## Function

Power regulation and distribution board that converts input power to multiple regulated DC rails for instrument subsystems. Provides fixed and adjustable outputs within specified voltage, current, and ripple specs; implements sequencing and fault protection (OV/OC), isolation where required, and input/output filtering to minimize noise. Interfaces with the chassis backplane for rail monitoring and fault signaling, meeting thermal and EMI considerations for reliable operation in precision instrumentation.
