Altronix EFLOW104NBV 24VDC 10A Power Supply

Altronix EFLOW104NBV Power Supply/Charger

Overview

The Altronix EFLOW104NBV is a robust power supply and charger engineered for security integration deployments requiring stable 24VDC output. This single-output unit delivers 10 amps of continuous power from a 220VAC input, making it suitable for mid-scale camera systems, door controllers, and access control infrastructure. The EFLOW104NBV incorporates auxiliary output capability, enabling simultaneous low-current loads on independent circuits. Built with battery backup architecture, this unit supports seamless failover during AC loss, critical for maintaining security system uptime in installations where continuous operation is non-negotiable.

Key Features

• Primary Output: 24VDC @ 10A single output rated for continuous operation
• Input Power: 220VAC universal input voltage acceptance
• Auxiliary Output: Secondary low-current output for independent circuit loads
• Battery Integration: Built-in charging circuit for lead-acid or sealed battery backup; supports automatic failover to battery power during AC mains failure
• FAI Compatibility: Factory-authorized integration framework enabling remote monitoring and device diagnostics
• LinQ2 Ready: Altronix proprietary network protocol support for integration with multi-unit power management ecosystems and central monitoring platforms
• Board-Level Unit: Compact footprint suitable for enclosure mounting, cabinet integration, or OEM embedding in larger security platforms
• Thermal Protection: Automatic load sensing and thermal management to prevent damage during extended operation or fault conditions

Integration & Compatibility

The EFLOW104NBV integrates directly into Altronix ecosystem deployments. FAI-certified architecture enables remote firmware updates, health monitoring, and event logging through Altronix network management interfaces. LinQ2 protocol support allows the EFLOW104NBV to communicate with compatible power distribution units, battery backup modules, and centralized supervision consoles. The auxiliary output simplifies split-load scenarios where auxiliary circuits (signage, indicators, auxiliary relays) require independent current sourcing while primary security loads draw from the main 24VDC rail. This design reduces BOM complexity in multi-load installations and simplifies troubleshooting by isolating auxiliary faults from primary camera or control circuits.

Battery Backup & Continuity

The integrated battery charger within the EFLOW104NBV ensures constant-voltage charging of connected backup batteries, maintaining readiness for AC loss scenarios. In surveillance deployments, this capability sustains camera operation, access control systems, and door locks during power interruptions, meeting uptime requirements in critical-access facilities. The charger architecture is optimized for sealed lead-acid batteries; sizing the backup battery capacity depends on connected load profiles and required runtime duration—a standard practice during system design phase.

Ted Perry

I've specified the Altronix EFLOW104NBV in several mid-scale security installations over the past two years. This power supply strikes a pragmatic balance between output capacity, auxiliary flexibility, and battery integration—all without requiring rack-mounted UPS complexity. The 10-amp output at 24VDC handles typical camera arrays (4–8 cameras) and controller loads without thermal throttling, and the auxiliary output eliminates the need for secondary power distribution in many layouts.

Technical Highlights:

• Single Output Simplicity: 24VDC @ 10A eliminates voltage conversion losses and simplifies wiring discipline across the site; no multi-voltage management overhead for integrators.
• LinQ2 Protocol: Network integration means I can monitor charger health, battery status, and output rail voltage from a central console rather than field-visiting each supply.
• Auxiliary Output Utility: Secondary load circuit prevents nuisance tripping when auxiliary devices (signage, buzzer modules, indicator relays) draw current; main camera rail stays isolated and stable.

Deployment Considerations:

• Verify 220VAC mains availability at the site during design phase; some North American facilities run 120VAC exclusively, which would require external step-up transformer or alternative supply selection.
• Size the backup battery in consultation with the customer's uptime requirement; a typical sealed lead-acid 7Ah–12Ah battery provides 15–30 minutes of emergency runtime depending on load draw—standard for access control hold-over.
• During commissioning, verify auxiliary output draw does not exceed rated current; document split load allocation to prevent future field troubleshooting ambiguity.

The EFLOW104NBV is a solid choice for integrators seeking reliable, network-aware power distribution without overspecifying for the application. Board-level construction keeps cost competitive, and FAI certification ensures long-term vendor support and firmware continuity.
