Product Introduction
ABB DASA110 3ASC25H705/7 is an ABB Advant OCS module used as a power supply and control-related component in industrial automation systems. It is commonly sourced as an OEM replacement for legacy ABB installations where exact part matching matters.
This part is usually selected when the priority is keeping the original control architecture intact. Confirm the full ordering code, cabinet fit, and system compatibility before purchase, because ABB legacy module variants can look similar but behave differently in the rack.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Module appears dead | Upstream supply loss | ✅ High | Measure input voltage at the terminals with a multimeter | Check fuses, cabinet supply, and wiring first |
| Output or control section unstable | Internal power stage fault | ✅ High | Check indicator behavior and compare against a known-good unit | Replace if supply and wiring are confirmed good |
| System will not boot after install | Wrong variant or seating issue | ✅ High | Verify the exact suffix and reseat the module | Recheck the part number and rack alignment |
| Intermittent operation | Loose connector or poor grounding | ⚠️ Medium | Inspect connectors, terminal tightness, and ground path | Tighten and re-terminate before replacing hardware |
| Overtemperature alarm | Poor cabinet ventilation or overload | ⚠️ Medium | Measure enclosure temperature and load current | Fix cooling and load conditions first |
| Nearby modules also misbehave | Rack or backplane issue | ❌ Low | Test adjacent slots and backplane power | Do not assume this module is the root cause |
If the fault is still unclear, contact technical support with photos, wiring details, and diagnostic logs.

Frequently Asked Questions
Q: Is DASA110 still available as new stock?
A: Sometimes, but availability is usually limited to surplus or secondary-market inventory. Treat it as a legacy item, not a guaranteed replenishable part.
Q: Is DASA110 the same as 3ASC25H705/7?
A: DASA110 is the model designation, and 3ASC25H705/7 is the ordering code. You should match both when sourcing a replacement.
Q: Can I swap it into any ABB drive cabinet?
A: No. Legacy ABB parts are not plug-compatible across every system. Verify the exact controller or drive family before ordering.
Q: Is it hot-swappable?
A: Do not assume so. Power down first unless the official ABB documentation for your exact system explicitly allows live replacement.
Q: Why is surplus pricing lower than factory pricing?
A: Because it usually comes from excess stock, retired systems, or secondary channels. Lower price is normal, but only if the seller is clear about condition and testing.
Q: What condition should I expect?
A: The safest descriptions are New Original, New Surplus, or Refurbished (tested). If the listing is vague, ask for photos, label shots, and test proof.
Q: What usually causes “module failure” symptoms that are really site issues?
A: Bad supply voltage, loose wiring, poor grounding, and the wrong variant are the common ones. I would verify those first before condemning the module.
