Cowboy Bob, no, not on a farm. Neighbours have cockerel and chickens that wander everywhere, and at 3:00pm I didn't notice it. Now at 05:am, I could strangle the damn thing. Glad you liked the RPC, and the lathe.
Panic mode, I don't know if you read the title, but it is 415V output. Here on the eastern side of the big pond, all our three phase supplies are of that voltage. Commercial RPCs still sell well over here, especially to disillusioned inverter owners. However, both these RPCs, and the static inverters available, all have big, heavy transformers to get the output voltage required.
All the commercial RPCs I have looked at use the well known delta wired circuit such as has been around, as you say, for decades.
Now if you can point me to a 230V single phase input, 415V three phase output RPC without the transformer, I would be interested to know, maybe I can learn something else.
The inverter you link to is 230v in, 230v out. They ARE available with 415V output, but MOST of those I have seen are intended for three phase input by the original manufacturers. I have seen them "modified" by covering up the third input terminal, and sold with the original output specification still shown, without any NECESSARY de-rating.
I am also aware of some which were sold by the manufacturers as 230V in, 230V out, both with the hidden third input terminal, and the software manipulated to get the 415V output.
I am told it can't be done, but I have tested one and seen it. Still sold with the original output specs, other than the 230V being overwritten by 415V.
Don't get the idea I am expert on this, I am not, but by having a reasonable knowledge, and testing and documenting many failures and modification, I have something I am proud of, and which WORKS! Only time will tell if I succeed in "selling the plans", but I have already been asked to supply a kit. I am thinking about that, but if I do, it is more time I can't spend with my motorcycles.
