The Emerson VE5135 is an advanced DeltaV Bulk Power Supply Redundancy Module designed to ensure uninterrupted DC power delivery in high-availability industrial automation systems. It enables seamless redundancy between dual 12–28 VDC power sources, protecting critical control infrastructure from unexpected power loss.
Built with active MOSFET-based power path control, the VE5135 significantly improves efficiency and reduces voltage drop compared to traditional diode OR-ing solutions. This results in lower thermal stress, higher system efficiency, and improved long-term reliability in continuous industrial operation.
The module is widely deployed in mission-critical DeltaV architectures where power stability directly impacts process safety, production continuity, and system uptime.
