Re: Identify transformer

Don With a primary resistance of 85 ohms @ 12 Henrys and a secondary resistance of 0.6 ohms @ 0.055 Henrys how could this possibly be a step-up power transformer?? At 7 pounds, I would guess it would have a rating of perhaps 150 V-A.? So if the full secondary is around 24 volts, the current would be around 6 amps.

Yes Walt ? I consider the turns ratio to be a primary characteristic of any transformer, but voltage ratio is usually much the same.. assuming I was guessing that you just measured it and have it on the bench. Halli seems to like? “52….” for a power transformer ???so that might be a clue , but it has no filament windings so ?? ?From the ?impedance ratios , it is likely a step up , ? ?Have a look at the saturation knee to see if it fits 120vac? ?
