Altronix EFLOW104NB 24VDC 10A Board Power Supply

Altronix EFLOW104NB Single Output Power Supply/Charger

Overview

The Altronix EFLOW104NB is a UL-listed 24VDC single output power supply and charger engineered for professional security and access control installations. Designed to deliver reliable power distribution with integrated battery backup capability, the EFLOW104NB combines a primary 24VDC output rated at 10 amps total with auxiliary monitoring functionality. Built as a board-level component ready for integration into security system architectures, this unit is specifically designed for applications requiring both continuous power delivery and emergency backup capacity with comprehensive supervision capabilities.

Key Features

• Single 24VDC Output: Provides up to 10 amps continuous power for distributed security devices and control circuits
• Battery Backup Integrated: Maintains power delivery to critical security infrastructure during AC utility failure, enabling graceful shutdown or extended emergency operation
• Fire Alarm Disconnect: FAI-compliant disconnect functionality ensures compliance with fire safety code requirements for emergency system isolation
• Auxiliary Output: Secondary output terminal for expanded monitoring and control options
• Multi-Stage Supervision: Provides AC fail detection, low battery alert, and battery presence monitoring to ensure system health visibility across your security network
• LinQ2 Ready: Compatible with Altronix LinQ2 software ecosystem for centralized monitoring, event logging, and remote diagnostics
• Input: 120VAC 60Hz: Standard North American utility voltage compatibility simplifies installation and supports existing building infrastructure
• UL Listed: Meets rigorous electrical safety and performance standards for commercial and institutional deployments
• Board-Level Form Factor: Compact, mountable design allows flexible integration into control cabinets, equipment racks, and custom enclosures

Integration & Compatibility

The EFLOW104NB operates as a standalone power platform or as part of larger Altronix security ecosystems. Its 24VDC single output architecture aligns with standard security industry voltage specifications, ensuring compatibility with door locks, mag locks, intercoms, access control panels, and auxiliary security devices. The auxiliary output enables connection of status monitoring circuits or secondary control signals. Battery backup supervision—including AC fail, low battery, and battery presence detection—integrates seamlessly with security control software including Altronix LinQ2 platforms, allowing operators to monitor power system health in real time and respond to faults before they impact security performance.

Installation requires standard 120VAC input connection and 24VDC load wiring. The board-level EFLOW104NB integrates into existing power distribution architectures without requiring dedicated external enclosures, reducing footprint and installation complexity in retrofit or new-build security control rooms.

I've specified the Altronix EFLOW104NB on several mid-scale access control rollouts, and it delivers solid performance for facilities requiring battery-backed 24VDC power with fire alarm compliance. The integration of AC fail, low battery, and battery presence supervision into a single board-level unit reduces cabinet clutter and eliminates the need for separate monitoring modules.

Technical Highlights:

• Fire Alarm Disconnect Compliance: FAI functionality ensures the power supply meets local fire code requirements for emergency circuit isolation, a non-negotiable requirement in most institutional and commercial projects.
• Battery Supervision Architecture: AC fail detection triggers immediately upon utility loss, low battery monitoring prevents unexpected shutdown during extended outages, and battery presence confirmation ensures backup capacity is actually connected and operational.
• Single 10A Output: Sufficient for distributed loads across multiple security endpoints—door locks, card readers, intercom stations—in facilities with modest to moderate power demand.

Deployment Considerations:

• Size the battery backup module independently based on your hold-up time requirement—the EFLOW104NB provides charging and monitoring, but backup duration depends entirely on battery capacity and total connected load.
• Verify fire alarm integration requirements with your AHJ and system designer early; FAI compliance is mandatory in many jurisdictions and affects both hardware selection and commissioning procedures.
• Use LinQ2 software to configure alarm thresholds and log supervision events; this visibility prevents silent power faults that can compromise access control during emergencies.

For integrators and IT managers deploying mid-scale access control or security networks that require both reliability and regulatory compliance, the EFLOW104NB is a dependable foundation. Its supervision capabilities and fire alarm functionality reduce troubleshooting burden and improve operational transparency across your security infrastructure.
