Product Description
The most outstanding features of this Dimension QS40.481 DIN-rail power supply are the extremely high efficiency and the small size, which are achieved by a synchronous rectification, a bridgeless PFC circuit and additional unique design details. Large power reserves of 150% and built-in large sized output capacitors support the starting of heavy loads such as DC motors or capacitive loads. In many cases this allows the use of a unit from a lower wattage class which saves space and money. High immunity to transients and power surges as well as low electromagnetic emissions makes usage in nearly every environment possible. The integrated input fuse as well as the near zero input inrush current make installation and usage simple. Diagnostics are easy due to the DC-OK relay, a green DC-OK LED and the red overload LED. A large international approval package for a variety of applications makes this unit suitable for nearly every application.
