA; the SPUN02L-12 is 12V, 0~167mA; and the SPUN02L-15 is 15V, 0~134mA. The family data shown here also includes 19.6 x 7.2 x 10.2 mm dimensions, -40°C to +105°C operation (with derating), EAC TP TC 020/2011 safety approval, and a 3-year warranty.
