Altronix EFLOW104NX16DV 16-Output 24VDC Power Supply/Charger with Fire Alarm Disconnect

Overview

The Altronix EFLOW104NX16DV is a wall-mount power supply and battery charger engineered for commercial access control and surveillance deployments running on 220VAC infrastructure. It takes a 220VAC input (working range 198VAC–256VAC, 50/60Hz) and distributes clean 24VDC across sixteen individually PTC-protected outputs with a 10A total supply current — enough headroom to drive a dense panel of door controllers, electric locks, or camera devices from a single unit. If you are commissioning a system in a region where 220VAC is the building standard, or integrating into a European or international installation, this is the model to reach for in the Altronix power distribution lineup.

Key Features

• Sixteen PTC-Protected 24VDC Outputs at 10A Total: Each output carries auto-resettable PTC overcurrent protection rated at 2A per channel. A shorted device resets without manual intervention or blown fuses — a practical advantage when a technician is not on-site to clear a fault at 2 a.m. The 10A aggregate lets you load the panel fully without dipping into a shared fuse pool, which simplifies load calculations during design.
• 220VAC Input with Wide Working Range (198–256VAC): The ±12% input tolerance absorbs the voltage sag common on long commercial building runs and overseas grid fluctuations without nuisance dropouts. A 5A/250V input fuse provides upstream protection, and a green AC Power LED gives a local visual confirmation that mains voltage is present.
• Built-In Battery Charger with Instantaneous Switchover: The unit charges two 12VDC/12AH sealed lead-acid or gel batteries (sold separately, housed in the same enclosure) at up to 1.54A. When AC fails, the transfer to standby battery power is instantaneous — no output interruption that would reset a controller or drop a lock. That seamless handoff matters in life-safety and access-control circuits where a power blink can create an unintended entry event.
• Low Power Shutdown at 70–75% Battery Voltage: When standby battery voltage drops below the 70–75% threshold, the unit shuts down DC output terminals before the battery reaches deep-discharge territory. Protecting the battery pack from deep discharge directly extends its service life — replacing two 12AH batteries prematurely is a non-trivial field cost.
• Supervised Fire Alarm Disconnect (FAI): The fire alarm interface supports both latching and non-latching operation, normally open or normally closed trigger logic, and uses a 10K EOL resistor for supervised loop integrity. This means the FAI input itself is monitored — a cut wire or open circuit is detectable, which is a requirement on Class A supervised circuits in many jurisdictions. AC fail and battery fail supervision use Form C relay contacts, giving your panel or monitoring head-end a dry-contact signal for both fault conditions.
• Unswitched Auxiliary Output at 1A: The auxiliary output runs continuously regardless of the fire alarm disconnect state — useful for powering a reader or sensor that must remain active even when the primary lock outputs are released during an alarm event.
• LinQ2 Ready for Remote Diagnostics: The EFLOW104NX16DV is compatible with Altronix's LINQ2 Network Communication Module (sold separately), which enables remote monitoring, control, and reporting of power supply diagnostics over IP. In a distributed facility with multiple panels, that remote visibility eliminates a truck roll to diagnose a low-battery or AC-fail condition.
• NDAA, TAA, BAA, and CE Compliant: Verified agency listings cover federal procurement requirements (NDAA Section 889, TAA, BAA) and CE for international deployments — relevant for government facilities, defense contractors, and export projects where supply-chain compliance documentation is part of the bid package.
• BC400 Wall-Mount Enclosure, Battery-Ready: The steel enclosure measures 12.25
