Hi. I am having a little issue with the osd sp70t transformer. The manual states the the transformer on a 20watt tap should have an homage of 250ohms. When I measured it with a tester, it measures 13.5ohms. I have several of those transformers and they all read the same thing.
1 Answer
Hi Jackey: The units you have are fine. This from the factory: 250 ohms needs to be measured with a frequency response of 1k at 70V with a load. Otherwise it will not be accurate. I am assuming you measured positive and negative without a load. TL/4847

How far apart are the mounting holes in the transformer flanges in case I want to mount it directly to a panel with screws, rather than use the bracket and double sided tape?
1 Answer
Hi Paul: The holes in the flange are 2 7/8 inch apart. TL/4471
