Power Reactor Core Available:

List members using pole and potential xmfrs that need external 
current-limiting reactors might find our power reactor cores of 
interest.  Measuring less than 8 x8 inches square these dual cut c-core 
reactors can be wound to control and limit current in the large 
xmfrs.  These reactor cores of high-grade supercil laminations and are 
typically gapped at 0.100 inches with plastic or nomex and then banded 
together.  These cores are laser-cut to insure low noise operation at 50-60 
Hz.

We use 120 turns of #8 AWG wire to limit pole xmfr current to 30-35 
Amperes.  We have used these as high as 60 Amperes on 220 Volt large units 
with good success.

They can also be used with 150-160 turns to limit power in potential xmfrs 
operating at 2-4 kVA range.  Some experimenters employ a tap every 10 turns 
to make them completely adjustable with taps beginning at 80 turns and then 
going up to 170 turns.  This feature allows complete adjustment and actual 
"tuning" of your power supply to the capacitor bank.

We provide "power supply tuning instructions" with each order and also some 
tips and physical dimensions on how to accomplish the winding on a standard 
acrylic box which is easy to fabricate.  Winding is done on the box which 
slides over the cores before banding them together.

End result is a neat, compact, non-saturable current control system for 5 
and 10 kVA pole xmfrs and 1.5-2 kVA potential xmfrs operating up to 60 Amperes.

Price is $125 per pair plus UPS shipment.

Please contact us off-list if ordering is of interest.  List member must 
provide photocopy of his D.L. for proof of age --- no sales to anyone under 
21 years of age -- sorry, liability issues too great.
