Emerson VE5008 KJ1501X1-BC2 12P2186X042 System Dual DC Power Supply
The Emerson VE5008 KJ1501X1-BC2 (Part Number: 12P2186X042) is an enterprise-grade redundant dual DC power supply engineered for continuous operation in DeltaV and Ovation distributed control systems. This hot-swappable power module delivers multiple regulated voltage rails with automatic load sharing and seamless failover, ensuring uninterrupted power delivery to controllers, I/O cards, and communication interfaces in mission-critical process automation environments.
Multi-Rail Power Architecture
Unlike single-output power supplies, the VE5008 generates three independent voltage rails simultaneously: +5 VDC for legacy logic circuits, +3.3 VDC for modern microprocessors and FPGAs, and ±12 VDC for analog signal conditioning and communication transceivers. This integrated multi-rail design eliminates the need for external DC-DC converters and reduces cabinet space requirements by up to 40% compared to discrete power supply installations.
Technical Specifications

| Isolation | 3000 VAC input-to-output, 1500 VAC output-to-ground |
| Protection | Overvoltage, overcurrent, short-circuit, overtemperature |
| MTBF | >200,000 hours at 40°C (MIL-HDBK-217F) |
| Operating Temp | -10°C to +60°C ambient with derating above 50°C |
| Certifications | UL/CSA 60950-1, CE, RoHS, REACH compliant |
Redundant Operation & Failover Logic
When deployed in redundant pairs, the VE5008 modules operate in active-active load-sharing mode, with each supply delivering 50% of the system load under normal conditions. Advanced current-sharing circuitry maintains balanced loading within ±5% between modules, preventing premature aging of one supply due to unequal stress.
Upon primary supply failure, the backup module instantly assumes 100% of the load within 10 milliseconds—faster than the holdup capacitance of downstream circuits can discharge. This bumpless transfer ensures controllers and I/O modules experience zero voltage sag or reset events during power supply switchover. Front-panel LED indicators provide real-time status visualization: green for normal operation, amber for reduced redundancy, and red for critical fault conditions.
Mission-Critical Application Scenarios
DeltaV Controller Power: Provide primary and backup power to DeltaV M-series and S-series controllers, ensuring continuous process control during utility power fluctuations, maintenance activities, or component failures in refineries, chemical plants, and pharmaceutical facilities.
I/O Subsystem Redundancy: Power redundant I/O carriers, LocalBus isolators, and CHARM modules in safety instrumented systems (SIS) where loss of field I/O could trigger emergency shutdowns or compromise process safety barriers.
Communication Network Resilience: Energize redundant Ethernet switches, serial gateways, and wireless access points in distributed control networks spanning multiple process units or geographic locations.
Analyzer System Uptime: Support continuous operation of gas chromatographs, mass spectrometers, and online analyzers requiring stable multi-voltage power for microprocessor control, detector circuits, and communication interfaces.
Advanced Diagnostic & Monitoring
Embedded microprocessor-based diagnostics continuously monitor input voltage quality, output current distribution, internal temperature, and fan speed (if equipped). Predictive maintenance algorithms track cumulative operating hours, thermal stress cycles, and capacitor aging to forecast end-of-life conditions before catastrophic failure occurs.
The power supply integrates with DeltaV AMS Suite via dedicated status contacts or optional Modbus RTU interface, enabling centralized monitoring of power system health across entire control networks. Alarm outputs trigger on conditions including AC input loss, DC output undervoltage, overtemperature, and fan failure—providing early warning for proactive maintenance scheduling.
Installation & System Integration
The VE5008 mounts to standard 19-inch EIA racks or DIN rail with included mounting brackets. Hot-swap capability allows field replacement without de-energizing adjacent equipment or interrupting process control operations. Removable terminal blocks with captive screw terminals accept 12-22 AWG wire for AC input and DC output connections.
Output voltage adjustment potentiometers enable ±5% trim for compensating voltage drop in long cable runs or matching legacy equipment requirements. Parallel operation supports up to four modules for N+3 redundancy in ultra-high-availability applications such as nuclear power instrumentation or offshore platform control systems.
