Run FLM03 from a DIN rail bell transformer

Question and suggestion: FLM and power supply near DIN rail is a tricky thing when there is not enough space in the switchbox. While the FLM02 can easily be run from a DIN rail 12V power supply with own fuse, of course, the AC supply is a little more tricky on the FLM03.
Would it be possible to run the FLM03 also from a bell transformer? These are available in DIN rail housing and with 8V standard they should be near enough to FLM requirements.
Possible? I will surely test it to clean up the mess with all the wall warts...
