Power usage of GN series goosenecks, with DPA-P phantom adapter

A client is using CK31 mic cartridges, which are spec'd to use 3mA of phantom power. These are fitted in GN series goosenecks, which the AKG website says have integrated DPA/DPA-P power adapters. I could not find a separate data sheet for these power adapters. These are part of the DAM series, and that manual describes the OPTION of wiring the adapters for external phantom power. If using an external 48V supply, it suggests 4k7 resistors --> 10mA.

My question is, if powering from a mixing desk's 48V phantom power at the mic input, how much current do the DPA-P adapters use themselves, separate from the mic cartridge?
