Bottom preheat 220V 50Hz on 60Hz American power line?
(1/2) > >>

How you doing guys. There is this great bottom preheat made by Russian defense industry corporation, Termopro NP 10-6 Pro, when it comes to iPhone pcb repair it's the caddilac of preheaters, precise, ergonomic, super advanced, bar none the best out there. However, it is designed to work with 220 - 230 volts an 50 Hz. I'm not sure if it has switching mode PSU or linear, I asked tech support, waiting for reply, but let's assume both cases.

I know that in the US you can get 240 volts 60 Hz (btw, voltage in my outlets in Russia is 239 volts). Question is will this preheater work at 60 Hz voltage frequency?

Another related question, I bought me Aoyeu 2703+ (yea I know, but it does it's job), this station is for 220 volts and 50 Hz and it has linear PSU inside it. Can I use it in the U.S. at 60 Hz? I just don't want to sell it for a lot less money if I move, although I might out of convenience.

The heater itself will just be a resistor and won't care whether it's AC or DC, but the controller will.

Running linear or switched mode power supplies at 60Hz, rather than 50Hz is not an issue. There will be very slightly higher hysteresis losses in the transformer but the ripple on the DC side of the rectifier will be lower. It's running 60Hz equipment at 50Hz which is more troublesome.

The only issue I can think of is it might use the mains frequency as a timebase, which would result in it running a bit fast, on 60Hz vs 50Hz.

It's also possible to use an inverter to generate 50Hz from 60Hz.

I doubt they would use mains freqfor reference, this is nuclear weapon and space company we talking about, that’s why I want that preheat so badanyway. Though I will ask techs about this. Thanks you.

LOL :-DD. Where did you get this nonsense? BTW it's rated for 220-230V, 50-60Hz. No issue there.

u666sa:
Where did you get 50-60 hz??I read twice everything.

As far as what was said, because it is what used by different bearous. In repair industry it is confirmed to be king here, dudes who went jbc dropped it and went this way. There is a reason, precision, speed, and enorgonomics. I wont argue, I seen it, I want it. i want nothing else.

It goes to me nimizing return rates. I’m a simple man.
