Selection Guide
Use the following criteria to select the correct power supply for your ABB robot system:
- Step 1 — Identify your controller generation: IRC5 → DSQC678 (3HAC033556-001) is the standard choice.
- Step 2 — Check existing part number: If your failed unit shows DSQC627 or 3HAC020446-001, DSQC678 is the direct upgrade replacement.
- Step 3 — Confirm input voltage: Ensure site supply is 100–240 VAC before installation.
- Step 4 — Condition preference: Choose New for critical lines; Refurbished/Tested for budget-sensitive maintenance stock.
- Step 5 — Quantity & lead time: Contact us for volume pricing and expedited shipping options.

Replacement & Compatibility FAQ
Q: Is DSQC678 a direct drop-in replacement for DSQC627?
A: Yes. DSQC678 (3HAC033556-001) is the successor to DSQC627 (3HAC020446-001) and is mechanically and electrically compatible with all IRC5 controllers that used DSQC627.
Q: Can I use DSQC678 in an S4C+ controller?
A: Not directly. S4C+ uses a different power architecture. The functional equivalent is 3HC2206-1. Contact us for guidance.
Q: What is the difference between 3HAC033556-001 and 3HAC030630-1?
A: 3HAC030630-1 is an alternate assembly/revision reference within the DSQC678 product family. Both refer to the same functional unit in most IRC5 applications.
Q: Do you provide a warranty?
A: New units carry the standard ABB warranty. Refurbished and tested-used units include a 90-day Konmask operational warranty.
Q: How long does shipping take?
A: Domestic (China): 2–5 business days. International: 5–10 business days via express courier.
