3.2.5.6
AC Inrush
The peak inrush current must not damage the PSU, or the input fuse must not blow under any
conditions of load, temperature, and input voltage, including repeated, rapid cycling of the power
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 maximum specification (I 2·
t). This must be
demonstrated through measurements of the critical component specifications.
3.2.5.7
AC Line Leakage Current
The maximum leakage current to ground for each power supply shall be 3.5mA when tested at
240VAC.
3.2.5.8
AC Line Transient Specification
The AC line transient conditions are defined as sag and surge conditions. Sag conditions are
also commonly
referred to as “brownout”. Sag conditions are
defined as the conditions when the
AC line voltage drops below nominal voltage. Surge conditions are defined as the 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.
