DC voltage RMS measurement

[jan_opsteyn]

We are looking for dc voltage measurement of the 35V dc RMS voltage measured with 0.1ms / sample.

Input = 525V, this will be adjust with thyristof bridge for  the correct AC voltage 10kHz switching frequency.

We want to measure the dc voltage 0-35v on the place where the red circle is placed below. This we need to read out in pme through modbus. Or with 0-20mA/ 0-10V

Did somebody already measured with this sample time? I don 't find a power meter with this capabilities.

Hello,

Are you looking for DC offset from an AC signal?

It is a dc signal from 35v DC and current 16000A. The current probe is 0-10V  = 0-20000A. This we read in the pm8000 analog input.

But we want the 35Vdc measurement connected  to the pm8000 so we can calculate the energy.

Hello Jan,

The PM8000 cannot do what you are looking for for a few reasons:

a) Analog input is 30Vpeak

b) Calculations on the analog inputs are done once a second
