ABB DSQC661 3HAC 026253-001 Product Overview The ABB 3HAC026253-001 DSQC661 is a dependable power supply module for ABB IRC5 robot controllers. It makes sure that DC power is delivered steadily in industrial automation systems. This single-phase device features a convection-cooled design and can handle a wide range of input voltages, making it useful for robotics, machine control, and process automation. The DSQC661 is made for ABB robot systems like the IRB series. It gives off a steady 24 VDC output with an efficiency of up to 90%, making it perfect for powering control units, drives, and peripherals in tough production settings. It has strong protection against overvoltage, overload, and short circuits, which keeps downtime to a minimum in 24/7 operations. It fits perfectly into IRC5 Compact panels because it is small and has no fan. It may be used all over the world because it works with all voltages. ABB DSQC661 Technical Specifications Specification Details Input Voltage 90-264 VAC / 180-290 VAC (50-60 Hz, 10A); wide range for global use Output Voltage 24 VDC stable Output Current/Power 10A / 240W Efficiency Up to 90% Cooling Convection-cooled (fanless for quiet, reliable operation) Operating Temperature -20°C to 70°C Dimensions (HxWxD) 235 x 104 x 178 mm Weight 2.46 kg ABB DSQC661 Key Functions: Stable DC Conversion: Converts 90-264 VAC input to reliable 24 VDC @ 10A (240W) output for ABB IRC5 robot controllers and drives. Wide Voltage Tolerance: Handles global power fluctuations without interruption, ensuring continuous robot operation in variable grid conditions. Fault Protection: Built-in safeguards against overvoltage, overload, and short-circuits prevent damage and enable quick recovery. Fanless Cooling: Convection-based thermal management reduces noise, dust ingress, and maintenance for 24/7 industrial environments. Panel Integration: Seamless mounting and wiring compatibility with IRC5 Compact systems for streamlined robotics power distribution. Usage Instructions: Check that the input voltage matches the site’s supply (90-264 VAC). Connect the AC cable to the terminals, making sure to follow the IRC5 handbook for adequate grounding. Mount firmly in the IRC5 controller panel (for example, the position for DSQC661); use screws to hold it in place without blocking airflow. Connect the 24 VDC output to the robot drives or computer unit (for example, the XP0 connector). Use a multimeter to test it before turning it on. Check the state of the LEDs; if there is no output, utilize IRC5 diagnostics to find the problem. Check the fuses F6 and the transformer strapping. Applications and Benefits Great for ABB IRB robot cells used in automotive welding, assembly, material handling, and CNC integration, where consistent power keeps everything running smoothly and saves money. Some benefits include that it saves energy because it is 90% efficient, has a low MTTR because to protections, and can be used for marine and industrial modifications all over the world. For comprehensive IRC5 power distribution in industries with a lot of uptime, use DSQC662.
