18. Power supplies
In order to meet demands for complete, comprehensive system solutions, power supplies are
available in the B&R product line for mounting rail installation. This extensive spectrum ranges
from single-phase power supplies that supply 2.1 A up to three-phase power supplies that supply
40 A. All switching power supplies can manage a wide range of AC and DC input voltages. This
input ranges from 100 to 240 VAC or 400 to 500 VAC and from 85 to 375 VDC. Devices are
protected against short circuit, overload, and open circuit, which allows them to be operated
without functional limitations or derating even when overloads between 15% and 25% occur.
Two mini power supplies (PS102 and PS104) in robust plastic housing are available in the lower
performance range. A well-designed cooling concept allows several different mounting
orientations. The functional DIN rail allows fast mounting and removal. Wiring is essentially
performed in seconds thanks to the spring clamps being used. The compact design, easy
mounting and several different mounting orientations make the two smallest power supplies in
this product line components that can be used practically anywhere.
