Anything special about the 9V AC Reference Transformer 230V? Not available but can I simply substitute? I live in Germany. Thanks.
Yes. Its phase shift has been measured and the calibration factor is known. You can get one from Farnell in the UK.
I ordered the transformer and a switched socket through Newark. I needed the 230V transformer because there is no neutral in the subpanel that feeds my HVAC equipment.
I think that it was shipped to US Newark via the UK, so it took a while. They are showing stock on both the socket and transformer.
Thanks. I will order from UK since I live in Germany. I used Newark previously when I ran an avionics shop in Newburgh NY.
