steven Posted December 9, 2005 Report Share Posted December 9, 2005 ive had a few microwave oven transformers , that i never used and the core itself is active return negative , now i was once told how to determine the outputs of a transformer and it worked so you may be able to do the same , with a multimeter set to low ohms and if you get a reading you have the secondarys , Quote Link to comment Share on other sites More sharing options...
cjk2 Posted December 28, 2005 Report Share Posted December 28, 2005 The output of a MOT is taken between the core and the only one connector on the secondary coil. There will also be a low voltage winding of a few turns of fairly big wire. This can be removed as it is likely useless. You will not be able to ge 4.2kv out of a single MOT. To do that you need a doubler which will give you around 4kvdc. Please use caution so you don't kill yourself. MOTs can be very dangerous. Also, balast it at around 1000w or you will blow a fuse.

awright Posted April 1, 2006 Report Share Posted April 1, 2006 77710, the voltage doubler is built into the oven circuit, as shown in the schematic you posted along with the picture of the transformer. Quote Link to comment Share on other sites More sharing options...
