Integrated protection mechanisms
When the PSSu E F PS1(-T) or PSSu E F PS2(-T)(-R) is used to supply the system, the
module supply is buffered for 20 ms if the supply voltage is interrupted.
The module has the following protection mechanisms:
}
Common second shutdown route, tested regularly
}
Cyclical output tests
