[Amps] VARIACS

[donroden at hiwaay.net]

I have several POWERSTAT  single phase variable autotransformers
120vac in / 0-140vac out @ 15 amps or 2.1 KVA .   They are motor  
driven by a SLO-SYN synchronous stepper motor with adjustable upper  
and lower limit set points.  These can be remote controlled by two  
spst push buttons, or a center-off dpst lever switch. Mount them  
behind your desk, out of the way.


One variac could step-start a 220vac linear at half voltage and ramp  
up to full voltage + a smidgen.  Brushes and brush surfaces are as  
new.  You could put one on both sides of the 220vac and start at zero  
volts.  I'm unsure of shipping and packing costs from MAIL-PRO, but  
send me a zipcode and I will get a close estimate.  $100+ ship&pack   
while supplies last.
