Altronix EFLOW4N8 Power Supply Charger

Overview

The Altronix EFLOW4N8 is a dedicated 12/24VDC power supply and charger designed for security and access control system integration. Operating from 120VAC 60Hz input, the EFLOW4N8 delivers regulated output at selectable 12 or 24VDC with a maximum 4A total capacity. This unit is housed in the Altronix BC300 enclosure and includes battery backup capability, fire alarm disconnect functionality, and comprehensive supervision monitoring. UL Listed for safety-critical applications, the EFLOW4N8 serves as a reliable backbone for distributed power distribution across security installations.

Key Features

• 8 Fused Outputs: Distributes power through eight individually fused circuits, enabling independent load management and fault isolation across connected devices.
• Dual Voltage Output: Selectable 12VDC or 24VDC configuration accommodates equipment with different voltage requirements without secondary conversion.
• 4A Maximum Current: Supports aggregate loads up to 4A per voltage rail, sufficient for mid-scale access control, intrusion detection, and auxiliary device circuits.
• Battery Backup Integration: Built-in charger maintains backup battery state of charge, ensuring continuity during AC mains failure and enabling graceful system shutdown sequences.
• Fire Alarm Disconnect: Dedicated fire alarm supervision output with integrated disconnect function meets life safety code requirements for emergency power management.
• AC Fail & Low Battery Supervision: Continuous monitoring of input AC voltage and backup battery charge state provides real-time status feedback to connected control systems.
• Battery Presence Detection: Automatic supervision confirms battery installation and connectivity, preventing operation without backup power when required.
• UL Listed Certification: Meets rigorous electrical safety and performance standards required for security and fire alarm system applications.
• LinQ2 Network Compatible: Integrates with Altronix LinQ2 networked power management infrastructure for centralized monitoring and control across distributed sites.
• Compact BC300 Enclosure: Mounts in standard electrical cabinet space, simplifying installation in retrofit and new construction projects.

Integration & Compatibility

The EFLOW4N8 integrates seamlessly with Altronix access control platforms, intrusion detection systems, and auxiliary device circuits. The unit's fire alarm disconnect output and supervision functions meet requirements for life safety integration. Battery backup charger functionality supports extended runtime and controlled shutdown sequences during AC power loss. The unit's LinQ2 network compatibility enables remote monitoring and supervision status reporting through networked security management platforms, supporting multi-site oversight and automated alerting for critical power events.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The Altronix EFLOW4N8 addresses a common integration challenge in distributed security deployments: delivering reliable, regulated power to multiple circuits while maintaining backup continuity and life safety compliance. During a recent access control expansion, the EFLOW4N8's eight fused outputs proved critical for isolating load faults without cascading system failures. The dual voltage flexibility streamlined device procurement across a heterogeneous environment mixing legacy 12VDC readers with newer 24VDC IP-based devices.

Technical Highlights:

• Output Architecture: 8 individually fused circuits allow granular power distribution without shared fault points, reducing troubleshooting complexity in live security environments.
• Battery Supervision: Integrated AC fail, low battery, and battery presence detection provides three-layer redundancy in backup power confirmation—essential for fail-safe system validation.
• Fire Alarm Integration: Dedicated fire alarm disconnect output with supervised functionality meets life safety code integration requirements without additional relays or external logic.

Deployment Considerations:

• Plan fuse ratings carefully across the 4A aggregate capacity; individual circuit load analysis prevents nuisance trips on high-inrush devices like solenoid locks.
• Ensure backup battery selection matches the runtime requirement for your access control architecture—UPS-grade lithium or sealed lead-acid packs are commonly paired for 4+ hour hold-up scenarios.

For integrators managing mid-scale security deployments requiring both regulated auxiliary power and life safety compliance, the EFLOW4N8 delivers the supervision granularity and distributed output architecture that field installations demand. LinQ2 network integration simplifies multi-site monitoring without requiring dedicated serial connections or polling infrastructure.
