5.10 AC Line Fast Transient Specification

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.
