Core Features & Benefits

→ Universal Input Voltage Range (100-240VAC)
Auto-ranging input eliminates voltage selection switches and simplifies global deployments. Single SKU supports facilities across North America, Europe, and Asia-Pacific regions, reducing procurement complexity and spare parts inventory by 40% compared to fixed-voltage alternatives.

✓ Conformal Coating Protection
Factory-applied coating shields internal circuitry from moisture ingress, airborne contaminants, and corrosive atmospheres common in chemical processing, wastewater treatment, and outdoor enclosures. Extends operational lifespan in environments where uncoated supplies fail within 18-24 months.

→ Redundancy-Ready Architecture
When paired with the 1606-XLERED redundancy module, two units provide automatic failover protection with zero downtime during primary supply failure. Critical for pharmaceutical batch processes, semiconductor fabrication, and 24/7 production lines where even brief interruptions trigger costly material waste.

✓ High-Efficiency Operation (91.3% at Full Load)
Reduces heat generation by 35% versus 85% efficient designs, lowering panel cooling requirements and extending component life. In a typical 10-unit installation, efficiency gains translate to $180-240 annual energy savings per panel at $0.12/kWh industrial rates.

→ Comprehensive Diagnostic Indicators
Front-panel LEDs provide instant visual confirmation of DC output status, AC input presence, and fault conditions. Accelerates troubleshooting during commissioning and reduces mean-time-to-repair by 60% compared to supplies without status indication.

✓ Remote Voltage Sensing
Dedicated sense terminals compensate for voltage drop in cable runs up to 50 meters, maintaining ±1% regulation at the load point. Essential for distributed I/O installations and remote equipment where traditional supplies experience 3-5% voltage sag.

Application Scenarios

ControlLogix PLC Installations
Serves as primary or backup power for Allen-Bradley 1756 chassis in discrete manufacturing, automotive assembly, and packaging operations. The 10A continuous rating supports fully-populated 13-slot chassis with communication modules, analog I/O, and motion control cards. Peak current capability (12A for 5 seconds) handles inrush during module hot-swap or system startup without nuisance trips.

Process Control & SCADA Systems
Powers distributed RTUs, flow computers, and analyzer systems in oil & gas midstream facilities, water treatment plants, and chemical batch operations. Conformal coating withstands H2S exposure, high humidity (95% RH non-condensing), and temperature swings from -25°C to +70°C common in outdoor enclosures and unheated equipment shelters.

Machine Builder OEM Applications
Integrates into packaging machinery, CNC machine tools, and material handling equipment where compact footprint (50mm width) and DIN rail mounting simplify panel design. UL/cUL/CE certifications streamline compliance for equipment sold into North American and European markets.

Building Automation & Infrastructure
Supports BACnet controllers, access control panels, and energy management systems in commercial facilities. Low no-load power consumption (<3W) and wide operating temperature range enable installation in unconditioned mechanical rooms and rooftop equipment enclosures.

Redundant Power Architectures
Deployed in pharmaceutical clean rooms, semiconductor fabs, and data center infrastructure where single-point failures are unacceptable. Parallel operation with diode-OR redundancy modules ensures continuous 24VDC availability even during scheduled maintenance or component failure.

Technical Parameters & Selection Guide

Selection Criteria: Choose the 1606-XLE240EE when your application requires conformal coating protection, redundancy capability, or operation in ambient temperatures exceeding 60°C. For standard industrial environments without harsh conditions, consider the 1606-XLE240E (non-coated version) at reduced cost. If load requirements exceed 10A, specify the 1606-XLE480E (480W, 20A) to maintain adequate derating margin.

Extended Functions

Parallel Redundancy Operation: Connect two 1606-XLE240EE units via the 1606-XLERED redundancy module for automatic load sharing and failover protection. Each supply operates at 50% capacity during normal conditions, providing 100% backup capacity if either unit fails. System continues operation during hot-swap replacement of failed module.

Remote Monitoring Integration: Output voltage and current can be monitored via external meters or PLC analog inputs. DC OK relay contact (available on select models) provides alarm integration with SCADA systems for predictive maintenance programs.

Custom Configurations: Factory customization available for OEM customers requiring modified output voltages (12VDC, 48VDC), extended temperature ratings (-40°C), or application-specific certifications (ATEX, IECEx, marine). Minimum order quantities and lead times apply—consult technical sales for feasibility assessment.

Delivery & Service Assurance

Lead Time: Stock items ship within 1-2 business days via DHL/FedEx with tracking. Custom configurations require 4-6 weeks factory lead time plus transit. Expedited production available for critical outages (48-hour surcharge applies).

Warranty Coverage: Comprehensive 12-month manufacturer warranty covers defects in materials and workmanship. Extended warranty programs (24/36 months) available for volume purchases and OEM integrators.

Technical Support: Access to application engineers with ControlLogix expertise for sizing calculations, redundancy design, and troubleshooting assistance. Phone/email support available during business hours (GMT+8), with 4-hour response SLA for critical production issues.

Documentation Package: Each unit ships with installation manual, wiring diagrams, dimensional drawings, and compliance certificates. CAD models (STEP, DWG) and EPLAN macros available for download from product support portal.

Frequently Asked Questions

What wire gauge should I use for 10A output connections?
Use 14 AWG (2.5mm²) minimum for runs up to 10 meters, 12 AWG (4mm²) for 10-25 meter runs to limit voltage drop below 2%. Spring-clamp terminals accept 12-22 AWG solid or stranded wire with ferrules recommended for stranded conductors.

Can this power supply operate in parallel without a redundancy module?
No—direct paralleling without the 1606-XLERED module will cause current imbalance and potential damage. The redundancy module contains diode-OR circuitry and current-sharing logic required for safe parallel operation.

How much energy savings does 91.3% efficiency provide versus 85% units?
At 240W output, the 1606-XLE240EE dissipates 23W as heat versus 42W for an 85% efficient supply. Over 8,760 annual operating hours, this saves 166 kWh per year—equivalent to $20 at $0.12/kWh rates, with additional savings from reduced cooling loads.

Is this suitable for marine or offshore platform installations?
The conformal coating provides excellent corrosion resistance, but marine certifications (DNV, ABS) are not standard. Contact factory for marine-certified variants with enhanced salt-fog testing and vibration qualification per IEC 60068-2-6.

What causes the DC output LED to flash amber?
Flashing amber indicates the supply is in current-limiting mode due to overload or short circuit. Reduce load below 10A or check for wiring faults. If the condition persists after fault removal, the unit may require service—contact technical support for RMA procedures.

Does the unit require external fusing or circuit protection?
Yes—install a 10A slow-blow fuse or 10A Type C circuit breaker on the AC input per NEC/IEC requirements. Output fusing is optional but recommended for branch circuit protection in distributed systems.
