What it does

The bridge is where the actual power conversion happens. Thyristors fire under control of the DC module to produce variable DC for the drilling motors. Because it is a power assembly rather than a control card, failures tend to be visible and consequential: a shorted device, a failed snubber, a blown semiconductor fuse, and the affected drive is down.

FAQ

What is the Ross Hill Model 1400 SCR bridge?

Part 0001-6307-70, the thyristor bridge assembly that converts generated AC into controlled DC for the drilling motors in a Model 1400 SCR house.
