AC Line Fast Transient (EFT) Specification
The power supply meets the EN 61000-4-5 directive and any additional requirements in
IEC1000-4-5:1995 and the Level 3 requirements for surge-withstand capability, with the
following conditions and exception:
IEC1000-4-5:1995 and the Level 3 requirements for surge-withstand capability, with the
following conditions and exception:
These input transients do not cause any out-of-regulation conditions, such as overshoot
and undershoot, nor do they cause any nuisance trips of any of the power supply
protection circuits
