QS40.244 24V, 40A, SINGLE PHASE INPUT POWER SUPPLY AC 200-240V Input Width only 125mm, Weight only 1.8kg 94.6% Full Load and Excellent Partial Load Efficiencies 50% BonusPower®, 1440W for up to 4s 110A High Peak Current for 25ms for Easy Fuse Tripping Safe HiccupPLUS Overload Mode Active PFC (Power Factor Correction) Negligible Low Input Inrush Current Surge Full Power Between -25°C and +60°C Current Sharing Feature for Parallel Use Internal Data Logging for Troubleshooting Included. DC-OK Relay Contact Shut-down Input 3 Year Warranty GENERAL DESCRIPTION SHORT-FORM DATA 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 a synchronous rectification and other technological designs. Output voltage Adjustment range Output current 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.
