Some hint: If you can't figure out from all the previous posts, just use three of these modules and tie their outputs together, decoupled by diodes. That's a way more safe way. |

I'd be thrilled if it had a transformer. BTW Is there a way to connect something like the IRM-20-12 mentioned above with the 3 phase 4-wire input? --- End quote --- Electricity meter do not need isolated supply.
