Thread 105812354

Are these reliable for continuous use? I recently moved to Europe and need a step-down transformer for my fridge which only supports up to 115 volts. the European voltage standard is fucking retarded (230 volts), i can’t use most of my appliances here because they either won’t work or risk overloading and blow up

Don't bring your US trash to the developed world if it can't handle a real electrical grid.
But seriously, get a new fride. I most likely uses too much power for an adapter like this

>moves across the globe
>hauls the fucking fridge with him
anon, you have the opportunity to acquire healthy habits. don't waste it.
leave the burger lifestyle behind, preferably alongside your american fridge that can fit a small herd.

>>105812354 (OP)
Why the fuck would you take your 110V appliances with you? You probably paid more to get them over there than it would've cost you to just get something locally

>>105812485
>>105812476
>>105812393
yeah, i know it wasn’t the smartest move but it’s done now, i can’t afford to replace my appliances right now. So I was wondering if picrel could help me still use the ones i already have.

>>105812354 (OP)
Look up the max wattage your fridge uses. This adapter looks pretty strong and it might be fine if your appliance is the only one plugged into it. Also look up the fine print on the adapter and see if they specifically forbid large appliances. The pictures on the product are all small, so I have to wonder.

>>105812599
>The pictures on the product are all small
it says is compatible with all American appliances rated at 110-120V, 0-1600W, the only problem i can see is the one in OP doesn’t convert frequency from 50Hz (EU) to 60Hz (US), but I’m not sure how much that actually matters since most American appliances support both 50Hz and 60Hz anyway.

Who the fuck can afford to move a fridge instead of buying one?

>most of my appliances

Seriously why are Americans like this?

>>105812354 (OP)
>>105812393
Fridges do not use very much power even when they're defrosting.

>>105812679
Anything with a motor in it probably only runs at 60 Hz. I think.

>>105813505
some motors tolerate the frequency difference others don’t, if the fridge is 60Hz only there's no guarantee it’ll work safely or properly long-term, even with a step-down transformer may help with voltage, but not frequency, and often not enough for compressor-type devices

>>105812775
cry about it

>>105812354 (OP)
Yes they probably are reliable
When I was a kid my parents moved from a 110v to a 220v region and took all appliances with us, so we had transformers all over the house. Everything always worked fine.

It was 110v 60hz to 220v 60hz though. Yuros use this dumb-ass retarded 50hz frequency. You have to make sure the transformer can deal with that, especially for appliances that use motors/compressors.

>>105812354 (OP)
What the fuck? Did you move your fucking fridge to Europe? Do Eurotrash houses not come with appliances?

>>105812354 (OP)
Did you literally take your fucking fridge from America to Europe?

>>105813863
yes so what? i paid a lot but at least i have all my things with me

It's cheaper to just buy a new fridge then importing an old fridge from America.

>>105813307
Not on average, but inrush currents can be very high when the motor starts.

Also the 50/60Hz thing is a real problem for transformers and motors. At the wrong frequency the magnetic material can saturate and overheat.

>>105812354 (OP)
>the European voltage standard is fucking retarded (230 volts)
230V is based. 110V is weak shit.

>>105815686
>Also the 50/60Hz thing is a real problem for transformers
is it? there are transformers that can convert both voltage and frequency, but the frequency shouldn't matter that much anyway

>>105815739
It does.
Frequency affects transformer frequency.

The only reason modern power supplies can use tiny ass transformers is because they increase the frequency.

>>105815749
*transformer efficiency

>>105815714
>110V is weak shit
who cares? you don't need more than 110V for anything, it should have become the standard everywhere so i don't have to buy a new fridge every god damn time i switch countries

>>105813647
I'm not the guy with the fridge shaped paperweight

>>105815778
reminder that americans boil water in microwaves and need a special plug for their clothes dryer

everyone laughs at you

>>105815749
well designed motors and transformers can tolerate a frequency change if voltage is also adjusted but it’s not automatically a problem unless the device is frequency sensitive

>>105815686
>At the wrong frequency the magnetic material can saturate and overheat.
true but at higher frequencies saturation is less likely at the same voltage

>>105815814
ok i didn't know we were the retarded ones, im still not sure why the frequency is different, is it 60Hz better or worse?

>>105815096
Please leave us alone, we don't want you. You are a retard.

>>105815739
>there are transformers that can convert both voltage and frequency

There is no such thing as a transformer that can convert frequency. You need active electronics to do that aka a switching power supply.

>>105815932
Does not make a difference really

>>105815897
>At the wrong frequency the magnetic material can saturate and overheat.

>true but at higher frequencies saturation is less likely at the same voltage

Yes, but if you go from 60 to 50Hz (move from US to Europe) the frequency gets lower.

>>105815814
wait, Japan is 50hz? how?
they used the NTSC tv standard right?
how did they get 60 frames on the CRT from 50hz power?

>>105812354 (OP)
i get what you did, packing all shit so you dont need to bother getting news shit or whatever, not the most economical shit, but something is just easier that way
people on /diy/ probably know better
but a 240 to 120 v transformer is something that many old houses have, and many old shit was 120v too, shouldnt be that difficult to get one
now the 50hz vs 60hz... most shit shouldn't be that different, some motors will run on a different speed, not a big deal usually, but you could never be sure
i would oversize the transformers just in case.

also, you could do solar and batteries and a 120v 60hz circuit for your mutt stuff, or even just a battery charger and an inverter if you cannot have solar, so you have the extra advantage that you can charge when electricity is cheap

>>105815800
we don't think about you at all

>>105815997
Half of the country is 50hz and the other half is 60hz. When they were getting their electrical grid started, one city got their equipment from Germany and a different one got theirs from America, and they expanded outward until they met up in the middle (and all hell broke loose presumably)
So they just make everything compatible with both frequencies

>>105816068
There's a transformer station and a couple high voltage DC lines at the border near Tokyo. Apparently this is one of the reasons why japan took off in electronics. Because they suddenly had to get really good at building switching power supplies.

>>105816046
you're thinking about us right now

why are americans so stupid?

>>105816090
>>105816068
wow, I learned something today.

>>105816028
yes, voltage is easy to fix with a transformer, and a lot of electronics are fine with 50/60Hz. But for motors and timing-sensitive stuff, frequency does matter. oversizing transformers won't solve that

>you could do solar and batteries and a 120v 60hz circuit for your mutt stuff
Requires capital investment in inverter + charger + wiring

>>105815800
>Americans: boil water in a microwave in 90 seconds.
>Europeans: spend 5 minutes on a kettle and 2 days air-drying clothes

>>105816157
>Europeans don't have clothes dryers on their 240v electrical grid because they don't have a special 240v plug

>>105816145
>Requires capital investment in inverter + charger + wiring
a charger + inverter i doubt is more expensive that the equivalent frequency and voltage converter, bc they are kinda the same. given how i guess those are more niche, i would expect them to be way more expensive for a given wattage than the "solar" solution

>>105816157
A kettle is much faster than a microwave.

>>105816188
The actual funny thing is that they have the washing machine in their kitchen and do all of the dishes by hand because they don't have dishwashers in their houses

it just occurred to me that all the whining about EV's draining electrical grids and needing extremely heavy duty wiring probably all come from americans with their aluminium foil wiring running at 110v

>>105815943
>switching power supply
i just want to power my fridge god dammit, why is it so complicated? how much does this cost? how do i use it?

>inb4: just replace your fridge
NO

>>105816220
Just replace your fridge

>>105812354 (OP)

American home appliances are decades behind in technology. Do not carry these across the pond, you fat fucking shart.

>>105816251
i've already did, there's no way back now, i can’t even sell this stuff here cause theoretically it's all junk now, i need a solution for the appliances that are 50Hz only

>>105816220
its only about the fridge? maybe you could talk to a technician to swap the compressor. that way you also get a newer part, those go bad with time

>>105816277
sorry i meant *60hz

>>105816277
Cut your losses and trash it.
Don't fall for the sunk cost fallacy.

>>105816279
>you could talk to a technician to swap the compressor.
that would cost more than the fridge itself, no way

>>105816218
Our electrical grid is actually 240v when it's running through the power lines. It gets split into two phases of 120 at the transformer before it goes into the house. To get 240 you just bridge the two sides together in the electrical panel

>>105816295
yeah and thats what they cry about, having to get a 'expensive and high tech' 240v socket

>>105816295
Our grid (Europe) is actually three-phase 400V. You just only use one phase on most plugs. One phase is 230V. No transformers needed!

>>105816332
>230 + 230 + 230 = 400

>>105816277
>>105816220
You will fry any appliance with a motor if you use an adapter, no matter how big or advanced it is. Even fucking hair dryers die when you take them to countries with different voltages and plug them into """"proper"""" transformers.

>>105816366
>what is RMS voltage

>>105812354 (OP)
>110v
America is so hilariously backwater.

>>105816366
You have to divide by sqrt(3), you can't just add the RMS voltages of the three phases together.

>>105816370
you're a lying sack of shit, most of these have overload protection, we're not in 2009 anymore retard

>>105816366
It's √3 * 230 = 400.
You can not just add them together because they are shifted by 120° in time.

>>105816290
which fridge is it?
is a dumb one?
bc if its a dumb one you shouldnt need to care about the hz, a transformer would be enough
anon give us more details

>>105816430
What? It's the complete opposite.
Smart electronics don't give a shit about the frequency since they rectify to DC anyway.
It's the dumb AC motor that cares about frequency.

>>105812393
fpbp
>>105812354 (OP)
You're retarded for thinking 230V is retarded. Most of the world uses 220-240V. 110-120V is only used in north-middle America and Japan. 230V can deliver twice as much power for the same current (and wire gsugeu) compared to 115V.
You're better off replacing your appliances if you intend on staying for any significant amount of time. Type E/F plugs are also much safer than Nema.

>>105816444
anon electronics of appliances that are made for countries that uses motors of a given frequency voltage are not always universal... bc they cannot be sold in other parts of the world...
>>105816512
anon that doesnt show us if there is electronics or anything that we could think may not be adapted

>>105816444
>>105816614
yes it's an AC motor, it uses an R600a compressor so it may overheat if it's pluged in a 50Hz transformer, the compressor is the weak link and no electronics will protect it from overheating due to saturation.

>>105816747
electronics can absolutely protect a motor against overload

>>105816760
lol no, also PTC starters are thermally timed and their characteristics assume 60Hz operation so it's always an overheating risk

>>105816760
Yes, by shutting it down. That still doesn't make it work. It will just not make it kill itself.

>>105815997
It is possible to make TV sets that work with both. Most European CRTs work with 60hz signals too.

>>105816277
is there a plate on the back of the fridge that lists the power requirements along with model number etc.? If that says 50/60hz then you should be fine with just a transformer.

>>105817184
I've posted it here >>105816512
115V~60Hz, im fucked right?

>>105817310
sorry didn't see it.
yeah, you're probably fucked. It may work on 50hz but probably not well or for very long.

>>105812354 (OP)
fuck off we're full

>>105816068
I remember when someone tried to doxx a Japanese vtuber by asking what the AC frequency is where she lives.

Burn it all down. What britbongs have done for you?

>Having more wattage is retarded
Ok but actually tell me why 230v is bad.
You know some appliances in the US need high voltage hook-ups too right?
