I Have an issue with an electric gate motor, it originally had a Toroidal 250va 13.5V. Naturally this is an unusual sized transformer and the space allocated makes a replacement difficult.
The Unit is marked as having a max capacity of 200W.
I could get a 225VA/15V TX that will not fit and will require me to put it in a custom enclosure which is just a pain or i could potentially get two Toroidal transformers and put them in // 100VA/15V.
I Understand its not 13.5V but with the fluctuation in grid supply i do not believe 1.5V will make much of a difference, it also appears they rectify this voltage so i am assuming there is a regulator somewhere. TAU K125M https://www.automatismes.net/doc/Notice%20TAU%20K125M.pdf
The only concern I have with connecting them in // is checking for circulating currents, as it's been a long time ago since I conducted this test and just wanted to double check. My Primary voltage here is 230v
Primary would be Blue = Neutral, (Grey + Violet), Brown Active
Secondary would be join Yellow + Red together and measure voltage across Black and Orange if i get a reading of 0 that would indicate i am in phase and no circulating current.
Now the question that i have coming around to the second transformer what would that test look like?
I also find some conflicting information on the unit itself. The manual says 50W but the name plate reads 200W. looking at the motor it is a MP56M. So i am going to connect my Variac (500VA) to the unit and test it under load to see what it actually pulls, as i am wondering if this transformer was just oversized to begin with.
