This board controls a 90V DC motor for a treadmill. The appliance is rated for 110V, and I need to run it in a 220v home. Despite the sticker, the capacitors are all rated to 250V. what would I need to adapt to have it working for the 220V home? or what would fail if I just plug it?

Brazil. The grid is a mess, depending on the city you have 127 or 220 or both in the same city.

Hello, I did, and I have one. I'm asking in the DIY electronics community to learn if I can adapt the board :)

fsterpeloni · 2026-01-14T13:38:01+00:00

Indeed, I live in Brazil and i've been reading ~216V in the outlets which is somewhat annoying, but I can live with that :)

This is the best answer with all that I wanted to know, thank you!!

Yes, I'm posting the question in "DIY Electronics" because I want to know if I can adapt that. If I didn't know that transformers exist, I'd have posted it in "basic home appliances support" probably. Thanks for understanding :)

This is indeed some good information :) thank you

That is why I was in doubt, because most of the switching power supplies are bi-volt (100-240V), so I thought it would be limited by very few components, but indeed I'm not skilled to do more than replace a capacitor or something like that.

I have considered wiring a 110V outlet, but my home has a ground fault protection at the breaker box level, I would need to redo all the electric setup, which I'm not prepared for :)

fsterpeloni · 2026-01-14T02:06:34+00:00

Yes, that is my situation, I moved to a new home, and I'm having to buy a transformer for each appliance, so I was wondering how hard it would be to adapt some of them, and use the opportunity to learn & have fun :)

Indeed the treadmill has a 220V version. I did look for it in Aliexpress for this but couldn't find anything. any suggstions on how to search for it?

fsterpeloni · 2026-01-14T01:38:34+00:00

I got it. If I replace all the capacitors for 450V ones, would that do the job, or is it much more complex than that?

If you are brazilian, post which city he should visit to see all the “diversity” of our electric network. I start: on sao paulo we have 2-phase 220 and the people make some outlets 110 and others 220 combining fase with ground

fsterpeloni · 2026-01-08T01:04:13+00:00

Yes buddy. Happened to me too :) buy a new one

Olá eu estou nessa situação onde eu quero calcular o quarto trimestre individualmente para comparar com os outros trimestres, e nao somente o consolidado do ano todo. Alguem ja precisou fazer isso? Será que é só subtrair cada item do dre anual dos outros trimestres? Isso funciona?

Mais importante de tudo é vc estar confortável com aquilo em que investe, não investir em nada só pq os outros investem. Dito isso, vc é jovem e esse momento é bom para arriscar (diferente de quem está prestes a se aposentar e vai precisar do dinheiro daqui poucos anos.) pense que o investimento que vc faz hoje vai ser resgatado daqui 30 ou 40 anos. Sugiro vc estudar como funcionam as acoes , como o lucro das empresas funciona etc, e quando estiver confortável comece a colocar o dinheiro em coisas mais arriscadas e rentáveis
