Wide-Range Input
All QUINT POWER, MINI POWER and STEP POWER power supply units are equipped
with a wide-range input. Therefore, all one-phase power supply units can be operated on
line voltages from 85 to 264 V AC and all three-phase power supply units on line voltages
from 320 to 575 V AC. These voltage ranges cover the most important supply networks
worldwide.
Compared to devices with a fixed voltage input, devices with wide-range input have the
following advantages:
–
–
–
Systems may be tested at any production location and may be operated anywhere in
the world without erroneous switching over of the input voltage.
Wide-range inputs ensure reliable functioning of the power supply units even in the
event of high voltage fluctuations caused by instable supply networks.
Using power supply units with wide-range inputs reduces storage and logistics
because for one performance class only one devices is required, independent of the
input voltage.
When selecting a power supply unit it must be considered that the term "wide-range input"
is not always used clearly. Automatic switching over of the input voltage ranges ("Auto
Range"), for example, is incorrectly used for wide range.
Auto-range devices detect the applied input voltage and switch over internally between the
different input voltage ranges. Operation between these defined input ranges, e.g., in the
even of voltage fluctuations, is not reliable.
