Din rail transformer

Hardware

Ciao. I’m going to install my emonPi on a DIN rail. I’m wondering if anyone has a suggestion about which DIN rail transformer I should buy.

Thanks

PS: idea for the seller: you should add an option to buy the emonPi without transformers or with DIN rail transformers

Domestic distribution boards (“Consumer Units”) are exceedingly rare in the UK, and I have not been able to test and measure the properties of any DIN-rail transformers, so I am unable to make a recommendation. You need to be aware that the emonPi will almost certainly need careful calibration if accurate data is desired, because the properties - the no-load voltage and the phase error - will almost certainly be different to the one that the emonPi is calibrated for.
