Altronix EFLOW6N16V 16-Output Power Supply with Battery Backup
Overview
The Altronix EFLOW6N16V is a 16-output distributed power supply engineered for security system installations requiring centralized power distribution with integrated battery backup and failsafe supervision. Drawing 120VAC 60Hz input power, this UL Listed unit outputs 12/24VDC at 6A total capacity across 16 independently fused channels, making it ideal for multi-zone access control, alarm monitoring, and fire alarm systems requiring coordinated power management and status reporting.
The EFLOW6N16V delivers redundancy through battery backup capability and intelligent supervision logic that monitors AC mains availability, battery condition, and power rail integrity. Each output channel is individually protected by a dedicated fuse, isolating faults and preventing cascading failures across the security infrastructure.
Key Features
- 16 Independently Fused Outputs: Each channel is individually protected, enabling modular power distribution and fault isolation without affecting adjacent circuits.
- 12/24VDC Selectable Output: Dual-voltage configuration supports legacy 12VDC equipment and modern 24VDC devices on the same platform.
- 6A Total Current Rating: Distributed across 16 channels provides controlled power allocation for proportional loading across multi-device deployments.
- Battery Backup Capability: Integrated battery charging and monitoring ensures critical security loads remain powered during AC mains failure, extending operational runtime based on battery capacity and load profile.
- Fire Alarm Disconnect Function: Engineered for fire alarm system integration; automatically disconnects non-essential loads during alarm conditions per fire safety requirements.
- Multi-Parameter Supervision: Real-time monitoring of AC mains status, low battery condition, and battery presence delivers visibility into power system health and triggers alerts for intervention.
- UL Listed Design: Meets electrical safety standards for commercial and industrial security applications.
- 120VAC 60Hz Input: Standard North American mains voltage compatibility; no step-down transformer required in standard installations.
Integration & Compatibility
The EFLOW6N16V integrates seamlessly into control systems architecture where distributed power with fault isolation is critical. The supervision outputs (AC fail, low battery, battery presence) connect directly to security control panels, fire alarm control units, and management software platforms that require real-time power system status. The 16-channel output architecture supports both legacy parallel-wired systems and address-intelligent devices operating on common 12/24VDC rails.
Fire alarm integrators benefit from the dedicated fire alarm disconnect relay, which ensures code compliance by isolating non-life-safety loads when alarm conditions are triggered. Access control installers leverage the 16 independent fuses to protect card readers, electric locks, REX buttons, and intercom modules without requiring external distribution blocks.
Typical Applications
- Multi-door access control systems with distributed readers and lock hardware
- Fire alarm system auxiliary power with failsafe load shedding
- Integrated alarm and CCTV power distribution in small-to-medium facilities
- Intercom and door phone power in multi-unit residential or commercial buildings
- Backup power for emergency egress lighting and exit device monitoring

I've specified the Altronix EFLOW6N16V on multiple projects where distributed power with independent channel protection was non-negotiable. The 16-channel architecture with individual fuses eliminates the single point of failure risk that comes with larger consolidated supplies, and the battery backup supervision gives the control panel real visibility into what's happening on the power rails.
Technical Highlights:
- Modular Fault Isolation: Each of the 16 outputs is independently fused, so a short on one lock circuit doesn't kill power to 15 other devices. In a 30-device facility, that's a major reliability gain.
- Battery Supervision Integration: AC fail, low battery, and battery presence monitoring feed directly into the control panel's power management logic, enabling graceful shutdown or load shedding rather than unexpected downtime.
- Fire Alarm Compliance: The dedicated fire alarm disconnect relay ensures that when a fire condition is triggered, non-emergency loads drop off and battery reserve is preserved for life-safety devices only.
- Voltage Flexibility: 12/24VDC selection means you can deploy on older 12V infrastructure or migrate to 24V without changing the power supply, reducing long-term hardware churn.
Deployment Considerations:
- The 6A total budget across 16 channels works best in facilities where average per-channel load is under 400mA. If you have five 1A devices, plan additional supply capacity or load segregation.
- Battery sizing is critical: confirm the UPS battery capacity against your runtime requirement (typically 8–24 hours for access control, longer for fire systems). Undersized batteries defeat the backup purpose.
- Install the EFLOW6N16V in a climate-controlled enclosure to preserve battery lifespan; heat degrades charge cycle life significantly, especially in summer installations.
For integrators working in multi-tenant or campus environments where power distribution must be resilient and granular, the EFLOW6N16V remains a field-proven choice. The independent fuse architecture and supervision feedback make troubleshooting faster and reduce the risk of cascading failures that can compromise security operations.
