Technical Specifications

The ABB DSQC625 3HAC020464-001 Computer Power Supply serves as a critical component in providing stable and reliable power to computer-based control systems in industrial automation applications. Its primary function is to convert and regulate electrical power from an input source to the appropriate output voltages, typically 5V and 12V DC, which are essential for the smooth operation of connected devices and systems.

Troubleshooting & Comissioning Checklist

Isolate Main Power: Turn off and lock out the main circuit breaker of the IRC5 controller cabinet.
ESD Protection: Wear a grounded ESD wrist strap before handling internal computer module components.
Inspect Physical Seating: Confirm the DSQC 625 is firmly mounted with no loose screws or metallic debris inside the computer chassis.

Field Engineering Considerations

Harness Relief: Ensure all DC output wiring harnesses are routed cleanly without tight bends or tension on the terminal plugs to prevent fatigue-induced loose connections under industrial vibration.
Firm Seating: Ensure the unit is mechanically aligned and firmly locked into its dedicated sub-rack. Loose mounting compromises the unit's grounding plane and disrupts stable thermal dissipation.
Tooling Requirements: Swapping the module requires standard industrial hand tools defined in the ABB IRC5 Product Procedures Manual. Avoid utilizing power drivers to prevent stripping internal panel threads.

Technical FAQ

Q: What is the exact function of the DSQC625?
A:The module converts incoming voltage inside the controller cabinet into stable, low-voltage DC power. This directly energizes the main IRC5 robot controller computer, ensuring reliable data processing, logic control, and communication operations.

Q: Can I use a standard IT/Desktop PC power supply as a replacement?
A: No. The DSQC625 operates on a low-voltage DC input (10–30V DC) provided by the IRC5 cabinet's internal power distribution, whereas standard consumer PC power supplies require 110V/220V AC input. Always use the original factory part or an exact OEM matching industrial unit.

Q: Is there a regular maintenance routine required for the PSU?
A:The power supply unit itself does not have internal serviceable components. However, its lifespan is highly dependent on its operating environment. Ensure the computer unit fans are fully functional and free of dust build-up to prevent thermal stress and premature PSU failure.

Q: Do you supply brand-new, original parts or second-hand refurbished items?

A: Our stock consists of Original New items; all products undergo quality inspection to ensure they are fully functional.

Q: What guarantees are included with the shipment?
A: All items in stock are tested by engineers, packed in professional ESD packaging, and shipped via express logistics with a global delivery time of 24–48 hours.

Q: How long does global shipping take?
A: Stock items are typically dispatched within 24 hours. Shipments are sent via DHL or FedEx Express, taking approximately 3–5 days to reach Asia, 4–6 days to Europe and the Middle East, and usually arriving within a week in major industrial regions worldwide.

Q: If the model I need is not listed on the website, can I request a quote?
A: Yes. We hold over 200,000 SKUs of industrial spare parts in stock, and many long-tail models are not listed in full. You can send us an RFQ (Request for Quote) directly, and we will provide wholesale pricing promptly.
