    Transformer Help

    Hi. I just pulled this transformer from this Xtreme Power Conversion(maybe APC knockoff?) UPS and I have no clue how this transformer is wired up. I have attached some photos below for reference. Googling the number on the top turns up nothing.

    P.S: Sorry if this is in the wrong section; it's the best one I could find.

    Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

      Re: Transformer Help

      You could use an ohm meter . Highest ohms is probly the primary.
      P.s. I do see 94 144 v

          That must be an inverter transformer...

          MAYBE

              Re: Transformer Help

              The side with two red wires and one black wire are connected to the POWER MOSFETs for driving the inverter transformer from batteries source when it is in UPS mode.
              The side with white (Neutral), the Black, and brown wires are for LINE, the UPS probably select which wire to use when UPS is in AC mode to maintain 120vAC output by tap switching. the white connector with RED/BLACK wire may be for power supply for running the board.
              If you can upload the pictures of the UPS with all the wires connected then we can verify.

                  The BM3060VA name may indicate it's a 30v AC 60VA transformer

                  There may be multiple taps from 94v to 144v so that if there's too low mains voltage or too high mains voltage, by changing taps it's possible to keep the voltage close to 30v AC.
                  Or, the other way around.

                      I'm actually stripping out the UPS, but I can do that. Will do shortly.

                          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...
