Greetings from Michigan.
I have an application where we want to monitor voltage and current coming off the output side of the AC motor drive. We would like to monitor one leg of the three phase. We are using a Reliance Electric GV3000 drive. Circuit is 480, 3-phase.
For voltage, I have a Phoenix Contact transducer module (MCR-VAC-UI-O-DC) wired up and monitoring one of the output legs. That appears to be working fine.
For current, the frequency on the output is going to change anywhere from 3-100 Hz. Or at least that is what is reading on the drive display when I change the speed of the motor. I don't have any way of verifying frequency on the output side of the drive (My Fluke doesn't have the capability). Point being, the simple AC Current transducer that I originally thought would work, will not.
Is there something out there that will work for this? The current needs to be monitored in the PLC.
Thank you
