UTC O-2 (= P-2) as MC-stepup

Cobra2 · 07:58 AM

Hello!
I have a pair UTC P-2 transformers that I would like to use as 1:15 (200 ohm) stepup.
And looking at connection-diagram & pinout, makes me confused.

It says: primary: connect to 2 & 4 + "join" 3-CT ...
Join what? 3 IS center-tap.
-same story with secondary.
Suggestions, please?

Hi, I have looked at the list and diagrams, the "join" column is just what
it says it is and you will have noticed that if there is a joining eg. X "and"y ,therefore if it list x-CT means it indicate just a center tap only.So 2 and 4 is right for 200 ohm.

So x-CT is actually x=CT, and nothing more...
