The ABB DSQC661 3HAC026253-001 power module is a power module designed by ABB for its robot control systems, particularly the IRB robot family. It is responsible for providing a stable power supply, supporting the operation of the servo drive system and the robot control system. This power module is mainly used in the field of industrial automation, especially in robot applications requiring high precision and high reliability.

Here are the details of the product:

1. Product model and series
Model: DSQC661
Product Number: 3HAC026253-001
Brand: ABB
Application: Robot power module to provide power support for power conversion and distribution in ABB robot control systems.
2. Main functions and effects
Power conversion: The power module receives and converts from an external power supply (AC power supply) to the DC power supply (DC voltage) required by the robot system to provide stable power to the robot controller and servo system.
Servo motor drive: The DSQC661 module provides the drive voltage and control signal for the servo motor, ensuring the high precision and stability of the robot movement.
Power distribution and regulation: Through power regulation and control, the module provides different voltages and currents for different robot components (such as controllers, sensors, actuators, etc.) to ensure the normal operation of each component.
3. Electrical parameters
Input voltage: usually AC 380V-480V, suitable for standard industrial power supplies.
Output voltage: The module converts the input AC to direct current, usually output 24V DC or 48V DC, depending on the needs of the control system.
Input current: The current ranges from 5A to 30A, depending on the power required.
Output power: The output power of the power module is usually in the range of 1kW to 5kW, and the specific output power varies according to the specific configuration.
Operating frequency: Suitable for 50/60 Hz power system.
4. Control and communication functions
Control mode: The power module adopts servo control technology to ensure stable power output and achieve accurate voltage and current control.
Feedback systems: Support the exchange of feedback signals with other components in the ABB control system, such as servo drives and robot controllers, to optimize overall system performance.
Communication protocols: Common industrial communication protocols such as RobotWare, Ethernet/IP, Modbus, Profibus, etc., ensure seamless communication and data exchange with ABB robot controllers such as IRC5.
5. Protection function
Overload protection: When the system load is too large, the module automatically limits the output current or shuts down to protect the system from damage.
Overvoltage/undervoltage protection: When the input or output voltage exceeds the predetermined range, the power module will automatically shut down to prevent damage.
Overheat protection: Built-in temperature sensor monitors the module temperature to prevent power damage caused by overheat.
Short circuit protection: When a short circuit is detected, the power module will quickly disconnect the power supply to avoid device damage.
Overcurrent protection: When the current exceeds the maximum safe limit, the power module automatically cuts off the current.
