14 AC Surge and 100 kHz Ring Wave Immunity
Four series of line transient tests were performed on the EP13 to determine the level of
immunity attainable for the basic board. Testing was performed using a Keytek EMC Pro
surge generator. The input voltage for the supply under test was 230 VAC, and the
supply was loaded to the maximum continuous output power using resistive loads on
each output. An LED was used to monitor the presence of output voltage and to detect
output interruptions. Test for each series was terminated upon non-destructive
interruption of output voltage, arcing, or non-recoverable interruption of output voltage. A
test failure was defined as a non-recoverable interruption of output voltage requiring
supply repair or recycling of input AC voltage.
