Can a US market H2D be run on 220V?

Bambu Lab H2D

To conclude, I asked support about the eventual availability of the 200V~240V model in Canada on a 2 year horizon. Here’s the answer:

Hi there,

Thank you for providing valuable feedback and suggestions about our product.

We are sorry that in near future we may not make the 220V (240V compatible) version of the H2D to be available for purchase in Canada.

We will relay your feedback to the relevant team for further improvement of our product and service.

Thank you for your understanding and support.

Best regards,
MakerWorld

If it is something you care about, please tell them.

Bad news on the 240V conversion, but I do appreciate that Bambu gave a specific technical answer. Someone asked an engineer and got an answer. That is unlikely to happen when the respondent is executing a script in an Indian call center.

The 220V system could also use lower ampacity wiring. It probably doesn’t, but could.

While the 230V may not be for sale in Canada, I’m waiting to hear final confirmation if I can switch mine over. They sold me the 230V AC board, after all.

Bed heaters are simple power resistors connected to mains, so at 240V the current is about twice than at 120.
240V printers beds heat faster and consume more power.

People who know only a little should refrain from posting nonsense. Doubling the voltage quadruples the power dissipation. P = V^2/R.

Thank you for the heads up! Corrected!
I wanted to mind the current, not the power.
I really appreciate your kind answer to my post.

The current does double. But, P = I^2 *R, so doubling the current quadruples the power. Being sloppy with terms on a forum just confuses people. In the real world, it starts a fire.

Wow!
I really feel guilty now.
Thank you again.

Quick note here regarding swapping over to 230v, the response I got from support:

"Please still buy the Chamber Heater Unit (For 220V Printer) and heatbed (For 220V). Only the AC board is not enough. "

Dunno how much those parts are yet, but I think I’ll be sticking with 120V operation. Warmup time isn’t an issue, the only remaining issue is running a new circuit and then finding a beast of a UPS in 120VAC.

So that’s not too big a difference on the production line to divert all planned US printers to Europe

Reading the details regarding this have me disappointed. Support is telling me my H2D which has yet to be shipped (Canada) will be capable of running 240V This unit was advertised as being capable of running on 240v and now I’m in limbo wondering if my I can use my 3kVA 240v UPS or if I will have to order something else. What a ■■■■ show.

Yea the H2D has cost me a bit more because it’s 120V instead of 230V. This is so far the only thing that bothers me about the machine.

At time of writing: the only reasonable UPS option I’ve found, costs as much as my P1S Combo.

Fing stupid really.
