    Need help getting an isolation transformer

    Can anyone recommend an isolation transformer or a possible link to one that will work with my techtronix 465B scope i just got..

    I don't have a clue to what would be the correct one so any advice would be great.Also would like to get it here in the uk as it would probably cost to much to ship otherwise.

    Thanks in advance.

      What is the mains input rating on the scope?
      My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

          the scopes psu probably is isolating,
          it's the stuff your testing you need to isolate.
          also good to have an earth-leakage breaker.

              That post is a few months old.

              It looks like sam67 bought one off ebay going by his post in another thread.

                  isolation transformer from two 240/12, wiring?
                  by harp
                  When is talk about making isolation transformer on poor-man way, always I see schematic 240/12-12/240.
                  So, I wonder, is this wiring from my attachment it work, bringing some good feature or it is bad idea and why?...

                  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...
