STATUS

Recommended

An additional inrush current limit is recommended for some system applications that require multiple systems on a single AC circuit. AC line inrush current shall not exceed 30 A peak for one-quarter of the AC cycle, after which, the input current should be no more than the specified maximum input current from Table 3.

5.8AC Line Transient Specification

STATUS

Recommended

AC line transient conditions shall be defined as “sag” and “surge” conditions. Sag conditions (also referred to as “brownout” conditions) will be defined as the AC line voltage dropping below nominal voltage. Surge will be defined as the AC line voltage rising above nominal voltage.

The power supply shall meet the requirements under the following AC line sag and surge conditions.

STATUS

Recommended

The power supply shall meet the EN61000-4-5 directive and any additional requirements in IEC1000-4-5:1995 and the Level 3 requirements for surge-withstand capability, with the following conditions and exceptions:

These input transients must not cause any out-of-regulation conditions, such as overshoot and undershoot, nor must it cause any nuisance trips of any of the power supply protection circuits.

The surge-withstand test must not produce damage to the power supply.

The supply must meet surge-withstand test conditions under maximum and minimum DC-output load conditions.
