[VAC] Re: Battery Chargers

Bill,
  I think that UniVolt is AirStream's name for whatever converter 
they're using at the moment. I've had 2 different ones here:

One had a large transformer, 2 diodes, an SCR or Triac, and a little 
printed circuit board that controlled the SCR/Triac. The board was bad, 
allowing the thing to put out full voltage (about 16), cooking the battery.

The other one also had a large transformer and 2 diodes, but also 
included a bank of 3 capacitors. It had a fuse panel on the end that 
held all the branch circuit fuses and a shunt for the ammeter. This one 
had the (in)famous "Airstream Hum", the other one was quiet.

Both were labeled "UniVolt", both came in AirStreams, but they were made 
by different manufacturers. Both crapped out and are now in the junk pile.

They also weighed a ton, the Inteli-Power weighs about 4.5#.
