Inquiry: Measuring High DC Voltage and Current with ADE7880

In theory disabling the high pass filter the ADE7880 will meter DC. The issue is performance. There are dc offsets from the ADC that vary with temperature and there is no way to compensate for this. when measuring AC the high pass filter removes this dc offset. I do not recommend using the ADE7880 for DC measurement. What sensors are you planning to use to measure current? For DC measurement the ADE9113 with ADE9178 or ADE9113 and a micro controller might be a better option. Possibly the ADEMA124 or ADMA127 with a micro 

Note the working voltage of the ade9113 you may need the ADE9103 or ADE9102 and separate isolation.

We would like to clarify that our measurement focus is DC only, and we intend to move away from AC measurement in this application.

We prefer to keep our current schematic if the accuracy and reliability are acceptable after configuration changes; otherwise, we will plan to migrate to the recommended solution.

We are considering using Hall-effect current sensors (or a DC-capable alternative) for measuring the ~2000 A current at ~470 V. Do you have any evaluation board or reference design based on the ADE9113 (or one of the other recommended devices) that supports high-voltage DC measurement, which we could use as a development reference?

Additionally, do you have a recommended IC for measuring both AC and DC in a single solution (for future flexibility)?

We would appreciate any available documentation, board part numbers, or support you can provide for proceeding with a suitable solution.

We are planning to use Hall-effect current sensors (or another DC-capable sensor) to measure approximately 2000 A at 470 V DC. Do you have any evaluation boards, reference designs, or application notes that demonstrate high-voltage DC measurement with your recommended metering ICs that we could use as a development reference?
