Hello, I would like to share a recent failure with the SDS panel.

The panel works fine for about 2 hrs and then the voltage and current have large fluctuations with loss of communication. This problem was reproduced at the base
The suspected TPSD card which is responsible for the tool power supply regulator was replaced and tested for close to 3 hrs and the issue is resolved.

What are the possibilities for TPS card failures?  We haven't seen the TPSD card failures that often.
