    Can anyone help me identify this transformer?

    I've scoured the internet with the hopes of finding a replacement for this thing, but the more I search and the less I find has me thinking that it must be a custom piece.

    If someone could shed some light on how I might be able to figure out it's specs(inductance, type of winding, etc.) that'd be a great start. I can't even seem to find one with a similar pin layout. All I know is that the relays on the board it came from are all 18V.

    As always any help would be greatly appreciated, I know someone out there can point me in the right direction!

      Re: Can anyone help me identify this transformer?

      Does it have a bridge rectifier or does it use two diodes
      And what is the cap voltages near the transformer because I
      Thinking that it might be a 15 volt transformer
      You might be able to use a 12 volts one

          When looked at again I noticed that it has three rows of pins that is a special transformer
          You might have to use two transformers if you have space

          Can you please take a picture of the board this transformer came off of

              Definitely need to see the board and how all the pins are connected.
              What is bad about it? it can be that not ALL the pins are being used.
              The more details the better.

                  Thanks for your interest guys, the problem is that the transformer shown is fine, but the transformers in two other panels are blown and need to be replaced.

                  Here's some shots of the board:

                      Are they physically burnt up or open. Some transformers have thermal fuses under the wrapping.
                      I assume no responsibility for any stupid suggestions I might post.

                          Yes sir, definitely no chance of resurrecting them!

                              Do you know what the voltage of each winding is you do
                              Do you have enough room in cabinet to use two transformers

                              If you can give us the voltages on each windings I will try find some transformer or transformers for you

                              Could you rewind the ones you have just thought

                                  The problem is you can't use a transformer in place of a flux capacitor. Do the math
                                  I assume no responsibility for any stupid suggestions I might post.

                                      Great Scott dskall, you're right!

                                      My apologies for not getting back to you guys, I tore my bicep tendon last week so I wasn't able to power up the panel to test, when I do I'll let you know the specs!

                                          Re: Can anyone help me identify this transformer?

                                          I've given up on trying to source a transformer for the time being, mainly because I was able to find an identical working one.

                                          But of course nothing can truly be that easy........the transformer works in the panel, but the second it's powered on it slowly but steadily gets warmer and warmer until it becomes dangerously hot.

                                          I suspect this is the issue that led the original transformer to its toasty demise, but the reason why is eluding me......

                                              maybe a bad cap on the output

                                                  Interesting, the only cap I can think of is the big one in the picture above, any way to check without a scope or should I just replace?

                                                                                  I'm attempting to repair the SMPS on a Levoit 600S air purifier. The transformer is likely open. It has six pins. 2 pairs on the primary side (one pair tested open) and 1pair of legs on the secondary side. Legs on the secondary side are spread wide apart (end-to-end). I've circled them in blue. Dimentons of the transformer are 22x23mm. Marking on the transformer are EE16 1.9mH-B. Fuse for the powerboard is fuse 250V 3.15A. I've been unable to find an exact match and I'm hoping for some help here to find a suitable replacment.

                                                                                  Peace

                                                                                  it's this one and i cannot identify it so i can order a new one.

                                                                                  Also it would help if someone can tell me if it could be the reason why my Imac will not start.

                                                                                  The green led is "on " on the motherboard , but when i hit " power on" nothing happens.

                                                                                  i will attach the schematics here.
