POWER SUPPLY AC 100-240V Wide-range Input QS40.241-A1 ATEX Approved with Conformal Coating Width only 125mm, Weight only 1.9kg 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. 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 this Dimension QS40.241 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. 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 nominal 24 - 28V 40 – 34.3A continuous 60 – 51.5A short term (4s) Output power 960W continuous 1440W short term (4s) Output ripple < 100mVpp 20Hz to 20MHz Input voltage AC 100-240V -15%/+10% Mains frequency 50-60Hz ±6% AC Input current 8.6 / 4.5A at 120 / 230Vac Power factor 0.99 / 0.99 at 120 / 230Vac AC Inrush current typ. 16 / 9A peak at 120 / 230Vac Efficiency 93.6 / 94.6% at 120 / 230Vac Losses 65.6 / 54.8W at 120 / 230Vac Temperature range -25°C to +70°C operational Derating 24W/°C +60 to +70°C between 85-90Vac see chapter 18 Hold-up time typ. 27 / 27ms at 120 / 230Vac Dimensions 125x124x127mm WxHxD ORDER NUMBERS 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.

4. INPUT INRUSH CURRENT The power supply is equipped with an active inrush current limitation circuit, which limits the input inrush current after turn-on to a negligible low value. The input current is usually smaller than the steady state input current. Inrush energy Inrush delay Inrush current*) over entire temperature range; mains interruptions > 1s over entire temperature range; mains interruptions > 1s over entire temperature range; mains interruptions > 1s The charging current into EMI suppression capacitors is disregarded in the first microseconds after switch-on.
