Post Subject: DSET GroundingPosted by anthony on: 8/7/2016

Hi Romy,

I am designing the power supply chassis for the DSET at the moment and hope that you can remember some things about how you managed the grounding.

All power supply components up to but not including the filter caps for each power supply will be held in the PS Chassis with the remainder held in the Amp Chassis. I assume that this is how you managed things. My question is basically whether you amalgamated the DC ground inside the PS or whether you waited until the Amp Chassis to join to common ground? If the grounds for the various power supplies are joined in the PS Chassis then we would get away with fewer ground wires in the power cables between the boxes but this is not an issue for me, there are plenty of wires in my cables and connectors.

I suppose this question then extends to the Bias PS, the centre tap for the filament transformers and the electrostatic screens for the various transformers...do you ground those in the PS or Amp Chassis? According to the schematic, the Bias PS will be attached to common ground in the Amp Chassis.

Thanks for your help,

Anthony
