Drilling Power Modules

Q: What is a drilling power module?

The SCR power module or DC drive stack that delivers regulated DC power to the rig's motors.

Q: Can you supply obsolete power modules and stacks?

Yes; new old stock, surplus, and cross-referenced equivalents.

SCR power modules and DC drive stacks that deliver rig power in Ross Hill and NOV systems.

The power modules and SCR stacks are the muscle of the drive, they take incoming AC and deliver the regulated DC that turns the big motors. When one fails, the rig stops. We source the modules, stacks, and the SCR devices inside them.

These work with the AC and DC control modules. For the broader DC drive family, see SCR & DC Drive Systems.
