    Transformer

    Anyone have a source for a transformer like this? 120 v ac primary 12 v dc secondary .5 amp foot mount 2.0" bolt pattern.

    Thanks

      Digikey, Mouser, Newark ... not sure you'll find one with 2.0" bolt pattern but plenty of transformers like that.

      12v x 0.5A is about 6w, a 15-20VA transformer will be good replacement. for example see digikey list: http://www.digikey.com/short/38m0ht

      For this one http://www.digikey.com/product-detai...544-ND/3986349

      Connect secondaries in parallel and you have 12v up to 1A, put it on one side and use plastic electric cable ties or some other method to attach it to pcb.

      These two have 2.81" between the holes:

      1. http://www.digikey.com/product-detai...1041-ND/952911
      2. http://www.digikey.com/product-detai...949-ND/5032163

        I found it on a pool and spa supply parts site. Used to power pool and spa controllers as well as low voltage lights in them. who woulda thought?

          RadioShack sells 12V Transformers, they are expensive, but convenient if you need it quick. They sell a 1.2A 12V one for approx 10-15$ It's labeled 6.3-0-6.3 because it produces 12.6V with the two outer wires. They are not very large.

            Original Xbox 1.0 PSU: Foxlink FTPS-0002 Rev. B. — 12 V low, 5 V high — transformer?
            by ohren
            Hello!

            I'm looking at an original Xbox PSU: Foxlink ftps-0002 rev. B. The 12 V output is too low, and the 5 V output is too (?) high. Unfortunately I don't have an oscilloscope but only a DMM for diagnosis.

            Measured voltages with no load:

            After rectifier diodes
            12V: 6.17 V
            5V: 5.67 V

            Secondary transformer pins AC measurement (really don't know if this says anything)
            12V: 2-2.5 V
            5V: 1.04 V


            I also have another (working) Xbox psu from Delta. The same measures there, in order, being: 10.79,...

            Is it possible for transformer substitution?
            by mikey5791
            Hi all,
            Got this local made DC power supply (12/14V) given free as the transformer has melted. There is no marking or indication to identify what type or rating of transformer used.
            Fyi,. I had a busted autogate mainboard with transformer with marking 13-0-13 . Is this the 13v dc type transformer?
            My questions are
            1. How do i test to see if the transformer is in good working condition?
            2. Can this transformer (marking 13-0-13) be used to replace the melted transformer on the DC power supply?
            Hope you guys understand what i was asking. My intention is...

            3PHASE STEP-DOWN Transformer in Check
            by dennis_elx33
            Hello All,

            i would like to post an interesting topic regarding 3-phase stepdown transformer which we suspect to cause an overcurrent (138A) which resulted to power tripped off of the HV power supply (80KV output).


            Problem statement: Power tripped Off

            Initial Problem: Found 2 IGBT and 2 rectifier diodes shorted (burnt).

            Action Done:
            1) Replaced the faulty parts with good spare.
            2) Measured impedance of the 3phase input lines and found that L2 to L3 has 23.3ohm while other pairs are 51Kohm. This pins will...
