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 DPB09C-12 in automation equipment that needs ±12V from a 36-75V supply?

Yes, this converter is intended for low-power constant-voltage conversion from a 36-75V input range to ±12V output. At 9W, it is suited to smaller automation and control electronics rather than higher-power 12V loads.

Is the DPB09C-12 a good fit for sensor interface or signal-conditioning circuits?

It can be used where low-power circuits need ±12V rails and the available source is within 36-75V. The 9W rating keeps it in the range of compact signal, sensing, and interface functions.

Can this model power compact industrial or embedded analog subsystems?

Yes, the ±12V output is relevant for embedded and industrial analog subsystems that need bipolar rails. Its small 24 × 9.6 × 11.2 mm dimensions and 5g weight also help in space-constrained designs.

Does the DPB09C-12 work in harsh indoor environments with wide temperature variation?

The specified operating range is -40°C to +90°C, which supports use across a wide temperature span. No IP rating is shown in the provided specs, so it should not be described as outdoor-rated from this data alone.

What is the difference between the DPB09C-12 and the other DPB09C options?

The series options listed here all have 9W output. DPB09C-05 is ±5V and ±800mA, DPB09C-12 is ±12V and ±375mA, and DPB09C-15 is ±15V and ±300mA.
