ABB DSQC604 3HAC12928-1 Power Supply Module

Product Description

Key Specs

• Input Specifications:
  • Voltage: 3-phase 400V AC ±10% (50/60Hz); single-phase 230V AC ±10% (optional, via wiring configuration).
  • Input current: 3.5A (3-phase, full load); 7.5A (single-phase, full load).
• Output Specifications:
  • Main output: 24V DC, 20A (regulated, ripple ≤50mV); overcurrent protection (25A, self-resetting).
  • Auxiliary output: 5V DC, 2A (for logic circuits); 15V DC, 1A (for sensor power).
• Isolation & Protection:
  • Input-output isolation: 2.5kV AC (1min); output-output isolation: 1kV AC (1min).
  • Protection features: Overvoltage (30V DC max for 24V output), short-circuit, and thermal overload protection.
• Mechanical & Environmental:
  • Dimensions (W×H×D): 140mm×210mm×180mm; weight ~3.2kg (fits IRC5 controller rack).
  • Env: 0°C~+40°C, 5%-95% RH (non-condensing); IP20 (rack-mounted inside IRC5 cabinet).
  • Compatibility: Exclusive to ABB IRC5 standard/compact robot controllers; replaces DSQC601 legacy modules.

Core Functions

1. Stable Power Conversion: Converts 3-phase/ single-phase AC input to regulated 24V/5V/15V DC outputs, supplying consistent power to IRC5 controller components (e.g., CPU, drive amplifiers, safety relays).
2. Multi-Output Isolation: Isolates different DC outputs to prevent cross-interference—e.g., 24V motor control power does not affect 5V logic circuit stability.
3. Fault Protection: Triggers overcurrent/overvoltage shutdown for short circuits (e.g., 24V output shorted to ground) or voltage spikes, protecting robot electronics from damage.
4. Status Monitoring: Built-in LED indicators (AC Input ON, 24V Output OK, 5V Output OK, Fault) for quick troubleshooting—e.g., red Fault LED lights for thermal overload.

Core Advantages

1. Robot-Specific Compatibility: Optimized for IRC5 controllers—no external wiring modifications needed; ensures seamless integration with robot safety and drive systems.
2. High Reliability: Regulated outputs (ripple ≤50mV) prevent voltage fluctuations from affecting robot motion precision (e.g., consistent positioning in automotive welding).
3. Redundant Protection: Multi-layer safeguards (thermal, short-circuit, overvoltage) reduce unplanned downtime in critical robotic processes.
4. Legacy Replacement: Direct drop-in replacement for DSQC601 modules in older IRC5 controllers, extending the service life of existing robot systems.

Applications

1. Automotive Robotic Assembly: Powers IRC5 controllers for welding robots, ensuring stable 24V DC for drive motors and 5V DC for position sensor logic—maintaining precise weld joint alignment.
2. Material Handling Robots: Supplies power to IRC5-based palletizing robots, with 24V output driving conveyor integration circuits and 15V powering vision system sensors.
3. Electronics Manufacturing: Supports IRC5 controllers for pick-and-place robots, where low-ripple 24V DC ensures accurate component placement (±0.1mm precision).
4. Food & Beverage Robotics: Powers IRC5 controllers for packaging robots—isolated outputs prevent electrical interference from wet environments (e.g., washdown areas) affecting control circuits.

Precautions

1. Input Configuration: Confirm input wiring (3-phase vs. single-phase) matches the robot’s power supply—incorrect wiring (e.g., single-phase into 3-phase input) damages the module.
2. Load Limits: Do not exceed 20A for 24V output (e.g., avoid adding external 24V devices to the module); overloading triggers fault shutdown.
3. Installation: Mount only in IRC5 controller racks (reserved slot); ensure cabinet ventilation (ambient temp ≤40°C)—overheating causes thermal overload.
4. Replacement: Use only ABB-genuine modules—counterfeit modules may lack protection features, leading to IRC5 controller damage.
5. Troubleshooting: Before replacing, reset the module (power cycle IRC5 controller) for temporary faults (e.g., momentary voltage spike); if Fault LED persists, check for shorted outputs.
6. Grounding: Ensure proper cabinet grounding (≤1Ω) to prevent EMC interference from affecting output stability—critical for robot motion accuracy.
