Transformer issue
HI,
Sorry if this sounds stupid but what exactlly am i doing wrong, I am trying to test the voltage ouput of some transformers i recent found. They are rated as 43v secondaries and have 2x 120v primaries. Since the output volatge would be too high instead of running the primaries after each other to make a normal 240 input i have been trying to run them in parraell,. The issue is i cannot test even one of the units, I plug one in with nothing attached and it blows the 13a mains fuse, i then though maybe it needs some load the other end so i rigged up a bridge rectifer and with 1 ohm 5 watt resistors on the output ( read somewhere this stops in rush current blowing fuses) going into a big capacitor. Flick switch again, transformer humms for a couple of seconds and then the bloody 13 a fuse goes again. They are bg transfomers have no VA rating but they weight 3 kilos each, any ideas on how i can get the thing up long enough to do some tests. phil |
I'm not positive about what you a saying but, I would think you would wire in parallel for 120 and series for 240.

OK, I gotta ask!
How do you guys get those quotes in the boxes??? I've never been able to figure it out! If it had wires I'd have a better chance! |
let me try to get it out of a box:
\[quote\] text in the box \[/quote\] if you see \ chars there, just remove them. i have no idea if phpbbb supports escaping of things. alternatively, click on the quote or list buttons. |

I think wiring primaries of both transformers in series(with each trafo's primaries wired in series too) could be a possibility to reduce output voltage twice.The ouput power would probably decrease.

Scr_w it! :-)

How bout each in parrallel then sereised?
