PULS QS40.244 INTRODUCTION
The most outstanding features of the DIMENSION QSeries DIN-rail power supplies are the extremely high efficiencies and the small sizes, which are achieved by synchronous rectification and other technological designs.
The QS40.244 is a device for 200-240V mains voltages. Large power reserves of 150% 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 emission, makes usage in nearly every environment possible. The integrated output power manager and input fuses, 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.
