Power Req

Power Req

RE: Power Req

Europe used to be a mixture of 220 and 240V and applying ±10% gives you the range quoted on the lamp. I think the UK was the only 240V country in Europe and our voltage standard in the pre-Eurocracy days was 240V ±6% so I'm not sure where you would actually go to find 240V +10%.

If this is stage lighting then the chances are it is designed to survive on generator power too, hence the wide tolerance.

RE: Power Req

That projector is essentially an electronic device.  Hence it has a power factor corrected electronic switching supply.  That supply functions correctly in that voltage range so that  is what they label it as.

If you supply it anything in that range you're good to go.  That even means if you have some coat hanger and paper clips wiring scheme that sags all over the place as more lights are turned on or off, the unit will still function to specs.

Most all electronic supply driven devices now list the functional operating range instead of more precise country limited voltages.

RE: Power Req

In the US and Canada, the common voltages in your usage range are 208 Volts for three phase and 240 Volts for single phase. In some areas there is also 240 Volts three phase.
Your lamp should function on all of the above.
In the US and Canada 277 volts is a common industrial voltage. (Phase to neutral on a 480 Volt wye system) I would NOT use your lamp on 277 Volts without a bucking auto transformer to drop the voltage a little.
