3.2.14 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 shall meet the requirements under the following AC line sag and surge
conditions.

3.2.15 Power recovery
The power supply shall recover automatically after an AC power failure. AC power failure is
defined to be any loss of AC power that exceeds the dropout criteria.
3.2.16 Voltage Interruptions
The power supply shall comply with the limits defined in EN55024: 1998/A1: 2001/A2: 2003
using the IEC 61000-4-11: Second Edition: 2004-03 test standard and performance criteria C
defined in Annex B of CISPR 24.
3.2.17 AC Line Isolation
The power supply shall meet all safety agency requirements for dielectric strength.
Transformers’ isolation between primary and secondary windings must comply with the
3000Vac (4242Vdc) dielectric strength criteria. If the working voltage between primary and
secondary dictates a higher dielectric strength test voltage the highest test voltage should be
used. In addition the insulation system must comply with reinforced insulation per safety
standard IEC 950. Separation between the primary and secondary circuits, and primary to
ground circuits, must comply with the IEC 950 spacing requirements.
3.2.18 AC Power Inlet
The AC input connector should be an IEC 320 C-14 power inlet. This inlet is rated for
10A/250 VAC.
