All components used in high-voltage power supplies
should be screened per Section
of this guideline. Screening procedures for high-voltage components are the responsibility of the individual power supply manufacturer. The screening program must include, but not be limited to:
(1) Corona test
(2) Thermal cycling
(3) High-voltage burn-in.
All subassemblies shipped as spares must receive the same total ESS as those subassemblies procured as a part of a complete final assembly.
The final assembly of high-voltage power supplies
should be subjected to ESS defined in Section 4.6
, modified as follows:
Following random vibration and 100% parametric test and prior to temperature cycling, an altitude test should be conducted, with continuous monitoring as follows:
a. 4 hours at altitude and minimum system operating temperature
b. 4 hours at altitude and maximum operating temperature
c. 100% parametric testing per the customer's Acceptance Test Procedure.
