Three-phase Power Supplies

In order to meet demands for complete, comprehensive system solutions, power supplies for mounting rail installation are available in the B&R product line. This extensive spectrum ranges from 2.1 A single-phase up to three-phase power supplies which can 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 mount allows fast mounting and demounting. Wiring is essentially performed in seconds thanks to the the cage clamp terminals 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.

All other power supplies (starting with PS105) feature a metal housing, which protects the internal electronics from small parts (such as screws) using a fine ventilation grid. Sophisticated mounting mechanics enable user-friendly installation on the mounting rail. Simply hang the unit, snap it on and your finished. Even the 40 A unit sits as though it were screwed in.
