SCR & DC Drive Systems

Q: What drive systems do you cover?

Legacy SCR and DC drive systems, including modules, regulators, and power stacks.

Q: Do you handle the Ross Hill drilling drives here too?

Ross Hill drilling drives are covered under Drilling Rig Electrical; they are the same SCR family.

SCR and DC drives ran heavy industry for forty years, and plenty are still turning motors today. The control modules, regulator boards, and power stacks that keep them running are increasingly obsolete, we source them and cross-reference to equivalents.

Frequently asked

What drive systems do you cover?

Legacy SCR and DC drive systems, modules, regulators, and power stacks. This includes Ross Hill / NOV drilling drives and industrial DC drives still in service.

Do you handle the Ross Hill drilling drives here too?

Those have their own home under Drilling Rig Electrical, but they're the same SCR family, and we cross-link the two.
