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.

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

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...

I'm a mech engineer so this stuff is really confusing me. How is 115V the same as 120V. I know about the 10% rule, but why is the nominal voltage not always used in discussions, if 120V is nominal why are some people calling it 115V? Can someone list the types of voltages that are possible in...

Hello, I've got a device that connects to a computer via a short 3m USB cable. I'd like to be able to this with a 100 feet distance. The converters I've seen require a RJ type connector at the PC end, I need a db9. ALso I'm on a $400 budget :) Hopefully that will be neough. Thanks

Good Day, Is it electrically correct (in terms of wiring standards) to use the shield wire in a cable as Ground(-).

I have a client who would like a connection to my PC's Card (a pci card). so that I could write files to the PI historian databse. Can a PCI card produce a format that a PI database can accept?

I would like to use a 28 awg shielded cable over a distance of 50 meters. Will it work? Or is it better to use 22 or 24 awg. This is for trasmission of digital and 4-20mA analog signals.

I am looking for a converter that will convert a PCI 2.2 card to a PCI 2.1, so that I can plug it into a PCI 2.1 compatible slot. Does such a thing exist? This is what each looks like: PCI 2.2 : http://www.alloy.com.au/images/ALLOY-1440SC_500x500pix_LoRes.jpg PCI 2.1...

Any Books, Self paced tutorials, guides availabe on the DeltaV program? (For those who don't know what DeltaV is, its a DCS programming tool).

I have PC anywhere and use that to re-start a PC remotely, but sometimes the PC gets frozen and I have no way to restart the PC. I am searching for another way to re-start the PC (a soft not a hard-restart). Is there any way this can be accomplished? Many Thanks

Hi there, Which enginerring software/program looks good on a resume. I am planning to invest some of my time & money into an instrumentation type of software such as Labview maybe?? of which I know the very basics. What appeals to employers and what is considered valuable to have?

HI all, Looking for an 'Air condionted' clime controlled Box. To keep electronics and equipment at contant temperature. Where to find one? Approx. Price ranges? Thanks for the tips!

Hi, Im looking for a compact PC for continous online measurment. Any recomendations?

I have a switching power supply that I am using and as soon as I turn it on, there is a very wierd squeking noise (very annoying), is this attributed to the frequency of the switching? Is there anything I can do to eliminate this very loud audible noise?
