RE: Diagram posted (nt)

Posted by sayntjack on January 11, 2017 at 10:03:03:
Hi Steve. I'm not seeing your posted diagram but no matter. I have set up my buck circuit again & retaken measurements. Results - I'm more than a little embarrassed. My statement regarding calculation of rated winding currents of a transformer is correct - the rest, regarding current thru the primary 120 Volt winding in the buck configuration is not correct. I apologize to all. With the 60W 120 volt bulb bucked with the 120 / 6.3 V transformer to operate at 114V from the 122V incoming, the lamp current thru the 6.3V winding was 474mA and the current going into the 120V winding was 58mA. I'm scratching my head a little on this but again I apologize to all. Jack
