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-05 to power a 5V embedded controller from a 9-36VDC industrial supply?

This converter is built for a 9-36VDC input range and provides a constant 5V output. With a 3W rating, it fits low-power embedded control and interface circuits that need regulated 5V within that power budget.

Is the SPBW03F-05 suitable for a 5V industrial sensor or monitoring module?

It can be a fit for low-power 5V sensor, monitoring, or signal-conditioning modules because it delivers constant voltage at 5V. The available output power is 3W, so the total load needs to stay within that limit.

Can this 5V converter be used in compact automation electronics where board space is limited?

The package is 21.8 x 11.1 x 9.2 mm and weighs 0.0048 kg, so it is sized for compact assemblies. It is intended for regulated 5V output in small industrial, embedded, or automation circuits up to 3W.

Is the SPBW03F-05 appropriate for outdoor or harsh-temperature use?

The operating temperature range is -40 degrees C to +85 degrees C, which supports wide-temperature operation. No IP rating is listed in the provided specs, so the product data does not identify it as weatherproof or outdoor-rated.

How does the SPBW03F-05 compare with other SPBW03F 3W models?

All SPBW03F siblings are rated at 3W and share the same 9-36VDC input family. The outputs listed are 3.3V on SPBW03F-03, 5V on SPBW03F-05, 12V on SPBW03F-12, and 15V on SPBW03F-15, with stated output currents of 700mA, 600mA, 250mA, and 200mA respectively.
