Rise time typ. 40ms 0mF, 40A, see
Fig. 5-3

*) A minimum voltage of 3x408Vac is required to turn the power supply on.
**) The power factor is the ratio of the true (or real ) power to the apparent power in an AC circuit.
***) The start-up delay for mains voltage interruptions up to 350ms is close to zero. In such cases, the power supply will
immediately generate the output voltage once the mains voltage interruption is over. Do not use the 1606-XLSBUFFER24
buer module as an accessory when longer mains interruptions need to be bridged (see section 23).

Output voltage vs. input voltage and input current
Changes of the input voltage will be fully
regulated within certain limits. The
output voltage will only start to change
proportionally to the input voltage with
extreme under or over-voltages. The
yellow LED reports an input voltage
problem if exceeded by a window of
±15%. The maximum increase of the
output voltage is limited to the 29.9V
OVP level. This level will be kept
regulated for 2s before the power supply
will shut down and re ports “Shut-down”
by the red LED.
