HI everyone would a 24v heated bed work on a Ramps 1.4 a with a Arduino Mega 2560.
Thanks

Only with a separate PSU and a DC-DC SSR or an external MOSfet to switch it on/off

Could the I mod the Ramps 1.4 to 24v and will the arduino board handle that voltage?

yes and no.

read RAMPS_24v carefully.

I used a 24V 450W bed on a printer and would never do that again. Go with line power switched by an SSR. The SSR won't need a heat sink and you won't have to worry about burning up your PCB or MOSFETs with the high current that a 24V bed will need. Add an electrical fuse and a TCO for safety.
