Thanks Hero999. Can you tell me where I can find these types of transformers?
It's not a standard part. Most transformers have mains voltage primary (typically 110V or 230V) not 24V.
This transformer is used in a control card of a weaving machine. Also, is there a way to know which pins correspond to which secondary? I mean which secondary is rated to which current? All I know about this transformer is 1-2 is primary, 3-4 no pins, 5-6, 7-8, 9-10 are three secondary windings.
Yes, it should be easy to measure them with a multimeter: the secondary with the highest current rating should have the lowest DC resistance.
