Robobrew in US

[Cire10]

I know they were previous post about using the Robo brew. But no one specifically said they are using it in the United States.

Australia is 240V and 50 Hz. I understand I could run it on 220 V but the hertz is what worrying me .

Is anyone using this on our 110 V 60 Hz electrical supply?

you mean 240v 60hz power in the us right? it wont run on 120v..

The US has 110V 60Hz. You can make it 220V 60Hz. But AUS is 240 V 50 Hz.

ok semantics here... You would still be powering the robobrew with 2 120v lines which when combines make 240v ac at 60 hz right? (residential wiring usually shows 235-240v with a meter, commercial wiring would show 208v) Your not not attempting to run this off 120v alone which was what I was asking.... Because it wont work for sure on 120v regardless of HZ... The controller is the only thing that may have an issue with 60hz.

I asked Robobrew if it would run on 60hz on their facebook page a couple days ago and have not yet seen a response. You could always ask the manufacturer, I seen them selling these on alibaba.

I was born and grew up in the British Caribbean which used 240V 50Hz also. We used a lot of appliances from the US which was rated at 120V 60Hz but we used a step down transformer that dropped our voltage to 120V 50hz. The only issue was had was with timers and clocks. Most timers and clocks use the frequency of the mains powers to keep time since the frequency is constant. It will probably work just fine but the timing features may be a bit off.

Thanks for the info. I have several emails into the manufacture waiting to hear. They sell several components on their website that are rated at 50–60 Hz. So I'm hoping they made the robobrew out of those components

I'm not really surprised, if your talking about the australian company that sells them they dont make it... They were being sold on alibaba and aliexpress direct for a while until the company seemed to work out a deal to be the exclusive seller it seems because they are gone now. In any case these are from china not Australia... they are just being marketed by a company there.

Greetings! How can you make the conversion from 110 to 220? I've done some searches but have found nothing yet...any tips or information will be appreciated! Cheers,

In the United States, typical household current is supplied to your house in 2 phases. Both are 120v (sometimes called 110v; it's really the same thing, just called by slightly different voltages). The two phases are 180 degrees out of phase with each other.

AC current cycles between +120V and -120V 60 times per second (in the US). When phase A is at +120V, phase B is at -120V. If connect a circuit between phase A and phase B's hot wires, you get a voltage difference of 240V.

Here's the Wikipedia explanation: https://en.wikipedia.org/wiki/Split-phase_electric_power Figure 1 shows how it works.

the Robobrew sold in NA is 110V
here is a link to a local shop in Canada

I currently purchased an AU RoboBrew 65L. The circuit board is marked 240V AC. The 35L boards are marked 120V AC. I read on there web site that the 240V version 65L can be wired 120V using the neutral wire in US and Canada. The only problem is all the elements can't be used at the same time, it would trip the breaker. In AU they have 240V potential from Line 1 to Neutral at 50Hz. In US and Canada we have 120V from each phase to Neutral and 240V phase to phase. I believe the robobrew can be hooked up using the two 120V lines with no neutral. This would be feeding the board with 240V phase to phase at 60Hz. I have not wired mine like this yet....but will verify if it works! I'm going to wire it this way tonight.

Available in the US here for one. 110V

I bought a 65L Brewzilla from AU. The board had a checkmark on 240V. I wired it 120 using neutral and it worked fine but I was only able to use the two smaller elements. I then wired it 240V 60Hz using no neutral it is working fine. I switched the cord to an US style 240V 15A cord. I would assume they use the same board in the AU model and US. So if any body buys one from AU just change the end of the cord to a standard 15A 240V end and wire it with no neutral.
