Patronics CA1000JH. Two outlets, a switch, a fuse and a large transformer. That's it. Bought it for $8 at a resale shop.
Is This an Isolation Transformer ?

Re: Is This an Isolation Transformer ?
No, the bad part is that, they put the AC power input fuse on the Neutral (White wire) instead of the Hot wire. You should verify that Hot and Neutral wires are properly wired up.Never stop learning

Re: Is This an Isolation Transformer ?
its a buck/boost transformer. 220v for australian junk and 100v for old radios.
(thats what i use mine for at least)Things I've fixed: anything from semis to crappy Chinese $2 radios, and now an IoT Dildo....

You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.
Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

Re: Is This an Isolation Transformer ?
It is an multi-tap autotransformer. You can use you AC voltmeter and the measure the AC voltage between the Neutral and Ground, Hot and Ground to see what you get. In US, the Neutral is tied to ground at the circuit breaker panel, so Neutral to Ground should show 0V (it may show perfect 0V if there is load in the same circuit using that same Neutral wire.Last edited by budm; 02-07-2014, 09:44 PM.Never stop learning

Re: Is This an Isolation Transformer ?
Yep autotransformer. There is no isolation - you can see that one wire of the input (120V) is connected to both outputs - that's not isolation.
It's how to get 220V for European devices in the USA. I was wondering about Patronics, is that a Canadian company? They don't seem to be well listed on Google.
I have only a Sabir 250VA autotransformer to get 220V from 120V or 120V from 220V. This one is also an autotransformer (no isolation) and was made in France as far as I can tell... Unfortunately it definitely was made in the EU as the input plug is a dual pin and thus can't really use it without an adaptor or modification...Comment

by harpWhen 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?... -
by ohrenHello!
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,... -
by mikey5791Hi 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... -
by dennis_elx33Hello 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... -
