Test conditions and notes5

1.All parameters are specified at normal input(F:24Vdc, G:48Vdc), 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 10% 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 SPBW03F-12 to run a 12V automation interface from a 9-36VDC control supply?

This model accepts 9-36VDC input and provides a constant 12V output. Its 3W rating makes it suitable for low-power automation interface boards and control electronics that need regulated 12V within that power limit.

Is the SPBW03F-12 a good fit for low-power 12V industrial sensing or relay logic circuits?

It is intended for constant-voltage 12V output and can support low-power industrial sensing or relay logic sections that stay within 3W. The compact body also suits dense control assemblies.

Can this converter be used in embedded equipment that needs isolated 12V rail conversion in a small footprint?

The unit measures 21.8 x 9.2 x 11.1 mm and weighs 4.3g, so it fits compact embedded hardware layouts. It provides a regulated 12V output from a 9-36VDC input range with a total 3W capacity.

Will the SPBW03F-12 handle cold or hot enclosure conditions?

The specified operating temperature range is -40 degrees C to +85 degrees C. No IP rating is provided, so the specs support temperature review but do not confirm outdoor exposure or washdown protection.

What are the main differences between the SPBW03F-12 and the other SPBW03F versions?

The SPBW03F series keeps the same 3W platform while changing output voltage and listed output current. The sibling outputs are 3.3V at 700mA, 5V at 600mA, 12V at 250mA, and 15V at 200mA across SPBW03F-03, SPBW03F-05, SPBW03F-12, and SPBW03F-15.
