Subject: Extra large flyback transformers for sale --- for HV work


I have two dozen extra large flybacks available to anyone on the HV List that might need a few for experiments or charging cap banks.

Each super flyback contains 4,250 turns of #42 AWG on sec. with a 70 turn primary (setup for MOSFET switching at 120 VAC).  These units produce a nice 25 kV DC in oil and up to 20 kV DC (with rectifier on output) in open air.  The oil-immersed units could probably be pushed up to 30 kV DC output for short duty cycles.

We run them at 15 kV and a voltage doubler circuit (all under oil) for a nice 30 kV at 10 mA available for charging cap banks.  They work great to charge MMC Marx impulse lightning generator circuits operating at 30 kV DC per stage.

While they last --- approx 24 pcs. in stock --- at $24.95 for the ready to oil immerse units and $29.95 for the silicone impregnated and epoxy sealed units.

Add $4.85 for UPS shipping.

Email me off-list for orders to check available stock remaining.  Units only available until Oct. 10, 2003, or until they are all sold.

In photo, vertical unit on left is the large flyback.
