Altronix EFLOW104N16DV 16-Output 24VDC Power Supply/Charger
The Altronix EFLOW104N16DV is a 220VAC-input power supply and battery charger delivering sixteen individually PTC-protected 24VDC outputs at a combined 10A — purpose-built for commercial access control and surveillance installations where 220VAC mains are standard and per-output fault isolation is non-negotiable. If your site runs on international or industrial 220VAC power and you need a single enclosure to centralize 24VDC distribution with fire alarm integration and battery backup, this is the unit to evaluate. It is part of the Altronix power supply lineup and a member of the eFlow series.
Key Features
- 16 PTC-Protected Class 2 Outputs: Each output carries auto-resettable PTC overcurrent protection rated at 2A per output. A shorted lock or panel won't latch the output offline permanently — the PTC resets once the fault clears, which cuts truck rolls on installations with intermittent wiring faults.
- 24VDC @ 10A Total Output: Ten amps across sixteen outputs supports mixed 24VDC loads — electric strikes, mag-locks, camera power injectors, and access readers — without a secondary supply. Budget no more than 10A aggregate across all active outputs simultaneously.
- 220VAC Input with Wide Working Range (198–256VAC): The ±10% working range absorbs mains sag common in commercial facilities without nuisance shutdowns. The 5A/250V input fuse is a field-replaceable discrete component, not a resettable breaker — stock a spare on larger deployments.
- Built-in Battery Charger (1.54A Max): Supports sealed lead-acid or gel-cell batteries (sold separately); the BC300 enclosure accommodates up to two 12VDC/7AH batteries. Switchover to battery is instantaneous with no DC output interruption — critical for access control panels that latch doors on momentary power loss.
- Form C Supervision for AC Fail and Battery Fail: Both supervisory contacts report independently to your panel or monitoring system. The AC fail trigger is selectable between 30 seconds (factory) and 2 hours — useful for sites where brief utility blips should not generate alarm events.
- Supervised Fire Alarm Disconnect with 10K EOL: Supports latching or non-latching configuration on normally open or normally closed trigger — compatible with standard fire alarm panel outputs. The 10K EOL resistor enables line supervision so a cut or short in the FAI wiring is reportable.
- Low Power Shutdown: Shuts DC outputs if battery voltage drops to 70–75% of nominal, preventing deep discharge that shortens battery service life. On a site where power outages run overnight, this protection directly extends battery replacement intervals.
- NDAA, TAA, BAA, and CE Compliant: NDAA Section 889 compliance matters for federal, state, and government-contracted installations. TAA and BAA qualifications extend eligibility to GSA schedule and federal procurement. Verify these certifications are confirmed for EFLOW104N16DV specifically — they are listed on the manufacturer product page and in the known specs for this SKU.
- LinQ2 Ready: Compatible with the optional Altronix LINQ2 network communication module for remote monitoring, diagnostics, and control of power supply status — a meaningful add for enterprise deployments managed through a central platform.
Integration and Compatibility
The EFLOW104N16DV ships complete in the BC300 wall-mount enclosure with battery leads and cam lock. The enclosure provides 1/2" and 3/4" combination knockouts for conduit entry. The unit operates at an ambient range of 0°C to 49°C (32°F to 120°F) — standard for indoor electrical rooms and IDF closets. For networked power management, pair it with the Altronix LINQ2 module. Review your security power supplies selection for companion distribution hardware, and consider your access control panel wiring requirements before sizing output assignments. Consult your power planning guide for load budgeting across distributed 24VDC runs.
Frequently Asked Questions
Q: Is the EFLOW104N16DV NDAA Section 889 compliant?
A: Yes. The EFLOW104N16DV carries NDAA, TAA, BAA, and CE listings as verified on the Altronix product page. It qualifies for federal, government-contracted, and GSA-eligible installations requiring these certifications.
Q: What battery types and sizes does the EFLOW104N16DV support?
A: The built-in charger supports sealed lead-acid and gel-type batteries. The BC300 enclosure accommodates up to two 12VDC/7AH batteries. Batteries are sold separately. Maximum charge current is 1.54A.
Q: Can the AC fail supervision delay be adjusted?
A: Yes. The AC fail notification trigger is selectable between 30 seconds (factory default) and 2 hours. This allows sites with frequent brief utility interruptions to avoid nuisance alarm events.
Q: What is the per-output current rating on the EFLOW104N16DV?
A: Each of the sixteen PTC-protected outputs is rated at 2A. Total aggregate output is 10A across all sixteen outputs simultaneously.
Q: Does the EFLOW104N16DV work with Altronix LINQ2 for remote monitoring?
A: Yes. The unit is LinQ2 Ready. The optional LINQ2 network communication module connects to the eFlow series and enables remote monitoring, control, and diagnostic reporting of power supply status.
Q: What is the warranty on the EFLOW104N16DV?
A: Altronix provides a lifetime warranty on this product, as listed on the manufacturer product page.
The EFLOW104N16DV is the unit I reach for when a commercial site runs 220VAC mains and needs centralized 24VDC distribution with fire alarm integration baked in from the factory. The 10A total output across sixteen individually PTC-protected circuits gives you real fault isolation — one shorted output doesn't cascade through the panel the way a fused multi-tap can.
Technical Highlights:
- Wide 198–256VAC Input Range: Absorbs ±10% mains variance without nuisance shutdowns — practical on commercial sites where utility voltage sags under load. The discrete 5A/250V input fuse is field-replaceable; not a resettable breaker, so stock a spare in the enclosure.
- Instantaneous Battery Switchover: The integrated charger (1.54A max) keeps two 12V/7AH cells topped up in the BC300 enclosure, and switchover to battery is truly gapless — no momentary DC drop that can reset access panels or release mag-locks.
- Supervised FAI with 10K EOL: Fire alarm disconnect supports both latching and non-latching modes on NO or NC trigger, with line supervision via the 10K EOL resistor. That means a wiring cut in the FAI loop is reportable — not silent.
Deployment Considerations:
- The BC300 enclosure is rated for indoor wall mount only, operating to 49°C max — confirm your electrical room ambient before mounting in a poorly ventilated closet; 123 BTU/Hr dissipation at full load is not trivial in a sealed space.
- The aggregate 10A output ceiling is firm: sixteen outputs at 2A each exceeds the supply capacity if fully loaded simultaneously. Map your load budget before wiring — prioritize critical locks and panels, then back-fill readers and cameras with headroom to spare.
This unit is the right call for international-voltage commercial buildings — hotels, healthcare facilities, and light industrial campuses on 220VAC mains — where you need 24VDC distributed access control power in a single NDAA-compliant enclosure with fire integration already engineered in.
