With respect to this requirement is a Declaration of Conformity from the Power Supply manufacturer (for such supplies as you normally find in standard desk top work stations) sufficient for compliance with this requirement ? Is it necessary to test every model in every application and if so why ?
It appears this requirement is such, that a component approval would cover the requirement on such standard designs, provided the unit is tested at various load conditions. Example: minimum load, mid-point of load curve, and at maximum rated load. If the DOC from the vendor is adequate, then the testing and related cost can be held to a minimum. If not the power supply will need to be tested for every user and multiple testing of the same product will result. Comment please. Leo Heiland Compliance Engineer SCI Systems Inc. 205-882-4743
