Hi I am working with a system which works on approximately 5kW. The voltage output of the system may go maximum upto 60-70V and hence the corresponding current somewhere around 75-80A. I have 10 such systems which I want to read one by one continuously for long periods of time. I am trying to design the best appropriate automated system for this and is looking for best hardware that would be appropriate for this purpose. On searching for some options, I found that an Attenuator SCC-A10 may be used for getting the voltage down by a factor of 10. But I am confused whether the high current will pose a problem and also how to measure this high current. I need to measure the voltage and current simultaneously. Please suggest what would be the best appropriate hardware system for the same(preferably PCI or USB) Hoping for an early reply. Thanks and Regards Reena Sharma Learning Made Easy

I will be really grateful, if you could suggest me with some of the hardware modules appropriate for my application and the way i can use them to the best. Thanks a lot Reena I could make some suggestions but do not have the time to completely understand your needs and the forums are not the best solution. Your Local NI representitive actully gets paid to do that kind of thing. a google search suggested LME was in Pasadena. Zack Collins would be the rep to contact
