Hello group, we are looking into purchasing a programmable DC electronic load tester for evaluating SMPS. The mainframe unit with one module will provide app. 1200W of loading. Features include constant current and constant resistance modes. Agency claims include CE Class A. How is this type of equipment tested for emissions on the input side? Having never used such a device, I am curious to know if we should be specifying a particular noise figure or parameter in our search. Intuitively, it seems to me there would be some small amount of unwanted noise generated by the excitation of the representative loading components. Wouldn't thermally generated noise be worth considering, or is this negligible? Maybe the output noise of most SMPS swamps out typical electronic load noise?
I welcome any recommendations and comments. Chet Summers Pelco email: [email protected] This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
