  • Power rating of T6

    Isn't the coilcraft T6 transformer only rated at 630ma??
    so therefore on Sproggys circuit, you can't draw 1.3amps on the +12volts and 200ma on the -12v and 5v combined?? or, did I miss something again..

        I don't know... I've seen him make some very helpful posts. Of course I've seen some lame ones too, but it doesn't bother me. He's helped me more than he has hurt me.

        Anyway. I'm not sure about the rating of the T6 (the datasheet didn't mention anything but temperature rating and dimensions), but I did notice it getting pretty damn hot when I was running my system. It says it can handle -40c to +85c. I hope it won't blow

        Where did you find the electrical specs on this?

          The specs I have for T6 are actually for a different transformer made by a different company, but all the specifications are the same.
          The companies website is www.rencousa.com
          the part number is RL-5533
          BTW, you can also get free samples from them if coilcraft won't send you one...

            5v has nothing to do with T6 on Sprossy's supply.If you use more current on -12v,you will get less on 12v.

              I meant -5volts, and isn't the transformer only rated at 630ma???
              So, as I said before, how can you draw 1.3amps???

                1.3A is what the National design program produced and I had no evidence to disprove it. Coilcraft did not display the current rating of their transformer.

                Very little current is used by the -12V and -5V. With the flyback design, what is not used on the -12V winding can be used by the 12V winding (limit is core saturation). If no current is use by -12V winding, 1.26A (0.63x2)is available on the 12V winding. The windings have low enough resistance to not expell much power (0.19W @ 1.3A).

                    hey sproggy buddy then how come im getting 3.3amps on the 12vdc rail ...
                    and im getting 5.3 and 5.3 on the 5 and 3.3 vdc rails

                    so i guess the meter is working fine....??

                    Then how come 3.3amps on the +12vdc rail all i have changed in your design is the SA28A diode to some equivalant one... ???

                      How come my car will go 100 miles an hour when the speedometer only goes to 80?

                      Or why can I get 16 gallons in my 15 gallon gas tank? strange..

                          Guys belive me im equally suprised .. as you are ...... i have changed five meters to check this and they all show me the same ?

                          Im really confussed here how ???? i know its not possible but then its showing me???

                          Well i shall remove some photos and post it here so you guys can see it !

                            I have a better idea, just stick your meters where the sun don't shine, and go away, there is no way that it is possible, so, don't even attempt to try to convince us...

                              Hey skinny im not trying to convince anybody for anything .. im surprised .. myself !!

                              Just yesterday i checked it again and it shows me the same...??? im confused myself

                              i know technically its not possible .. but then ....??????/ HOW COME!!!!!!

                              PSU in my car shows me 1.68 amps and a new one is showing me 3.3amps

                              Can it be that the chips i got from National has a higher amp value or the T6 has a higher amp value ... ?????
