As the internal Playstation power supply is not universal (it can't accept both 110v and 240v), you need a a 240v > 110V converter (known as a step up voltage converter). Check the sticker on the bottom, in Australia at least it does not mention 110V compatibility, if it does on whatever region your PAL console is from then you will be fine. This is true for pretty much all consoles that have an internal power supply. Any money you saved on the playstation console will most likely be negated because depending on the quality these can cost $50 bucks right into the hundreds. Be sure for plenty of wattage headway, most sources suggest doubling the wattage at a minimum. The Playstation is 9W so this should not be a massive issue. I use the reverse of these (a step down voltage converter) for my Japanese (110V) consoles as mains power in Australia is 240V.
Also as you mentioned PAL>NTSC, the PS1 is softcoded for region, so it will output the resolution and frequency of the software in it, if the system is chipped it will play US PS1 games exactly like a US PS1 would.
Realistically, you would be far better off buying a NTSC PS1.
