AC input nom. 3AC 480V
Mains arrangement TN-, TT- or IT-Mains. Consult factory if one phase is grounded.
AC input range min. 3x 432-528Vac fully regulated output (±2%), Pout > 48W
min. 3x 360-552Vac

permanently allowed,
see Fig. 5-1 for output voltage regulation
max. 3x 565Vac Absolute maximum input voltage with no
damage to the power supply. Output
might be off at this level.
Input frequency nom. 50 – 60Hz ±6%
Turn-on voltage typ. 3x 390Vac see Fig. 5-2
Shut-down voltage typ. 3x 355Vac see Fig. 5-2
Input current nom. 1.4A at 20A, symmetrical input, see Fig. 5-4
Power factor **) typ. 0.93 at 20A, symmetrical input, see Fig. 5-5
Turn-on overshoot typ. 1000mV see Fig. 5-3
Start-up delay ***) typ. 350ms over the entire load range, see Fig. 5-3
Rise time typ. 40ms 0mF, 20A, see Fig. 5-3
typ. 70ms 20mF, 20A, 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 buffer module
1606-XLSBUFFER48 as an accessory when longer mains interruptions need to be bridged (see section 24).
Input Voltage Range Fig. 5-1 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 57.2V
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.
