Altronix EFLOW102NB 12VDC 10A Board Power Supply

Altronix EFLOW102NB Power Supply/Charger

Overview

The Altronix EFLOW102NB is a single-output, 12VDC power supply and charger designed for security systems requiring integrated battery backup and fire alarm circuit supervision. This board-mount unit delivers 10A maximum output current from 120VAC 60Hz input, making it suitable for mid-scale access control, surveillance, and alarm system deployments. The EFLOW102NB includes auxiliary output capability and FAI (Fire Alarm Interface) readiness, supporting modern integration standards including LinQ2 compatibility for streamlined system configuration.

Key Features

• Single 12VDC Output at 10A: Supplies regulated power to security devices, access control hardware, and alarm system components with sufficient current headroom for multi-device applications.
• Battery Backup Capability: Integrated charger automatically manages backup battery float and charging, maintaining system availability during AC loss events.
• Fire Alarm Disconnect: Automatic load shedding on fire alarm activation ensures power routing compliance with fire code requirements.
• AC Fail Supervision: Real-time monitoring of input AC voltage with status reporting; triggers backup power seamlessly upon AC loss.
• Low Battery Supervision: Continuous monitoring of backup battery condition prevents system failure due to depleted battery reserves.
• Battery Presence Detection: Confirms backup battery installation and readiness, alerting to missing or failed batteries.
• Auxiliary Output: Secondary power output for control circuits, relay drivers, or supplementary loads.
• LinQ2 Ready: Supports Altronix LinQ2 protocol for centralized power monitoring and diagnostics across networked security infrastructure.
• UL Listed: Third-party certification confirming safety and performance standards for security and fire alarm applications.
• Board-Mount Form Factor: Compact design enables integration into custom enclosures and OEM security appliances.

Integration & Compatibility

The EFLOW102NB integrates into security system designs requiring both primary power conditioning and battery-backed availability. Fire alarm circuit supervision via FAI ensures compliance with NFPA 72 supervision requirements. Aux output enables flexible load management—supporting relay coils, indicator circuits, or secondary supply rails. LinQ2 readiness positions the unit within modern networked power management ecosystems, allowing remote status monitoring and battery health trending.

Board-mount installation suits both OEM manufacturing and integrator custom panel builds. The 120VAC 60Hz input standard simplifies site power sourcing in North American deployments. AC fail and low battery supervision signals integrate directly into control system logic, enabling automated response protocols—emergency announcements, door unlock sequences, or escalation alerts.

Typical Applications

Deploy the EFLOW102NB in access control systems requiring battery-backed power during outages, alarm monitoring stations needing UPS-backed supervision circuits, and security appliances—such as intercoms, video encoders, or control hubs—requiring integrated charging. Multi-device installations benefit from the 10A output capacity and auxiliary output flexibility. Fire alarm interface compliance makes the unit suitable for integrated fire/security systems where power must shed on alarm activation.

Marty Allison

I've specified the Altronix EFLOW102NB in several mid-scale access control retrofit projects, and it delivers the balance of feature density and reliability that integrators need. The combination of 10A output, battery charging, and fire alarm interface in a board-mount package eliminates the need for multiple component sourcing.

Technical Highlights:

• Power Capacity & Supervision: 12VDC at 10A output handles access readers, electric strikes, and alarm devices simultaneously, with AC fail and low battery supervision preventing silent failures.
• Fire Code Compliance: Fire alarm disconnect feature ensures automatic load shedding meets NFPA 72 requirements for integrated fire/security installations.
• Aux Output Flexibility: Secondary output supports relay drivers, status LEDs, or control circuit loads without reducing primary output capacity.

Deployment Considerations:

• Verify backup battery amp-hour rating and connector compatibility before ordering; the charger circuit requires matched battery chemistry (typically sealed lead-acid).
• LinQ2 integration enables remote battery monitoring—particularly valuable in distributed security systems where on-site inspection intervals are lengthy.

The EFLOW102NB is a solid choice for integrators standardizing on Altronix platform components. UL listing and proven supervision architecture reduce commissioning risk and support long-term system availability.
