Altronix EFLOW3NX4 4-Output 12/24VDC Power Supply Charger

Altronix EFLOW3NX4 Power Supply Charger

Overview

The Altronix EFLOW3NX4 is a UL-listed power supply and charger engineered for security and fire alarm applications requiring reliable DC power distribution with integrated battery charging capability. Housed in a compact BC400 enclosure, the EFLOW3NX4 delivers 12/24VDC output at a rated 2A maximum current across four independently fused outputs, making it suitable for multi-device deployments in access control, surveillance, and emergency communication systems. The unit accepts standard 120VAC 60Hz input and incorporates automatic battery charging, fire alarm disconnect functionality, and comprehensive system supervision to meet code-mandated safety and monitoring requirements.

• Battery Backup Charging: Integrated charger automatically maintains backup battery state, enabling continued operation during AC loss
• Fire Alarm Disconnect: Built-in FAI disconnect relay complies with fire safety disconnection protocols
• AC Failure Supervision: Automatic monitoring detects and reports AC mains loss
• Low Battery Supervision: Real-time notification when backup battery reaches critical threshold
• Battery Presence Detection: Confirms backup battery presence and connectivity status
• LinQ2 Ready: Compatible with LinQ2 cloud-based monitoring and management platform for remote system oversight
• UL Listed: Meets UL safety standards for power supply applications
• Auxiliary Output: Additional output terminal for extended system integration and monitoring device connectivity
• 120VAC Input: Standard North American mains input at 60Hz
• BC400 Enclosure: Compact, space-efficient form factor suitable for mounting in control panels and equipment racks

Integration & Compatibility

The EFLOW3NX4 integrates seamlessly into security and fire alarm ecosystems requiring centralized power distribution with battery backup. The unit's four fused outputs accommodate multiple downstream devices—access control readers, door locks, intercoms, sensors, and monitoring equipment—without requiring separate power supplies at each location. Fire alarm disconnect capability allows system integrators to comply with local fire codes that mandate power removal from non-essential security circuits during alarm events. LinQ2 readiness enables cloud-connected monitoring and diagnostics, providing real-time visibility into AC mains health, battery charge state, and system faults across distributed installations. The auxiliary output supports supervision devices, relay modules, or additional monitoring equipment. Its 120VAC input makes the EFLOW3NX4 directly compatible with standard electrical infrastructure in commercial, institutional, and multi-tenant environments.

Package Contents & Specifications

Each unit ships with the power supply module, BC400 enclosure, fused output terminals, and connection documentation. Input specification: 120VAC 60Hz. Output: 12/24VDC (selectable) at 2A maximum total current. The four independent fused outputs enable granular load distribution and fault isolation. Supervision capabilities include AC fail detection, low battery alarm, and battery presence confirmation—critical for unattended remote sites and critical infrastructure where downtime notification is mandatory. Battery backup functionality preserves system operation during AC mains interruption, with automatic charging when AC is restored.

Karl Wilson

I've specified the Altronix EFLOW3NX4 in several multi-building campus deployments where distributed access control and alarm systems require centralized, supervised power. The four independently fused outputs and integrated battery charging eliminate the need for separate power supplies at remote nodes, simplifying installation and reducing point-of-failure risk. Fire alarm disconnect compliance is built in—no additional relays required—which accelerates code approval during municipal inspection.

Technical Highlights:

• Battery Backup & Charging: Automatic charger keeps backup battery ready; supervision confirms charge state and battery presence, preventing silent failures
• Four Fused Outputs: Each output independently protected; a fault downstream does not cascade to adjacent circuits
• AC Fail & Low Battery Supervision: Real-time monitoring detects mains loss and battery degradation; critical for alerting operations to maintenance needs
• Fire Alarm Disconnect: Built-in FAI relay eliminates need for external disconnect logic in fire-critical installations

Deployment Considerations:

• Verify backup battery capacity against system load and required autonomy duration before final sizing
• Confirm fire alarm disconnect wiring matches local authority jurisdiction requirements; FAI functionality is code-dependent
• Use LinQ2 integration for remote sites where manual battery inspection is infrequent; cloud monitoring ensures visibility without site visits
• Plan fused output distribution during design phase to balance load across outputs and avoid thermal stress

For integrators standardizing on Altronix chassis power across multi-site portfolios, the EFLOW3NX4 offers reliability, compliance parity, and transparent operational visibility. The combination of battery backup, integrated charging, and comprehensive supervision makes it a solid choice for mission-critical applications where AC loss cannot compromise security or life safety function.
