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
