With wide-range DC input acceptance, comprehensive protection circuitry, and DIN rail mounting convenience, this module integrates seamlessly into existing control cabinets while meeting stringent industrial standards for electromagnetic compatibility and thermal performance.

Core Features & Benefits

→ Precision Voltage Regulation: Maintains ±2% output stability across full load range, preventing voltage sag that causes I/O card malfunctions and communication errors in distributed control networks.

→ Wide Input Voltage Tolerance: Accepts 18-36VDC input range, accommodating battery backup systems and varying supply voltages without external regulation—reduces component count and simplifies power distribution design.

→ High-Efficiency Conversion: Achieves >85% efficiency at rated load, minimizing heat generation and reducing cooling requirements in densely packed control enclosures.

→ Multi-Layer Protection Architecture: Integrated overcurrent limiting, overvoltage shutdown, and short-circuit immunity protect downstream equipment from power anomalies, extending system lifespan and reducing unplanned downtime.

→ Extended Temperature Operation: Rated for -40°C to +70°C ambient operation with natural convection cooling—eliminates forced-air requirements in remote installations and hazardous area classifications.

→ Galvanic Isolation Barrier: 1500VDC input-to-output isolation prevents ground loop interference and protects sensitive control electronics from transient voltage spikes common in industrial power grids.

Application Scenarios

✓ Distributed Control System Cabinets: Powers DeltaV I/O cards, field marshalling panels, and local operator interfaces in refineries and chemical plants where process safety depends on continuous power availability. Eliminates single-point failures through parallel redundancy configurations.

✓ Hazardous Area Installations: Supports intrinsically safe barriers and HART communication devices in Zone 2/Division 2 classified locations. Wide temperature rating accommodates outdoor enclosures in extreme climates without thermal derating.

✓ Retrofit & Modernization Projects: Drop-in replacement for obsolete power supplies in legacy DeltaV systems (pre-2010 installations). Maintains backward compatibility while improving efficiency and diagnostic capabilities for aging infrastructure upgrades.

✓ High-Availability Architectures: Enables N+1 redundant power configurations for critical process units requiring 99.99% uptime. Parallel operation with current sharing prevents cascading failures during maintenance or component degradation.

✓ Mobile & Skid-Mounted Systems: Vibration-resistant construction and DIN rail retention withstand transportation and field deployment in modular process units, offshore platforms, and temporary production facilities.

Technical Parameters & Selection Guide

Selection Criteria: Calculate total load current including I/O cards (typically 0.5-1.5A per 8-channel card), communication modules (0.3-0.8A), and field device power (HART devices 20-40mA each). Add 25% safety margin for inrush current and future expansion. For loads exceeding 3.6A continuous, specify this SE5009 model. For redundant systems, use two modules with diode-OR configuration or active load-sharing controllers.

Extended Functions

Diagnostic Integration: Built-in status LED provides visual indication of output health (green = normal, red = fault condition). Optional alarm relay contacts (field-configurable) enable remote monitoring through DeltaV system alarms or SCADA integration for predictive maintenance scheduling.

Parallel Operation Capability: Multiple SE5009 units can operate in parallel with external current-sharing modules to achieve higher output currents (up to 18A with four modules) or implement active redundancy without single-point failures.

Conformal Coating Option: Factory-applied protective coating available for corrosive atmosphere applications (chemical vapor exposure, marine environments, wastewater treatment plants)—consult factory for part number suffix designation.

Delivery & Service Assurance

Lead Time: Stock items ship within 2-3 business days via express courier (DHL/FedEx). Custom configurations (conformal coating, extended temperature testing) require 3-4 weeks factory lead time. Expedited processing available for emergency shutdowns.

Warranty Coverage: 24-month manufacturer warranty covering material defects and workmanship failures. Warranty includes advance replacement service for critical applications—no waiting for RMA processing during unplanned outages.

Technical Support: Direct access to automation engineers with DeltaV system expertise. Pre-sales application assistance includes load calculations, thermal analysis, and redundancy architecture design. Post-sales support covers installation guidance, troubleshooting, and integration with existing infrastructure.

Documentation Package: Each module ships with installation manual, dimensional drawings (DXF/PDF), terminal wiring diagrams, derating curves, and compliance certificates (CE, UL, RoHS). CAD models and EPLAN macros available for download.

Frequently Asked Questions

Q: How do I connect the SE5009 power supply to my existing DeltaV I/O rack?
A: The SE5009 mounts on standard 35mm DIN rail adjacent to your I/O modules. Connect input power (18-36VDC) to terminals 1(+) and 2(-), then distribute 24VDC output from terminals 3(+) and 4(-) to the I/O rack power bus. Use 14-16 AWG wire for input, 16-18 AWG for output distribution. Torque terminal screws to 0.5-0.6 Nm. Always verify polarity before energizing.

Q: What is the maximum cable length I can run from the SE5009 to remote field devices?
A: For 24VDC distribution, voltage drop limits cable length. Using 18 AWG wire (10 mΩ/m resistance), you can run approximately 50 meters to a 1A load while maintaining >22VDC at the device (assuming 24V output). For longer distances or higher currents, use larger wire gauge (16 AWG for 75m, 14 AWG for 120m) or install local power supplies closer to field devices.

Q: Can this power module reduce energy consumption in my control cabinet compared to older linear supplies?
A: Yes, significantly. The SE5009's switching topology achieves 85-88% efficiency versus 40-50% for linear regulators. For a 4A continuous load, this SE5009 dissipates ~15-20W as heat, while an equivalent linear supply would waste 60-80W. Over one year of continuous operation, this saves approximately 400-550 kWh per module—reducing cooling loads and electricity costs.

Q: Is the SE5009 suitable for installation in Class I Division 2 hazardous locations?
A: The SE5009 itself is not intrinsically safe or explosion-proof rated. However, it can be installed in Class I Division 2 / Zone 2 locations when mounted inside a properly rated enclosure (NEMA 4X or IP66 minimum) with appropriate purging or pressurization systems. For intrinsically safe circuits, use this module to power IS barriers (such as Emerson KJ4110X1 series) located in the safe area.

Q: Does this power supply support hot-swap replacement without shutting down the control system?
A: In redundant configurations (two SE5009 modules with diode-OR or active redundancy controller), you can replace a failed module without interrupting power to the load. For single-module installations, you must transfer the load to a temporary power source or schedule a controlled shutdown. The module features screw terminals (not plug-in connectors), so replacement requires wire disconnection.

Q: How do I monitor the health of the SE5009 power supply through my DeltaV system?
A: The SE5009 provides a fault relay contact (normally closed, opens on fault) that can be wired to a DeltaV digital input card. Configure an alarm in DeltaV Control Studio to trigger notifications when the contact opens, indicating output overvoltage, overcurrent, or thermal shutdown. For voltage monitoring, connect the 24VDC output to an analog input card (scaled 0-30VDC) to track output voltage trends and detect gradual degradation.
