Thank you everybody, I really enjoyed reading this thread!

Digital filtering is not the only option but its the the one I am most familiar with. Did you try Google Books?

I am Looking at this Stage Lighting Lamp and not quiet sure of what to make of the power spec. Power Requirements: Standard AC power distribution from 200– 264 VAC, 50/60 HZ. The unit requires 7 to 12 A depending on the AC supply voltage. Is 200-264VAC standard in the US? Is this perhaps for...

Suppose a wire is carrying 3 phase ac current, as you increase the current, by what magnitude must the cross sectional area increase by? Is this a linear relationship? Thanks.

A link to the part from digikey or any other mfg. would be greatly appreciated! By air I mean instrumentation air, 35 psi. I'm thinking a simple tube with a mechanical contact that closes when air flows through from one direction. Here's a drawing..lol ;) ________________________...

I need help finding this part, I don't know what its called, but I can describe it: Part checks air in a line, If there is Air in the Line, Output=1 else 0. Voltage to be tied from external power supply. Would digikey or a similar supplier have something like this? THANKS

yes mate, have contacted several, no reponses

Circuit maker? http://www.circuitmaker.com/

How much would a 30kVA, 480V Primary, 120/208V Secondary THREE phase transformer weight, roughly? Thanks, ppc

Hello, How much would a transformer like this cost? Any idea where I could get something like this? Thanks. -Step down transformer going from 277/480 Volts 3 phase TO 120/208V 3 phase voltage. 30.1 kVA /nextup. -Smallest and lightest (weight) possible transformer -Able to work in an outdoors...

Just though Id add this Single-phase voltage | Three-phase voltage (rounded) 100 173 110 190 115 200 120 208 127 220 220 380 230 400 240 415 277 480 347 600

Got it! Thanks Bill!

120V/208-230V 3 phase ...what is meant by this?

OK that helps, so is 208V same as 230V?
