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 SPBW03G-15 for low-power 15V instrumentation or control electronics?

Yes, this model provides 15V constant voltage output with 3W total power, which suits low-power instrumentation and control circuits. Its 18-75VDC input range is also useful where the source voltage can vary across a broad range.

Is the SPBW03G-15 a good fit for compact embedded systems that need 15V output?

It can fit space-constrained embedded hardware because the package is only 21.8 × 11.1 × 9.2 mm. The 15V output and 3W rating make it appropriate for small support rails rather than larger 15V loads.

Can this converter power 15V interface or auxiliary sections in automation equipment?

It is designed for constant voltage operation at 15V and 3W, so it is suited to low-power auxiliary sections inside automation equipment. The wide 18-75VDC input range also helps when system input conditions differ across platforms.

Can the SPBW03G-15 be used in outdoor enclosures or very cold locations?

The specified operating temperature range is -40°C to +85°C, so the temperature spec is broad. However, no IP rating is listed, so the product specs do not define it as an outdoor-rated converter.

What is the difference between the SPBW03G-15 and the other 3W SPBW03G versions?

The listed SPBW03G family members all have 3W power. The SPBW03G-03 is 3.3V and 700mA, the SPBW03G-05 is 5V and 600mA, the SPBW03G-12 is 12V and 250mA, and the SPBW03G-15 is 15V and 200mA.
