I need an isolation transformer to do tv repair. Will this on work and can it be modified to work for TV repair on primary side?

Re: Isolation Transformer-Will this work?
Looks like it will but take note you will need a 230/240V input to output 115/120V.
If you feed it 120V you will only get 60V out.
It should support reverse operation as a step-up transformer, with 120V in on the secondary giving 240V out.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Isolation Transformer-Will this work?
If your handy with a grinder and a welder you can make your own out of a pair of microwave oven transformers. Just make sure they are identical cut the seam weld on the top of the laminated core, gently coax out the primary coil and replace the secondary coil in the other transformer, spot weld back together and wire in a cord on one side and a plug on the other. Mine was made of all recycled parts for free.Liberating magic smoke one part at a timeComment

Re: Isolation Transformer-Will this work?
I made one out of an old microwave transformer years ago, I just chopped out the secondary winding and re-wound it, I can't remember the wire size I used but it worked out to be about 1 volt per turn. The transformer does run a bit hot due to the welded laminations.
Now I use a large transformer and isolate the whole bench.Comment

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,... -
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... -
Hello, I have an "ASUS ROG Strix G713QR" laptop, and for approx. 3 months I have the following problems:
1. Laptop keyboard doesn't work
2. The backlight on the laptop keyboard doesn't work
3. The x2 side LEDs (red) on the laptop don't work
The power button works, the touchpad works, and all the USB, HDMI, Ethernet, etc. ports work.
I already tried to reinstall all the drivers and reinstall Windows. So I don't know what to try anymore that is software-related.
But I am strongly aiming that it is somehow a BIOS-related problem,... -
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... -
