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 DPB09A-12 for industrial analog or sensor interface boards that need dual 12V rails?

Yes. This model accepts 9-18VDC input and provides constant-voltage ±12V output. With a 9W rating and ±375mA output current, it fits low-power industrial analog or sensor interface sections that require ±12V.

Is the DPB09A-12 appropriate for embedded test and measurement electronics?

It can be a fit for embedded measurement electronics that need constant-voltage ±12V rails from a 9-18VDC source. The unit is rated at 9W and comes in a 24 × 9.6 × 11.2 mm form factor.

Can this converter be used in automation modules with limited internal space?

Yes. The converter measures 24 × 9.6 × 11.2 mm and weighs 5g, so it is suited to compact automation or control assemblies. It provides ±12V constant-voltage output at 9W.

Will the DPB09A-12 handle cold and hot equipment environments?

The specified operating temperature range is -40°C to +90°C, which supports wide-temperature industrial use in protected equipment. Because no IP rating is provided, it is best used inside enclosures rather than exposed outdoor locations.

How does the DPB09A-12 compare with the other DPB09A models?

The DPB09A-05, DPB09A-12, and DPB09A-15 all share a 9W rating and 9-18VDC input range. Their outputs differ: ±5V at ±800mA, ±12V at ±375mA, and ±15V at ±300mA respectively.
