Product Overview
The Emerson VE5011 is a DeltaV bulk power supply used to convert incoming electrical power into a regulated DC supply for compatible control-system equipment. In a process-control cabinet, it can support the power distribution arrangement for automation hardware, helping supply the DC power required by connected equipment.
Unlike an I/O module, the VE5011 does not acquire field signals or execute control logic. Its function is electrical power conversion and supply. This makes it relevant when building a DeltaV control cabinet, replacing a power supply in an existing installation, or checking whether the available DC supply can meet the connected equipment’s load requirements.
The VE5011’s compact form factor is useful where cabinet space is limited. Installation planning should still allow sufficient clearance for heat dissipation and wiring access. The input supply, DC output requirements, protective devices, and connected load must be evaluated together to ensure the power arrangement matches the intended application.

Product Features
24 V DC output: The power supply provides a 24 V DC output for compatible control-system loads. The total connected load should remain within the rated output capacity.
5 A output rating: The current rating helps determine whether the supply can support the intended equipment. Load calculations should include the normal operating current and any startup or transient demand.
Compact DIN-rail installation: The form factor supports installation in a control cabinet alongside other power and automation hardware. Adequate clearance should be maintained around the unit for ventilation and wiring access.
Internal input protection: Internal fuse protection helps address certain internal fault conditions. It should not be treated as a replacement for correctly selected upstream circuit protection.
Control-system power distribution: The VE5011 supplies electrical power rather than processing I/O signals. It should be evaluated as part of the cabinet’s complete power-distribution arrangement.
IP20 protection: The supply is intended for suitable protected installations. It does not provide protection against water ingress, so the cabinet environment must be appropriate for the unit.
Working Principle
The VE5011 converts incoming AC power into a regulated 24 V DC output. The connected control-system equipment draws current from this output according to its operating requirements. The supply must be selected and installed so that the combined load remains within its electrical ratings.
For example, a DeltaV control cabinet may contain control-system hardware and associated equipment that require 24 V DC power. The VE5011 can form part of the cabinet’s power arrangement, while separate controllers and I/O modules handle control execution and field-signal processing. The power supply’s output capacity must be assessed against the actual connected load rather than the number of devices alone.
During commissioning, technicians should verify the incoming supply, output voltage, wiring polarity, protective devices, and load distribution. If equipment resets or loses power intermittently, checking the DC supply and its connections is an important troubleshooting step alongside examining the connected devices.
Role in a DeltaV Control System Power Architecture
The VE5011 supports the electrical power layer of a DeltaV installation. It supplies DC power to compatible equipment, while controllers execute control strategies and I/O modules interface with field instruments. Correct power distribution helps prevent supply-related faults from affecting the wider control system.

Installation and Maintenance
- Verify the model reference: Confirm that the required unit is VE5011 and that its output ratings match the intended application.
- Check the incoming supply: Confirm that the AC source is within the unit’s permitted input range before connecting the supply.
- Calculate the connected load: Add the current requirements of all connected equipment and ensure that the total remains within the 5 A output rating.
- Inspect the mounting position: Install the unit on a suitable DIN rail in the intended orientation, with sufficient access for wiring and maintenance.
- Maintain ventilation clearance: Leave the required space around the power supply to support heat dissipation and avoid obstructing airflow.
- Verify terminal identification: Check the input, DC output, and signal terminals against the unit markings and the cabinet wiring documentation.
- Check polarity before energizing: Confirm the positive and negative DC connections to prevent wiring errors that could affect connected equipment.
- Provide suitable circuit protection: Select upstream protection appropriate to the supply, wiring, and connected load. Do not rely on internal fuse protection as the sole protective measure.
- Separate and secure wiring: Route conductors neatly, secure them against vibration, and follow the cabinet’s electrical wiring and grounding practices.
- Measure the output voltage: Before connecting sensitive loads, verify that the DC output is within the permitted range for the installed equipment.
- Check operation under load: Monitor the output during normal operation and investigate excessive voltage drop, unexpected resets, or signs of overheating.
- Inspect periodically: Check terminal tightness, wiring condition, mounting security, and ventilation. Isolate the supply as required before performing maintenance.

Technical FAQs
What is the rated output of the Emerson VE5011?
The VE5011 is specified as a 24 V DC bulk power supply rated at 5 A, corresponding to a nominal output power of 120 W. The actual connected load must remain within the supply’s permitted operating limits.
How can I determine whether one VE5011 can power several devices?
Add the current requirements of all connected devices, including relevant startup and transient loads. The total must remain within the supply’s output rating, with appropriate allowance for the operating conditions and system requirements.
Does the VE5011 perform DeltaV control logic or process field signals?
No. Its function is power conversion and supply. Control execution and field-signal processing are handled by the corresponding controller and I/O hardware.
What should be checked if connected equipment loses power intermittently?
Check the AC input, DC output voltage under load, terminal connections, wiring condition, protective devices, and total load current. Also investigate whether the connected equipment is drawing more current than the supply can support.
