Does anyone know of any problems with the grounding of the secondary on the TDK Lambda power supply DLP75-24-1/E DLP75-24-1/E and DLP120-24-1/E DLP120-24-1/E The primary voltage is 208 VAC and secondary 24VDC one used to supple the CPU the other for I/O

Cliff,

From looking at the TDK DLP Installation manual, I see nothing that would make me believe that there would be a problem tying the grounds together on the two supplies. The only connection that they do not permit is paralleling two supplies (+ to + and - to -).

Here is a link to this manual: https://uk.tdk-lambda.com/KB/DLP-Installation-Manual.pdf

Good luck,

Gene
