Re: [neonixie-l] OT: Reasonable quality step-up converter?

2018-11-04 Thread Terry S 
An inverter would convert to DC and back again to AC, thereby being able to 
convert 50 to 60 hz. This looks to be a real step up/down transformer. I'd 
plug the whole thing into an isolation transformer and then put a scope on 
the output. I can't imagine that a real transformer could have a distorted 
output unless you were over-taxing it. Then it might saturate and clip.

2018-10-24 Thread Bill van Dijk 
If you need some reasonable current, use a good sized isolation transformer 
(110 – 110) and wire the secondary to one line. If you have the polarity right, 
you will now have a 220V auto transformer (if the polarity is wrong you get 
nothing :)). Works fine for me.

Hi folks,

This is a bit off-topic, but I hope somebody can help. As some of you know I 
live in Canada, but I am originally from Germany. Most of my tools can be 
switched between 110V/220V input, so that's fine, except for my soldering 
station. It is a Weller 40W digital station that I have had for years and I do 
not want to buy a new one. The problem: it only has a 220V input.

So I was looking for a step-up converter, and I was surprised by the crappy 
quality of almost everything out there. If you look on Amazon or Ebay, there 
are a lot of types very similar to this one here:

*   
http://www.amazon.com/Instapark-ITU-500-Voltage-Converter-Transformer/dp/B07B9F87HG/

Usually around USD 50 with quite a few negative reviews (typically around 10%) 
of people saying it eventually almost burned up their house. Not interested! So 
I was trying to find something reasonable, which turned out to be a bit more 
difficult that I had originally anticipated. I found these here:

*   http://www.kriegermfg.com/products/voltage-transformers/

Do you think these are reliable? Or where else can I find something of decent 
quality? I am looking for something around 300-400W.

Many thanks and best wishes from Canada

Re: [neonixie-l] OT: Reasonable quality step-up converter?

2018-10-24 Thread gregebert 
Jens - Can you install any 220V outlets in your garage ? Typical setup in 
US/Canada is for homes to have 3 incoming wires (120V-neutral-120v). Most 
outlets are 120V, which is across the neutral line and either of the 120V 
"hot" leads. To get 240VAC, use both 'hot' leads.. At the 
meter/circuit-breaker panel you have ready access to 240VAC.

Another option, and it's ugly, is to locate 2 AC outlets that are powered 
from different 'hot' sources; that will get you double the line voltage 
across the 2 'hot' leads.

Most likely, the 60Hz mains in Canada wont impact your soldering station 
that operates on 50Hz.

I have an extra 120V / 20Amp isolation transformer (and it can 
step-up/step-down for 220V)  that I would be happy to give to you, but it's 
too heavy to ship.

  where in Canada are you  ?   I have several quite big heavy duty ones.  check for any  hamfests   ( just google that term)  in your area - often there are many available there because they were used to run CB type radios etc. It's an amateur electronics style flea market.   I am in Brampton Ont  so if you are not too far we could meet up   they are too heavy to ship.
  Thanks  Phil

   Hi folks,
   This is a bit off-topic, but I hope somebody can help. As some of you know I live in Canada, but I am originally from Germany. Most of my tools can be switched between 110V/220V input, so that's fine, except for my soldering station. It is a Weller 40W digital station that I have had for years and I do not want to buy a new one. The problem: it only has a 220V input.
   So I was looking for a step-up converter, and I was surprised by the crappy quality of almost everything out there. If you look on Amazon or Ebay, there are a lot of types very similar to this one here:
   
http://www.amazon.com/Instapark-ITU-500-Voltage-Converter-Transformer/dp/B07B9F87HG/
   
   Usually around USD 50 with quite a few negative reviews (typically around 10%) of people saying it eventually almost burned up their house. Not interested! So I was trying to find something reasonable, which turned out to be a bit more difficult that I had originally anticipated. I found these here:
   
http://www.kriegermfg.com/products/voltage-transformers/
   
   Do you think these are reliable? Or where else can I find something of decent quality? I am looking for something around 300-400W.
   Many thanks and best wishes from Canada Jens

Hi folks,
