Four series of line transient tests were performed on the EP-34 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 a resistive load. An
LED was used to monitor the presence of output voltage and to detect output
interruptions. The secondary return was hard wired to the safety ground at the surge
generator. This is a worst-case test condition for common mode surge and ring wave
testing, and the test results reflect this. If surge tests are conducted without this ground
connection, the common mode surge/ring wave withstand is higher. Test for each series
was terminated upon non-destructive interruption of output voltage, arcing, or non-
recoverable interruption of output voltage.
recoverable interruption of output voltage requiring supply repair or recycling of input AC
voltage.
