10.2.2Dynamic Loading

The output voltages shall remain within limits specified for the step loading and capacitive loading specified in the table below. The load transient repetition rate shall be tested between 50Hz and 5kHz at duty cycles ranging from 10%-90%. The load transient repetition rate is only a test specification. The step load may occur anywhere within the MIN load to the MAX load conditions.

Notes

1)Step loads on each 12V output may happen simultaneously.

2)For Load Range 2 (light system loading), the tested step load size should be 60% of those listed.
