New variable frequency drives for facility upgrades, backed by the same shop that still sources obsolete SCR and DC drive parts to keep older lines running.
Most suppliers handle one side of the drive world or the other. We handle both. If you are modernizing a line, we quote current-production VFDs sized to your motor. If you are holding a 30-year-old SCR system together until the next turnaround, we track down the firing board, regulator, or power stack you need. One vendor, one PO, whether the part shipped last month or hasn't been built since the 1990s.
Send a catalog number, a motor nameplate, or a photo of the drive. We decode it, confirm horsepower, voltage, and frame, and tell you what we can source and how fast.
For new installs and upgrades, we supply low-voltage and medium-voltage VFDs across the major lines, plus the soft starters, boards, and accessories that go with them. When a current model has replaced a discontinued one, we cross-reference it so you order the right drive the first time, not the one that no longer ships.
| VFD product / service | Notes |
|---|---|
| Low-Voltage AC Drives | 208V to 600V, fractional through several hundred HP. PowerFlex, ABB ACS, Yaskawa, Siemens, Eaton. |
| Medium-Voltage Drives | 2.3kV to 6.6kV drives for large motors, fans, pumps, and compressors. |
| Soft Starters | Reduced-voltage soft starters and solid-state starters for across-the-line motors. |
| Enclosed & Bypass Drives | NEMA-rated enclosed drives, bypass packages, and combination units. |
| Drive Boards & Power Parts | Control boards, gate-driver and power boards, IGBT modules, cooling fans, and capacitor kits. |
| Drive Accessories | Line and load reactors, dynamic braking resistors, EMC filters, keypads, and HIM modules. |
| Catalog-Number Decoding | Send a catalog or nameplate number and we confirm model, voltage, and HP before you buy. |
| Cross-Reference & Sourcing | Current replacements for discontinued drives, matched across brands. |

Plenty of equipment still runs on SCR and DC drives, and the OEM support behind a lot of it is long gone. This is work most suppliers will not touch. We do. We source firing boards, voltage and current regulators, SCR power stacks, gate-drive boards, and the control cards that hold these systems together, including legacy Ross Hill and NOV drilling drives.
| Legacy component | Notes |
|---|---|
| Firing / Gate Boards | SCR firing boards and gate-driver cards for DC and SCR drives. |
| Regulators & Control Cards | Voltage and current regulator boards and drive control cards. |
| SCR Power Stacks | SCR assemblies, power stacks, and bridge components. |
| Ross Hill / NOV Drilling | Legacy SCR drilling-drive modules and replacement parts. |
Send it over and we will tell you what we can source, new or obsolete.
