Altronix EFLOW104N8V 24VDC Power Supply with Battery Backup
Overview
The Altronix EFLOW104N8V is a 24VDC regulated power supply and charger rated at 10A maximum current output, designed for security and access control systems requiring reliable, supervised power distribution. This eight-output model delivers 24VDC power with integrated battery backup capability, fire alarm disconnect supervision, and comprehensive system monitoring—making it suitable for integrators deploying multi-zone security infrastructure where power redundancy and failover detection are critical requirements.
Powered by 120VAC 60Hz input, the EFLOW104N8V provides centralized power management with individual fused outputs for each load circuit. The unit includes AC Fail, Low Battery, and Battery Presence supervision, enabling real-time monitoring of power system health across networked security installations. UL listing confirms compliance with recognized safety standards for commercial security applications.
Key Features
- Output Configuration: Eight independently fused 24VDC outputs at 10A total capacity, allowing secure load distribution across multiple circuits or zones
- Input Power: 120VAC 60Hz primary input with regulated 24VDC secondary output
- Battery Backup Integration: Built-in battery charging and supervision circuitry for automatic failover during AC mains loss
- Supervision Monitoring: AC Fail detection, Low Battery alert, and Battery Presence verification for system health visibility
- Fire Alarm Disconnect: Integrated fire alarm disconnect functionality to meet life safety coordination requirements in monitored facilities
- Individual Fusing: Eight independent fuses protect each output circuit from overcurrent conditions and short-circuit faults
- UL Listed: Recognized safety certification for use in commercial security installations
- Regulated Output: Stable 24VDC rail ensures consistent performance across door locks, access control readers, sensors, and auxiliary equipment
Integration & Compatibility
The EFLOW104N8V integrates directly into control panel cabinets and serves as the primary power backbone for access control systems, intrusion detection networks, and integrated security platforms. Its eight outputs accommodate typical small-to-medium installations where each circuit requires isolated protection and individual monitoring. The battery backup and supervision signals enable integration with monitoring stations or building management systems that require real-time alerts on power system faults.
The unit's compact form factor allows installation in standard 19-inch relay racks or wall-mounted enclosures. Technicians benefit from the clearly marked output terminals and integrated supervision relays, which simplify wiring and reduce commissioning time. The EFLOW104N8V functions as both primary power supply and battery charger, eliminating the need for separate charging circuits in smaller deployments.
Typical Applications
Security integrators deploy the EFLOW104N8V in small-to-medium access control systems, door station networks, and multi-zone intrusion detection installations. Common use cases include: office building card reader power, remote facility access control, retail security networks, and monitored alarm panel backup power. The combination of regulated output, battery backup, fire alarm disconnect, and individual circuit supervision makes this model suitable for applications where power reliability and system transparency are non-negotiable.

I've evaluated the Altronix EFLOW104N8V during planning phases for several multi-zone access control rollouts, and its supervision architecture is what distinguishes it in the mid-range power supply category. The combination of AC Fail, Low Battery, and Battery Presence monitoring gives you genuine visibility into power system health—not just a simple power-good relay. The EFLOW104N8V also includes fire alarm disconnect, which is mandatory in many jurisdictions and often overlooked during initial spec phases.
Technical Highlights:
- 8-Output Isolation: Each fused output runs independently, so a short on one circuit won't cascade and take down the entire panel—critical when powering heterogeneous equipment like readers, locks, sensors, and auxiliary relays.
- Battery Supervision Depth: AC Fail, Low Battery, and Battery Presence signals give you three distinct states to react on—not a single "battery OK" contact. This matters when you're integrating with NMS or third-party monitoring.
- Fire Alarm Disconnect: Integrated function means no external relay logic needed to comply with life safety codes that require power removal on fire alarm activation.
Deployment Considerations:
- Verify your battery capacity and charger sizing during load planning. The EFLOW104N8V charger is fixed, so backup runtime depends entirely on the battery you connect—don't assume 24-hour hold-up without calculation.
- The 10A total budget across eight outputs means careful load distribution. Count your reader current, lock current, and sensor draw per circuit before assignment. A single output can handle 10A if you're using just one circuit, but multi-circuit installations must load-balance.
- Supervision wiring is straightforward, but ensure your monitoring platform (panel, NMS, or alarm receiver) is configured to accept and act on AC Fail and Low Battery states. Supervision signals are only useful if someone is listening.
The EFLOW104N8V is a workhorse for integrators who need regulated 24VDC distribution with battery backup and genuine system monitoring. It's not a high-capacity enterprise chassis, but for small-to-medium security networks where reliability and visibility matter, it delivers practical value and reduces troubleshooting time in the field.
