ILP toroidal transformer type numbers

[jlinkels]

Sometimes I see people looking for type data of ILP toroidal transformers.


This is an old sheet. I post it here before the mice eat the rest of the paper.


In Dutch Type nummers ILP ringkern trafos.

I have an old ILP 52017. It isn't shown in your list, but it does have a 51017. The 5 seems to denote 160VA and the 17 infers two 30V secondaries. I've weighed my transformer and it is 1.8kg, exactly the same as they list for the 51017. It also has two secondaries which measure 31.3V open circuit with a resistance of 0.5R. Ignoring leakage effects, etc, that gives 30V o/p at the rated load of 2.67A. So it does seem to be very close to the 51017. Anybody knows how the 52017 may differ?

It is probably a difference in primary configuration. 230V vs. 2x120V, or something along those lines.

Good idea, you are probably correct.
