System Role & Functional Behavior
The DS200EXPSG1ACB operates as the central power distribution hub in Mark V systems:
- Converts AC input into stable DC power rails
- Supplies power to CPU, I/O, and communication modules
- Maintains voltage stability under load fluctuations
- Supports redundancy for uninterrupted turbine operation
- Monitors internal power health in real time
- Protects downstream electronics from electrical faults
It is essentially the energy foundation of the Mark V control architecture.
