Hi, in my current solution I have only a spare channel for DC value (upper channel in the figure).
Recently, requirements changed and now I need synchronization with the grid, i.e. measure voltage and use PLL (phase locked loop). What would be the easiest and simplest solution to do that and get something like in the channel below?
In voltage transducer board can I scale and add offset so I can get the unipolar input to the exiting PCB board? Are there any other solutions? I am reluctant to do any modification on the exiting PCB board as it is really compact and all SMDs. Voltage transducer board input is +/-15Vdc and the output is measured signal.
