The outstanding features of the DIN-rail power supply QS40.481 of the DIMENSION series are the extremely high degree of efficiency and compact design by synchronous, a bridge free PFC-switching and other unique development details can be achieved. A large power reserve of 150% and built-in large output capacitors support the run-heavy loads such as DC motors or capacitive loads. In many cases it enables the use of a device from a lower power class, which saves space and money. The high immunity to transients and surges as well as low electromagnetic interference emissions make the use in almost any environment possible. The built-in input fuse, as well as the inrush current of almost zero simplify installation and use. The diagnosis is through the DC-OK relay, a green DC-OK-LED and the red overload LED easier. Thanks to an extensive international approval package for a variety of applications, this device is suitable for almost any application.This text is machine translated.
