Hello everyone....new member here in need of guidance:
I am trying to replace a dual output transformer, 230 vac primary with two independent outputs 24v and 6v, The original transformer is quite small and I', having difficulty sourcing a replacement.
I am trying to install a toroidal transformer 230vac primary with two independent secondary outputs of 12v. I have connected both secondary windings together to provide one 24v secondary output that feeds a voltage regulator circuit to give me 24vdc, and I am using this connection point (centre tap) for one off 12v output.....this output I am feeding to a voltage regulator to drop down to the required 6vdc. However these two dc outputs share a common negative on the dc side and I'm finding I get 24vac at the input to the 6vdc voltage regulator, the regulator has to work hard and gets hot.....I suspect I cant join the two negatives on the dc side and this is giving me the 24vac.........confused? I am ;¬)
oh....and this is the original configuration...
