Hi, I hope someone can help me understand the difference between to following transformer information.
I have an old Oil Fired Rayburn and the ignition transformer has failed. I have sourced a new transformer, however, the one that has been sent to me by Rayburn has a different transformer code than the one I have taken off.
I have assumed the one sent by Rayburn is the correct one, but with me not being an electrician I don't just understand the difference to the one that was on and the one I have been given. The reason I am asking is that there is over £100 difference in price.
Below I have listed the different specs of the transformers that were on and want I have been sent. All models are from the same make - Cofi
1. Is the transformer which has gone faulty
2. Is the transformer that has been sent by Rayburn as a replacement
3. Is an alternative model I could purchase at a lot less money
I would like to now want the 25% su 4' means and would the others work ok?
1. TRE820 230V 50Hz 2×4 kV 20 mA 19% su 3’ Earthed center
2. TRS1020 230V 50Hz 2×5 kV 20 mA 25% su 4′ Earthed center
3. TRS1020 230V 50Hz 2×5 kV 20 mA 33% su 4′ Earthed center
