Hi,
I salvaged a 220V to 24V transformer from a broken UPS. I would like to rewire this to use with chemelec's inverter but need the transformer to be centre tapped at 12V - 0V - 12V . Can one calculate the turns or is it better to strip the winding and keep count?
Am I correct in stating that if I could find the middle of the winding and take a tap off from there that I would then have my 12 - 0 - 12 from a 0 -24?
Finally, what would the permissable current density A/mm2 be for such a transformer?
Thanks
Andrew
