摘要:
A power supply unit according to a preferred embodiment of the invention is self testing. The power supply unit is enabled to function with no external loads applied, and includes a visual indicator of whether or not one or more voltage outputs of the power supply unit is within tolerance. To benefit from the self-test feature, a user in the field may simply unplug the power supply unit from all loads, plug the unit into an A/C source, and observe the visual indicator. If the visual indicator is lit, then the user may reasonably assume that the power supply unit is functioning correctly. But if the visual indicator is not lit, then the user may reasonably assume that the power supply unit is faulty.
摘要:
An electrostatic precipitator that removes zinc whiskers from cooling air provided to cool components in an electronics enclosure. The electrostatic precipitator comprises an ionizer configured to apply a charge to zinc whiskers suspended in the cooling air. The electrostatic precipitator also comprises a collector that collects charged zinc whiskers from the contaminated cooling air to generate uncontaminated cooling air for cooling the components of the electronics enclosure. The electrostatic precipitator is configured to be disposed in the cooling air flow path upstream of the components such that the cooling air travels through the electrostatic precipitator prior to impinging on the components.
