Test conditions and notes5

1.All parameters are specified at normal input(A:12Vdc, B:24Vdc, C: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 DPB09B-12 in industrial control equipment that needs ±12V rails from an 18-36V supply?

Yes, this model is intended for low-power constant-voltage conversion with an 18-36V input range and a ±12V output. Its 9W rating makes it a fit for small industrial control, monitoring, or interface circuits that need bipolar 12V rails rather than higher-power loads.

Is the DPB09B-12 suitable for signal conditioning or analog interface boards?

It can be a good fit for low-power analog and signal-conditioning circuits that require ±12V output. The 9W power limit means it is better suited to compact control electronics and instrumentation stages than to larger downstream loads.

Can this converter be used in embedded or automation systems where board space is limited?

Yes, its 24 × 9.6 × 11.2 mm size and 5g weight make it well suited to dense embedded and automation assemblies. It is still a 9W converter, so it is best matched to low-power auxiliary power tasks.

Is the DPB09B-12 appropriate for outdoor or harsh-temperature environments?

The specified operating temperature range is -40°C to +90°C, so it is rated for a wide temperature window. No IP rating is listed, so it is not described as an outdoor- or washdown-rated unit based on the provided specs.

How does the DPB09B-12 compare with the other DPB09B models?

Within the DPB09B series, all listed models are 9W units. DPB09B-05 is ±5V and ±800mA, DPB09B-12 is ±12V and ±375mA, and DPB09B-15 is ±15V and ±300mA.
