110V ,60HZ on 220V ,50HZ Supply

One way is to change the electrical equipment for that which is 110VAC/60Hz compatible. How did the phone call with the equipment supplier go on that topic?

What - like an electric blanket?

Your forgetting the healthcare professional's Hippocratic oath "do no harm".

Well at least this medical equipment is not for directly treating a patient...

A sick human being incapable of leaving on their own will one day be lying on these beds. The environment around this bed will contain a host of fluids along with flammable and oxidizing gasses that can make an explosive gas. People will die on these beds. A large amount of tedious engineering has gone into making sure the cause of the death is not anything from the design of these beds. You will not get appropriate engineering guidance from any engineering forum on how to modify these beds.

Contact the bed manufacturer. If they do not offer a conversion method, ask if you can purchase a documentation package on the motors and controllers in these beds. Depending on what this documentation package says, your conversion could be as simple as just changing the line cord to match your power distribution outlets. You could also need every motor, controller and wire changed by a certified individual.

Use one leg of the 220 and run the beds at 60 Hz. Simple. Won't hurt anything.

Don't understand? Hire an electrician.

Since you probably aren't troubled by codes, laws or oaths, we have no useful information about your location, don't worry about them.

OT? The whole thread should be trashed!

People with no knowledge of electricity asking about things that can hurt innocent people is BS.

These foreign renegades are a menace to other people. They should be banned!!!

This seems to be "People buying medical equipment from the wrong part of the world" week.

I didn't get the memo...

What is the brilliant idea of, buy now, check the most basic specification later idea? Even the least knowleadgeable sales person on both end should check on the 110V 60Hz vs. 220V 50 Hz labeling.

Once the equipment arrives, it likely gets refused by the inspector for not having the appropriate Medical Equipment Standards Approval label.

The price premium for "domestic" equipment is not for nothing.

Does the black market have guarantees on what they sell?

Hey - be a little kinder please - it can happen to trained engineers too. Here at this location where we design and build industrial process skids, in the past month I have had to switch out 4 motors bought for the wrong voltage for the intended power supply the equipment was to be run on. Three were 575V for a 480V factory and one was a single phase 110V motor for a three phase VFD in my control package. It just happens sometimes.

Well, it shouldn't happen if you have competent people.

When a competent person makes such a mistake, they find a solution without asking the help of strangers.

The OP stated, that he has Patient beds..., as in multiple. Translation: existing or budding importer.

Did not even bother, to try one with an 110 / 220 transformer + perusing the manual. Nor did he try the same on an existing 220V circuit.

What does he want here? To perform the actual work too?

Should we arrange for a local Medical Equipment License too?!?

Maybe getting involved with the import duties too?

What else?

Simply curious, how far any of you is willing to go. Any reply with Yes, No, No.... will be appreciated.

My firm stop is right here.

these beds are donations for a hospital, so we in need to make these beds useful for this small hospital,

thanks for your attentions.

Well, this simple sentence added to the original question would have put a different light on the affair, would'nt it?

In any case, good luck with it.
