GridTrak PMU Model A
Rev 9.7, April 2012

GridTrak PMU Model A, Rev 9.7
* Measures Frequency and Phase Angle for 60Hz and 50Hz AC signals
* Calculates the magnitude for an ideal sine wave of the signal
* Maximum sample rate = 30 to 60 samples per second, reliable rate = 10 samples per second
* GPS PPS Input
* Dual RS232 interfaces for communications with Host PC and GPS
* Uses the AC signal source as the circuit power supply
* Optional jumper to isolate the AC signal from the circuit power supply for using a separate DC power source
* Schematic, PCB Layout, and Firmware source code are Open Source available on GitHub
* IEEE C37.118-2005 output compatible with openPDC and PMU Connection Tester
