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.
