Acceptance Testing

Electrical acceptance testing of space power supplies tends to be more comprehensive than for other types of power supplies. Often, “connector savers” are used to protect the electrical integrity of the flight connectors. To preserve the high level of cleanliness, the space power supply may be tested while enclosed in a protective barrier.

In addition to the electrical tests, environmental tests may be performed on an acceptance basis. These include acceptance vibration tests (AVT) and thermal/ vacuum tests.

The acceptance data package is assembled and reviewed prior to shipping the space power supply. This includes travelers for all assemblies and hybrid DC/DC converters, LAT results, DPA results, etc.
