I'm back on to the immersun again, been off catching up with work... I measured the little orange transformer VTX 214-005-105 and the primary coil has gone...

Does anyone know of an equivalent transformer I could use...

I have de soldered some good ones, the readings I can get are for the larger one 9.95uf and the smaller one 102.2nf, does that sound right ???

Thank you, I did try measuring them on the board but I am getting silly readings, clearly this is not possible without the correct equipment !!

Immersun repair #1, I haven't found that yet !

The caps on the low switch side C1 and C4, I think they are all the same on the switching side !

Hey Marcus

Found this, one of your earlier posts, really good explanation and some listings of the parts..

Any idea on the caps ??

Many thanks... if you know the values of the caps it would be appreciated, it will save me taking a good one of just to measure it.....

I know someone listed the components for the high side, capacitors,zenner diode, etc, I just cannot find it....

Also what case sizing are the resistors ?

Can anyone help??

closest match I can find !!! FGH50T65UPD, the turn off and on are slower but when you are talking ns, is it that slow??

Hmm, good question. What igbts are in your immersun? Looking at the ones i ordered (FGH40T65SQD) they do appear to be discontinued; I think someone else here ordered FGH40T65SHD but they seem to be unavailable too. Looking at Mouser they do have FGH40T65HDF which has a lower saturation voltage and ...
