I have a similar configuration with DPA4060 which I can connect as follows:
- To a MIC2496 (through a CoreSound breakout cable), in which case the power to the mics comes directly from the MIC2496 (have a look at CoreSound website on how to configure the MIC2496 to feed the DPA's);
- directly to my MT 24/96, which can power the DPA4060 - see the following post:
http://taperssection.com/index.php/topic,76898.0.html - The only problem is that you don't have a MT 24/96

- Through a battery box (see the above referred post for the description of the battery box I have built, which works perfectly). This requires only two 6.2Kohm resistors and two 2.2 microfarad condenser, the difficult part is to find a 5-pins mini-XLR's to connect to the CoreSound breakout cable (which you would need anyway to interface the microDOTs) but maybe this is easier in the USA.
Please let me know if I can be of help with additional information or else. I would build a battery box for you, but transport from Italy would be expensive. Moreover I am now in the UAE for work reasons and will go back to Italy in July, which is a bit too long for you, I suppose.
