Altronix EFLOW6NB 6A Power Supply Charger Board

Altronix EFLOW6NB Power Supply and Charger

Overview

The Altronix EFLOW6NB is a single-output power supply and charger designed for security and fire alarm installations requiring reliable 12/24VDC power with integrated battery backup and supervision capabilities. Built on a modular board platform, the EFLOW6NB delivers 6A maximum current output from standard 120VAC 60Hz input, making it suitable for mid-range access control, surveillance, and alarm system deployments where backup power and fault detection are essential requirements.

Key Features

• Dual Voltage Output: Configurable 12VDC or 24VDC single output at 6A maximum current capacity
• Battery Backup Capability: Integrated charging and backup power support for extended runtime during AC mains loss
• Fire Alarm Disconnect: FAI (Fire Alarm Interface) disconnect functionality for compliance with safety protocols requiring emergency power isolation
• AC Fail Supervision: Automatic monitoring and detection of AC input failure with active alarm reporting
• Low Battery Supervision: Continuous monitoring of backup battery voltage with supervision output for critical alerts
• Battery Presence Detection: Integrated sensing confirms battery connectivity and status before system deployment
• Auxiliary Output: Secondary output stage for powering optional accessories or auxiliary devices
• LinQ2 Ready: Compatible with Altronix LinQ2 management and monitoring platform for networked supervision and diagnostics
• UL Listed: Meets Underwriters Laboratories safety and performance standards for power supplies in security applications
• Board-Level Form Factor: Compact PCB-mounted design integrates directly into enclosures and control panels for streamlined installations

Integration and Compatibility

The EFLOW6NB operates on standard 120VAC 60Hz utility power and is designed for integration into security and fire alarm control panels, access control systems, and surveillance infrastructure. The board-level architecture supports direct enclosure mounting, reducing footprint and simplifying wiring harness routing in confined spaces. Fire alarm and emergency egress system integration is enabled through the FAI disconnect function, allowing power-down sequencing during emergency events. LinQ2 readiness provides visibility into supply status, battery health, and fault conditions through networked management interfaces—critical for distributed installations or multi-building campuses where remote monitoring is required.

Supervision and Monitoring

Three independent supervision channels monitor system health in real time: AC presence detection triggers alerts when mains voltage is lost; low battery monitoring ensures backup power is available and charged; battery presence confirmation prevents operation with disconnected or failed batteries. These channels can be integrated with building automation systems, alarm monitoring centers, or dedicated security management platforms for comprehensive fault reporting and maintenance alerts.

James Everett

I have evaluated the Altronix EFLOW6NB during multiple control panel deployments in mixed-use commercial facilities. The combination of battery backup, fire alarm disconnect, and full supervision capabilities makes this supply a practical choice for mid-tier security and life-safety systems where redundancy and monitoring are non-negotiable requirements.

Technical Highlights:

• Single Output Configuration: The EFLOW6NB delivers 6A at either 12VDC or 24VDC—field-selectable to match installed downstream load requirements without inventory duplication.
• Three-Channel Supervision: AC fail, low battery, and battery presence detection provide granular fault visibility without additional monitoring hardware; these outputs integrate cleanly with panel alarm inputs or building management systems.
• Fire Alarm Integration: The FAI disconnect function satisfies code-level requirements for emergency power isolation in life-safety systems, reducing design iteration time during code compliance reviews.

Deployment Considerations:

• Battery backup sizing must account for connected loads and required runtime; the EFLOW6NB charges standard lead-acid or gel-cell batteries at full 6A capacity, reducing charge-up cycles and supporting larger capacity batteries than lower-amperage supplies.
• LinQ2 integration enables remote battery health trending and AC loss event logging, useful for predictive maintenance programs and reducing field service callouts for battery condition checks.

The EFLOW6NB is a reliable, purpose-built supply for security and fire alarm applications. Its modular design, broad supervision capability, and LinQ2 readiness justify its position in control panel designs where long-term monitoring and fault transparency are expected.
