Use a buck/boost transformer in buck mode, either way, a 1.5kva transformer is probably worth more than the cooker!
The transformer I'm looking at is made in Japan, input 110-130V, output 100V, 1500W. I'm assuming this would be 15A?I agree with Max.
A 15A transformer would be sufficient, but any transformer you can buy to do that will likely well exceed the cost of buying a new 120Vac cooker.
How much would a new one cost?
I will not forget to use the transformer as the rice cooker would be my only 100V appliance...Speaking from experience.
Maybe not today, but soon, you will find yourself plugging the cooker into 120 and it will die.
I moved to Asia with a bunch of 120V appliances thinking that I would "just use a transformer" - but one by one - all the appliances got killed, it's just too easy to forget.
You can leave the cooker plugged into the transformer as the cooker takes no power when off, and the transformer takes very little idle power when plugged in.What do I need to know regarding safety? I don't plan on keeping the rice cooker or the transformer plugged in for long periods of time, only when being used, which is probably once a day.
Yes, quite safe, assuming the circuit has a proper circuit breaker at the mains panel.I just need to know if it's "considered safe" to do this.
As KISS noted, one way to prevent that would be to replace the device plug and transformer socket with one that won't plug into the 120V outlet, such as a 240V or 120V-20A types, or one of the European types.Maybe not today, but soon, you will find yourself plugging the cooker into 120 and it will die.
The Japanese made transformer I'm looking at states it is 100V, 1500W. I don't really see any other information about it other than:Yes, quite safe, assuming the circuit has a proper circuit breaker at the mains panel.
The transformer I'm looking at is "only" ~10 pounds. Would it be safe to keep the transformer on a plastic surface? I assume it wouldn't get that hot, right?if it's not too difficult put the transformer near the breaker box and run a 100V feed to the kitchen with the appropriate plug.
That transformer will be heavy. You would be better doing 240 to 100V. See https://acupwr.com/
I would not necessarily use that transformer mounted elsewhere.
Right.an induction heat cooker is not an inductive load right?
Since I assume the cooker is only on for a relatively short time, I don't see that the transformer would get very hot.Would it be safe to keep the transformer on a plastic surface? I assume it wouldn't get that hot, right?
Could you elaborate? The transformer I'm looking at doesn't have a grounding port and neither does the rice cooker - both are type A plugs.You will also need to re-reference the earth ground conductor to one side of the secondary to replicate the grounded neutral.
You can make either secondary terminal a neutral.
You will then have two conductors at this terminal, one a neutral conductor, the other the ground.
I have no clue as it's made for the Japanese domestic market...If the cooker has a two pin plug then it means it is ungrounded, and does not require the earthed neutral, in that case, but does it conform to N.A. non grounded appliance standards?
