110V to 24V Transformer
(1/3) > >>
Izzy:
Hello, I'm working on converting an electric wheelchair to a trailer moving dolly and the batteries in this thing are dead.

Instead of paying hundreds for new batterles can I just use a 110V to 24V transformer?
Does it have to be 24 AC or 24 DC.

Can I use another type of power supply that puts out 24 volts?

Thanks for your input!!
BravoV:
The transformer you mentioned is mains connected, is this what you want that the wheelchair is constantly plugged at the electricity wall outlet ?

A.k.a. your wheelchair is wired, not good for mobility.
Izzy:
Yes, I will want it plugged in!! Not concerned with having an extension cord run behind it!
Also makes it a lot more compact!!!

You need not a transformer but 24V SMPS (switch mode power supply). Transformer outputs AC but you need DC. Not to say even without rectifier, transformer will be larger, heavier and more expensive.
Zero999:
You certainly need DC, not AC. Fortunately 110VAC to 24V DC converters are widely available and aren't expensive.

How many Amps does the motor draw? If you don't know, look at the nameplate on the motor and search the Internet for the part number, if it doesn't say.

If it gives the power but not current, then it can be calculated using Ohm's law.

You need a power supply which can deliver more current than the motor will use.
