View Full Version : Is US 110V the same as Site 110V? EddScott 28 November 2006, 17:19 Need to know for a project I'm working on. Looking at a Site 100V motor and drive system and unsure how to power it. Don't want a big site transformer to lug about if I can help it. Ta :) John@TunerUK 28 November 2006, 18:12 You can use US 120V equipment on UK 110V transformers with little ill effect. But don't forget that site transformers are 'centre tapped' to earth, so it's really like having 2 x 55 volt phases, rather than 1 x 110v phase. This makes them much safer, which is why they're used on site. Chip Sengravy 29 November 2006, 10:29 I thought US was 60+60 volts, as per UK 110 ? John@TunerUK 29 November 2006, 11:03 Well, I wasn't sure myself, so I had a good look on t'internet last night. Wikipedia say's it's the same as here, with a phase, neutral, and ground which is connected to the star point at the source. The same as the UK in all but voltage.:wonder: EddScott 29 November 2006, 17:21 So could I use a cheap 110V to 240V transformer - Say what I use to power a US Xbox 360 - to power a 110VAC motor? (25W / 8amp) Chip Sengravy 29 November 2006, 18:08 is the drive for the motor variable speed? post up details of the motor and drive. alcazar 29 November 2006, 20:49 Isn't the US on 60Hz too? Alcazar ru' 29 November 2006, 21:47 So could I use a cheap 110V to 240V transformer - Say what I use to power a US Xbox 360 - to power a 110VAC motor? (25W / 8amp) If the motor is 110V AC and 8 amp, it's lots more than 25 Watt (try around 880 Watts...), and there's no way a cheap little transformer will do I'm afraid. US is 60Hz (we're 50Hz) but that shouldn't make too much difference if you get a transformer which is meaty enough... EddScott 29 November 2006, 23:15 Cheers for the help. Am going for a 12v motor now. Ta :thumb: John@TunerUK 30 November 2006, 08:41 Isn't the US on 60Hz too? Alcazar Yes, forgot to mention that:cuckoo: |
