The particularly outstanding features of the QS40.481 DIN rail power supply from the Dimension series are its extremely high efficiency and compact design, achieved through synchronous rectification, a bridge-less PFC circuit, and other unique development details. A large power reserve of 150% and built-in oversized output capacitors support the startup of high-demand consumers such as DC motors or capacitive loads. In many cases, this allows for the use of a device from a lower power class, saving both space and money. The high immunity to transients and overvoltages, as well as low electromagnetic emissions, make it suitable for use in almost any environment. The integrated input fuse and the inrush current of nearly zero simplify installation and usage. Diagnostics are facilitated by the DC-OK relay, a green DC-OK LED, and a red overload LED. Thanks to a comprehensive international approval package for a variety of applications, this device is suitable for nearly any application.
