You are kidding right? Why exactly would someone "give" you this info?

i want to know the current rating for 5kva ups,o/p=230vac.how will u cal.don't tell VA=VXI,tell some other methods.

i would like to know the lowest price sellers ups manufactures in INDIA.

thank you

I agree with Andy.Answer is no.

"pls give me the ckt. of single phase ups with redundancy and by bass condition."

Have You Tried Google?

To such requests made in such a manner I have no problem is just using the word "NO".

dear all,

i'm not able to understand the things right now.

ok! if u r in my position what would be ur ans. and ques.

When one writes shorthand as in a request, that's just being lazy. My lazy responds…Zzzzzzzzzzz

dear all,

pls leave that query which was made on UPS!

I've designed the circuit and got the approval from the NTPC.

pls tell me how the current becomes zero in star condition.

thank you,

naveen.m

Add the voltage on the tip of each of the 3 points on the star, the resulting voltage should be zero (or close enough to it)

If you have a imbalance in your phases, then the center may not be zero, but it should.

You really are to much. You dismiss all who responded to this thread then proceed to ask another question. What planet are you from?

Mr. A to Z,

This is no way of asking. I do agree with Andy because he was able to express my feelings in a better way.

A manufacturer of a controller chip may provide an application circuit in the datasheet. If you are inquiring on the schematic of a commercial end user product you won't find it. Engineers do a lot of R&D work to bring products to market and investors/management expect the designs to stay proprietary for the sake of business. In our economy, people who work hard are rewarded. You should try it sometime.

Well said...
