QT40.241 24V, 40A, THREE PHASE INPUT POWER SUPPLY 3AC 380-480V Wide-range Input Three Input Fuses Included Width only 110mm, Weight only 1.5kg 95.3% Full Load and Excellent Partial Load Efficiencies 50% BonusPower®, 1440W for up to 4s 110A Peak Current for 25ms for Easy Fuse Tripping Active PFC (Power Factor Correction) Active Filtering of Input Transients 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. Remote Control of Output Voltage 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 A large international approval package for a variety of applications makes this unit suitable for nearly every application. DC 24V 24 - 28V 40 – 34.3A 60 – 51.5A Output power 960W 1440W Output ripple < 100mVpp Input voltage 3AC 380-480V Mains frequency 50-60Hz AC Input current 1.65 / 1.35A Power factor 0.88 / 0.90 AC Inrush current typ. 4.5A peak Efficiency 95.3 / 95.2% Losses 47.3 / 48.4W Temperature range -25°C to +70°C Derating 24W/°C Hold-up time typ. 25 / 25ms Dimensions 110x124x127mm Weight 1500g / 3.3lb ORDER NUMBERS 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, the three input fuses and 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.
