Description

Product Overview

The ABB DSQC626 3HAC026289-001 is an IRC5 drive system power supply, identified by ABB as DSQC 626A Power Supply. It is used within ABB IRC5 robot controller and drive-system architectures to provide the required electrical supply for the drive section of the robot controller. ABB documentation lists this part as a drive system power supply for the IRC5 panel-mounted controller, while ABB product data identifies 3HAC026289-001 as the current product ID replacing 3HAC020465-001.

This makes the unit an important spare for robotic maintenance teams supporting legacy IRC5 installations. Power-supply faults can affect controller startup, drive availability, and overall robot operation, so correct identification is essential before replacement. Personally, I would confirm the controller configuration and existing power-supply part number before installing a replacement, particularly when maintaining older IRC5 systems.

Technical Specifications

ABB’s official product data identifies the item as a DSQC 626A Power Supply and notes 3HAC020465-001 as the replaced product ID. Third-party dimensional and weight data varies by source, so those physical figures should be treated as reference values rather than certified installation dimensions.

Key Features and Benefits

• Designed for ABB IRC5 robotic control systems.
• Provides power for the robot drive-system section.
• Listed by ABB as a dedicated IRC5 spare part.
• Replacement for the earlier 3HAC020465-001 power-supply version.
• Suitable for planned maintenance and corrective replacement of failed drive-system power supplies.
• Helps maintain the existing IRC5 controller architecture without changing the complete drive module.
• Appropriate for critical-spares inventory supporting ABB industrial robots.

A key procurement detail is the suffix and revision. DSQC626 and DSQC626A should not automatically be treated as identical simply because the family designation is similar; ABB’s product records specifically identify 3HAC026289-001 as DSQC 626A and as the replacement for the older 3HAC020465-001.

Related Models

3HAC020465-001: Earlier ABB DSQC 626 power supply used in IRC5 systems. ABB-related documentation identifies 3HAC026289-001 as its replacement product ID.

DSQC627 / 3HAC020466-001: IRC5 drive system power supply extension associated with the drive module spare-parts list. It serves a different function and should not be assumed interchangeable.

DSQC618 / 3HAC14549-1: IRC5 rectifier used within the drive-system power architecture.

DSQC617 / 3HAC025338-001: Main servo drive unit used with selected IRC5 drive configurations. It is a separate drive component rather than a power-supply replacement.

Installation and Maintenance

Before installation, isolate the controller and follow the applicable ABB safety procedures. Verify the part number, connector arrangement, mounting configuration, and controller variant against the installed unit.

During replacement, inspect power connectors and associated harnesses for heat damage, looseness, contamination, or mechanical wear. After installation, verify controller power-up behavior and confirm that the drive system initializes normally before returning the robot to production.

For warehouse storage, keep the unit protected from dust, moisture, electrostatic discharge, and mechanical shock. Record the exact ABB part number and revision on the inventory record. This is especially useful for older IRC5 systems where multiple generations of power-supply hardware may be encountered.

Product Warranty

Warranty terms depend on the supplier and the condition of the unit. New, factory-sealed, used, refurbished, and repaired units may carry different warranty periods, so the commercial condition should be documented before purchase.

For ABB DSQC626 3HAC026289-001, the most important acceptance checks are exact part-number verification, physical condition, test status, and confirmed compatibility with the target IRC5 controller.
