Product Overview
The ABB DSQC627 3HAC020466-001 is a power supply unit designed for ABB industrial robot controller systems, with the DSQC 627 designation identifying the assembly. ABB documentation and industry references describe it specifically as a DSQC 627 Power Supply, while application references place it within ABB IRC5 robot systems.
This unit is used to provide the required electrical supply within the robot controller architecture, making it a service-critical spare for maintenance teams supporting installed ABB robotic cells. Its relatively substantial 4.94 kg net weight and 355 mm × 199.75 mm × 99 mm dimensions should also be considered when preparing warehouse locations, shipping cartons, and replacement procedures.
For procurement, matching the complete ABB part number is important. Personally, I would verify the controller generation, connector arrangement, physical dimensions, and nameplate details before substitution rather than relying only on the DSQC designation.

Key Features and Benefits — ABB DSQC627 3HAC020466-001
- Intended for ABB IRC5 industrial robot controller applications.
- Provides a dedicated power-supply function within the controller architecture.
- Original part-number matching helps reduce mechanical and electrical compatibility risks.
- Suitable for planned maintenance and critical spare-parts inventory.
- 4.94 kg construction should be considered when handling and packaging the unit.
- The documented 355 mm height and 199.75 mm width help maintenance teams check cabinet clearance before replacement.
- Appropriate for legacy robot systems where maintaining the original controller configuration is preferable to introducing an unverified substitute.
The main procurement concern is electrical compatibility. Voltage specifications, connector assignments, and controller revision should be checked against the installed unit before energization.

Installation and Maintenance — ABB DSQC627 3HAC020466-001
Follow the ABB robot controller maintenance procedure and isolate all relevant power sources before removing the supply. Record cable locations, connector positions, grounding connections, and visible nameplate information before disassembly.
After installation, inspect connections carefully and perform the controller power-up sequence specified for the IRC5 system. Check for abnormal alarms, voltage-related faults, cooling issues, or connector heating during initial operation. Avoid installing a unit with damaged terminals, corrosion, impact marks, or evidence of overheating.
For warehouse storage, retain the unit in suitable ESD and moisture protection. Because the assembly weighs nearly 5 kg, packaging should also prevent connector impact and internal movement during transportation.
Product Warranty — ABB DSQC627 3HAC020466-001
Warranty depends on supplier condition and product status. New, refurbished, repaired, and used units should be clearly distinguished on the quotation. For critical robot-controller spares, request actual photographs, serial or identification labels, test status, and warranty terms before purchase.
The ABB DSQC627 3HAC020466-001 is best managed as a controller power-supply spare with exact part-number and hardware verification before installation.
