The Übertrager is a transformer where the number of wire turns on the primary coil equals the number of wire turns on the secondary coil. In this article, I will explain the Übertrager terminal labels.
P = Primär Wicklung (Primary Winding)
S = Seckundär Wicklung (Secondary Winding)
Primary winding:
AP1 = Anfang der 1. hälste. (Beginning of the first half.)
EP1 = Ende der 1. hälste. (End of the first half.)
AP2 = Anfang der 2. hälste. (Beginning of the second half.)
EP2 = Ende der 2. hälste. (End of the second half.)
Secondary winding:
AS1 = Anfang der 1. hälste. (Beginning of the first half.)
ES1 = Ende der 1. hälste. (End of the first half.)
AS2 = Anfang der 2. hälste. (Beginning of the second half.)
ES2 = Ende der 2. hälste. (End of the second half.)
