Emerson VE5132 Power Supply Redundancy Module

Configured for power distribution and load management in DeltaV bulk power systems, the Emerson VE5132 (VE5132 Power Supply Redundancy Module) provides direct physical and electrical execution of bulk DC power paralleling. This hardware component enables the consolidation and protection of redundant DC power sources within the cabinet architecture.

Hardware Specifications

Process Control and Signal Integrity

The module architecture supports the integration of redundant power paths to ensure continuous supply delivery to the system bus. By utilizing parallel diode OR-ing or similar steering circuitry, the module prevents back-feeding from a faulted power supply into the healthy rail, maintaining the stability of the distribution network. The inclusion of conformal coating provides environmental protection against airborne contaminants, ensuring consistent electrical contact and component longevity in diverse industrial atmospheres.

Frequently Asked Questions

Q: Does the VE5132 provide current limiting functionality for individual power supply inputs?

A: The module functions as a redundancy/steering component. Over-current protection remains the responsibility of the individual power supply units or external branch circuit breakers installed upstream of the VE5132.

Q: Is this module capable of being hot-swapped while the system is powered?

A: The VE5132 is designed for insertion into the power distribution assembly. Ensure all redundant power sources are verified for correct voltage potential before installation to avoid current inrush or localized arcing.

Field Installation Guidelines

• Mounting: Install the module within the designated bulk power distribution rail. Ensure all fasteners are tightened to manufacturer specifications to maintain low-impedance connections for high-current throughput.
• Grounding: Ensure the power distribution assembly chassis is connected to a verified instrument ground bus. This is necessary for protecting the internal steering diodes and circuitry from transient surge voltages.
• Wiring: Use appropriately sized cabling capable of handling the 40 A rated current capacity. Ensure cable terminations are clean and free of oxidation to prevent resistive heating at high load levels.
• Verification: Measure the output voltage at the distribution terminals post-installation to confirm that the redundant power paths are correctly balanced and functioning within the specified 12 VDC to 28 VDC input range.
