A phase cell packages the devices, heatsink, and associated hardware for one phase leg of the SCR conversion. Cells are replaced as an assembly, which keeps a rig moving without rebuilding a bay in the field. Confirm the model generation and cell configuration before ordering — Model 1400 and Model 1500 cells are not interchangeable.
Most people arrive at this page from a symptom, not a part number. These are the failure signatures associated with this item. They are starting points for diagnosis, not a substitute for it.
| What you are seeing | What it usually indicates |
|---|---|
| One phase leg not conducting | Device or gating fault in that cell |
| Unbalanced DC output across phases | Cell degraded relative to the others |
| Overtemperature at one cell position | Cooling or device fault localized to that cell |
| Repeated fuse loss on one leg only | Isolate to that cell before broader troubleshooting |
Revisions differ across the production life of this equipment, and on some Ross Hill items the dash suffix carries a calibration rather than a revision level. We verify the exact dash number and revision against the physical unit before quoting, and we will send photos of the plate on the unit we are offering.
Send a photo of your nameplate, or type out what it reads, and we will match the revision rather than guess at it.
Supplied as new-surplus (unused, from the secondary market), used-tested, or reconditioned, with condition disclosed before sale and photos on request. Availability on legacy Ross Hill and NOV items changes constantly — send the number and we will tell you what we can actually find rather than quote something we cannot deliver.
