Hello,
I'm designing a simple passive DI using a UTC A11 transformer. I'm having trouble understanding this sheet I found online regarding the transformer's terminal arrangement:
http://www.clarisonus.com/Archives/Trans/UTC_conn.pdf
I want the primary side to have an impedance of 200 ohms, which means I would have to use terminals 2 and 4 as my positive and negative output terminals of my DI (to go from hi-Z to lo-Z). But then it says something about "join 3-C.T." which I'm kind of confused about since terminal 3 IS the center tap for the primary coil. Are they telling me to connect terminal 3 to terminal 2 or 4? Or are they asking me to connect terminal 3 with terminal 7, the center tap of the secondary coil?
Let me know if anyone has any ideas
