Altronix EFLOW6NA8 8-Output Access Power Controller

Altronix EFLOW6NA8 Access Power Controller with Power Supply and Charger

Overview

The Altronix EFLOW6NA8 is a dedicated access control power management solution designed for integrators deploying multi-output relay-based access systems. This controller combines regulated power supply and battery charging functionality in a single DIN-rail mounted platform, eliminating the need for separate power and charging components. The EFLOW6NA8 delivers consistent 12/24VDC output at 6A maximum current, making it suitable for small to mid-scale access control installations with multiple door strikes, magnetic locks, or auxiliary devices. Built into a BC400 industrial enclosure rated for field deployment, the unit supports both standard 115VAC input and includes auxiliary output connectivity for expanded system integration.

Key Features

• 8 Fused Relay Outputs: Independent relay channels with individual fusing provide circuit protection and enable control of multiple access devices simultaneously without cross-contamination between outputs
• Dual Voltage Configuration: Selectable 12VDC or 24VDC output allows adaptation to legacy and modern access control hardware on the same platform
• 6A Maximum Current Rating: Sufficient amperage for aggregated loads across relay outputs in mid-sized multi-door installations
• Integrated Power Supply and Battery Charger: Consolidated AC-to-DC conversion and battery maintenance charging eliminates separate transformer and charger procurement
• 115VAC Primary Input: Standard North American mains voltage compatibility with no exotic power supply requirements
• Auxiliary Output: Additional output terminal for integration of secondary system components or monitoring devices
• UL Listed and CE Marked: Meets North American and European safety standards for commercial security installations
• BC400 Industrial Enclosure: Ruggedized powder-coat steel housing rated for indoor mechanical rooms, electrical closets, and non-hazardous environments
• FAI (Flexible Access Interface) Compatible: Supports standard access control protocol integration for seamless communication with management platforms
• DIN-Rail Mounting: Standard industrial form factor simplifies installation in existing electrical infrastructure

Integration and Deployment Considerations

The EFLOW6NA8 functions as a centralized power distribution hub for relay-dependent access control topologies. Integrators commonly deploy this controller in scenarios where multiple electromagnetic locks, door operators, or strike plates require independent power switching and battery backup coordination. The eight isolated relay outputs eliminate single-point failure risk when one output experiences an overcurrent condition—fusing protects the relay circuit without affecting adjacent channels. The auxiliary output terminal enables connection of status monitoring sensors, alarm inputs, or secondary charging circuits, extending system flexibility without additional hardware. Compatibility with FAI-based management systems allows remote monitoring and switching control through standard network integration.

The combination of power supply and charger functionality within the EFLOW6NA8 reduces bill-of-materials costs and physical footprint in constrained electrical closet deployments. Battery backup capacity depends on attached battery specifications and total relay load; integrators should calculate connected device draw and select appropriately-sized backup batteries during system design. Standard 115VAC input voltage compatibility eliminates the need for dedicated step-down transformers in facilities with conventional North American power distribution. The BC400 enclosure provides thermal management adequate for continuous operation in standard indoor environmental conditions.

I've specified the EFLOW6NA8 in several multi-tenant commercial access deployments where distributed relay switching across multiple doors required robust central power management. This controller handles the power supply and battery charging roles simultaneously, which streamlines both procurement and installation logistics compared to separate components.

Technical Highlights:

• 8 Independent Relay Outputs: Each fused output operates independently, preventing cascading failures if one output experiences transient overcurrent. This is critical in access control where a single door strike fault shouldn't compromise the entire system.
• Dual Voltage Flexibility: The 12/24VDC selection accommodates both older 12V electromagnetic lock installations and newer 24V devices, reducing compatibility headaches during system migrations or integrations.
• Integrated Power and Charging: Consolidation of AC-to-DC supply and battery charger functionality into the EFLOW6NA8 reduces enclosure clutter and simplifies wiring diagrams.
• UL Listed and CE Marked: Regulatory compliance simplifies AHJ approval and enables deployment across North American and European markets without additional certification.

Deployment Considerations:

• Verify total relay load against the 6A maximum rating during design phase—this includes peak inrush current from magnetic locks and solenoid operators. Many integrators underestimate combined startup draw.
• Battery backup sizing should account for relay hold-time requirements and auxiliary device operation during mains loss. The charger maintains battery state, but capacity planning is integrator responsibility.
• The FAI compatibility enables centralized monitoring, but verify your access management platform version supports the EFLOW6NA8 before field deployment to avoid protocol mismatches.

The EFLOW6NA8 is a pragmatic choice for access control installations where reliability and simplified power architecture matter. Sizing the backup battery correctly and confirming platform compatibility upfront will ensure trouble-free operation.
