IC or converter for 3phase power to 0- 10V AC power |

Hi friends,
does anybody know tha IC or device which is used for converting incoming 3 phase voltage and current to 0-10V range output?
for example each line voltage R,Y,B individually should give their output in the range 0-10V.
pls reply... _________________ uma

Talk about vague....
You need to start by working out what you actually want to 'do' with the values.
Several different possible devices may be involved depending on the answer.
Current transformers. Hall effect sensors. Transformers. Resistive dividers. Power meter IC's. etc. etc..
What may get closest to what you want, depends on what you actually want.
In your title, you say '10v AC', but in here you say '0-10v'. Very different.
Three small transformers, and three current transformers will give you six 0-10v AC outputs. |

As Mr T says.. it depend on application.. however Google led me to a Maxim product(78M6631) that is a complete SoC(System on Chip) for about $10.
frankly due to the potentially LETHAL ability of 240VAC, I'd buy a premade 'evaluation' module.
Another option is to buy 3 'Kill-o-watt' units and interface them to a PIC(fairly simple).
In the good old days, I'd do as Mr. T suggests...3 voltage transformers, 3 current transformers, 6 burden resistors,few diodes,caps and 'play on the bench'. Any PIC with 6 ADC inputs will work for the project. Just be very,very careful...while 240 might not kill you directly,it'll toss you off your stool,spill your coffee..generally make a mess of your day.
