[AMRadio] UTC CG-302

 This auction is for an unused UTC plate transformer, Model CG-302.  Primary
voltage is 105, 115, 210, 220, or 230 volts AC.  Secondary AC voltage is
950-750-0-750-950 volts; or you could also say either 1900 or 1500 volts AC,
center-tapped.  DC voltages and currents with suitable rectifiers are 760 or
610 volts in a full wave center-tapped configuration at 360 mA.  In a full
wave bridge configuration there will be 1520 or 1220 volts at 250 mA.  These
are continuous ratings and with a choke-input filter, I believe.  A
capacitor-input filter will give you slightly higher voltages.  ICAS current
ratings will be higher.

The transformer is 5-5/8 inches in diameter by 7 inches high.  The bottom
flange is 5-3/4 inches square.  The terminals stand another 1/2 inch high.
The terminals require a 4 inch diameter cutout.

Condition is unused as shown in the pictures.  The top is a little scuffed
because that's how it sat on the shelf.  The terminal connections are
written on the side with a marker.  They will wipe off with a little
alcohol.

"came upon an unidentified transformer, excepting that it has a tag that
says:  CG-302"

It's a UTC commercial grade plate transformer: 950-750-0-750-950 at 360
mills.
Primary at 105, 115, 220, 230 VAC
