line. Half cycle peak inrush current, peak repetitive input current, and worse case power factor
must be provided by the vendor to assist with the UPS and line conditioning, sizing, and
selection. No component will be stressed over its Max Specification (I 2·t). This must be
demonstrated through measurements of the critical component specifications.
3.1.6.7 AC Line Leakage Current
The maximum leakage current to ground for each power supply shall be 3.5mA when tested at
240VAC.
3.1.6.8 AC Line Transient Specification
AC line transient conditions shall be defined as “sag” and “surge” conditions. “Sag” conditions
are also commonly referred to as “brownout”. These conditions will be defined as the AC line
voltage dropping below nominal voltage conditions. “Surge” will be defined to refer to conditions
when the AC line voltage rises above nominal voltage.
The power supply must meet the requirements under the following AC line sag and surge
conditions.
