Design and Environmental Specifications
8.2.2

Dynamic 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 Δ step load may occur anywhere within the MIN load to the MAX load
conditions.
Output
+3.3V
+5V
12V
+5VSB
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.
8.2.3

AC Line Transient Specification

AC line transient conditions are defined as "sag" and "surge" conditions. "Sag" conditions are
also commonly referred to as "brownout"; these conditions are defined as the AC line voltage
dropping below nominal voltage conditions. "Surge" is defined to refer to conditions when the
AC line voltage rises above nominal voltage.
The power supply shall meet the requirements under the following AC line sag and surge
conditions.
Duration Sag
Continuous 10%
0 to 1 AC 95%
cycle
> 1 AC cycle >30%
