Function and Working Principle
The AEPV7D-216 operates as a dual-path power bus distribution unit within Yokogawa control systems.
Its working process includes:
- Receiving power from two independent AC input sources (A and B)
- Internally separating distribution paths for redundancy
- Supplying multiple output channels to system modules
- Allowing independent operation of each power line
- Supporting combined output configurations when required
This architecture ensures uninterrupted power delivery even if one input path fails, improving overall system reliability.
