Emerson SE5009 DeltaV Power Supply

Configured for stable DC power distribution within DeltaV M-series system platforms, the Emerson SE5009 (SE5009 System Power Supply) provides direct physical/electrical execution.

Hardware Specifications

Process Control and DCS Power Stabilization

• 4-20 mA HART Loop Protocol Compatibility: Incorporates high-attenuation electrical filtering to prevent high-frequency noise from corrupting super-imposed HART digital data on the analog loop supply lines.
• Channel-to-Channel Isolation: Establishes continuous galvanic isolation barriers between the input supply circuits and the internal system backplane to block common-mode voltage transients.
• Voltage Regulation Loop: Utilizes active voltage clamping feedback loops to supply stable, low-noise voltage rails to adjacent controller modules despite input line fluctuations.
• Power Feed Matching: Maintains continuous load balancing when deployed in multi-module redundant carrier architectures.

Frequently Asked Questions

Q: Does the SE5009 system power supply allow live replacement (hot-swap) during operation?

A: Yes. When installed on a redundant system power carrier alongside a secondary power supply module, the SE5009 can be hot-swapped under active power without interrupting control system execution.

Q: Can the internal power protection components of the SE5009 be replaced on site?

A: No. The SE5009 is built with sealed internal thermal and overcurrent protection fuses that are non-replaceable. A tripped internal fuse requires replacing the complete module assembly.

Q: What is the nominal input requirement to power the SE5009? A: The SE5009 requires a 24 VDC nominal power source supplied via the carrier backplane termination blocks.

Field Installation Guidelines

• Module Insertion and Latching: Slide the SE5009 straight into the assigned slot on the power carrier. Press firmly until the mechanical locking latch clicks into place, confirming a complete electrical connection.
• Functional Grounding Requirements: Ensure the mounting DIN rail is connected to the plant instrument ground bus with a copper wire of at least 4.0 mm squared cross-section to optimize electrical noise immunity.
• Cabinet Venting and Thermal Clearances: Mount the power supply carrier assembly horizontally. Provide a minimum of 100 mm vertical clearance above and below the modules to permit passive convection cooling and keep temperatures below 60 deg C.
