Altronix EFLOW6N8DV 220VAC Input 8-Output Power Supply/Charger with FAI

Overview

The Altronix EFLOW6N8DV is a 220VAC-input power supply and battery charger engineered for international and export surveillance installations where North American 120VAC mains are not available. It converts a 220VAC (198–256VAC working range) 50/60Hz input into eight individually PTC-protected outputs selectable at either 12VDC or 24VDC, with a total supply current of 6A — enough headroom for eight low-draw cameras or four-to-six mid-draw devices without crowding the bus. The unit ships inside Altronix's BC300 wall-mount enclosure, which accommodates two 12VDC/7AH standby batteries and provides knockout-ready cable entry — reducing on-site enclosure sourcing to zero.

For integrators deploying Altronix power solutions internationally, the EFLOW6N8DV fits squarely in the eFlow family's 220VAC tier, providing the same supervision and diagnostics architecture used in domestic eFlow units but pre-configured for European and Middle Eastern grid voltages. It carries CE, TAA, NDAA, and BAA listings, which matter both for government-adjacent projects and for export compliance paperwork.

Key Features

• 220VAC Input with 198–256VAC Working Range: The EFLOW6N8DV accepts the full tolerance band of 220VAC mains without a separate transformer or autotransformer. Most international grids sag or surge within this band daily — the wide working range means your power supply doesn't become the weak link when building voltage fluctuates. Protected by an on-board 5A/250V fuse at the input stage.
• Eight Individually PTC-Protected Outputs at 2A Each: Each of the eight outputs uses a resettable PTC (positive temperature coefficient) device rather than a replaceable fuse. A shorted camera run or wiring fault trips only that output and resets automatically once the fault clears — no blown fuses, no service call just to restore a single zone. Total output bus is rated 6A; stay within 2A per output and the math works out across all eight without derating.
• Selectable 12VDC or 24VDC per Output: Installations mixing 12VDC cameras with 24VDC access control readers or motion detectors are common. Output voltage is selectable per-output, so you're not forcing everything onto a single rail. This eliminates the need for a separate 24VDC supply for door hardware on the same panel.
• Unswitched 1A Auxiliary Output: The aux output stays live independently of the main output bank — useful for powering a panel processor, a communication module, or a low-draw device that must remain up even during a supervised fire alarm disconnect event.
• Supervised Fire Alarm Disconnect (FAI): The fire alarm input (FAI) cuts DC outputs to door hardware or electrically controlled devices when a fire panel triggers — in latching or non-latching mode, on normally open or normally closed contacts, with a 10K EOL resistor for supervised loop integrity. This is a code requirement in most life-safety-integrated access control installations, and it's built in here rather than requiring an external relay module.
• Built-in Battery Charger with Deep-Discharge Protection: The on-board charger handles sealed lead acid or gel-type batteries up to 7AH per cell (two cells fit the BC300 enclosure) at a maximum 1.54A charge current. Automatic, instantaneous switchover to standby battery on AC fail means no output interruption. Low-power shutdown engages if battery voltage drops to 71–73% of nominal on 12V units or 70–75% on 24V units, preventing deep discharge that permanently degrades battery capacity.
• AC Fail and Battery Supervision via Form-C Contacts: Separate form-C relay contacts report AC fail (selectable 30-second or 2-hour notification delay) and battery fail/presence to the host panel or monitoring system. This gives you panel-level visibility into power health without polling a separate monitoring device.
• LinQ2 Ready: The EFLOW6N8DV is compatible with Altronix's LINQ2 network communication module, which adds remote monitoring, control, and diagnostics reporting over IP for power supply health — useful on large distributed sites where physically checking each enclosure is impractical.
• Overvoltage and Short-Circuit Protection: Overvoltage protection on the output side prevents upstream transients from reaching connected devices. Combined with per-output PTC protection and the input fuse, the protection stack covers fault conditions at every stage.
• NDAA and TAA Compliant: Verified NDAA Section 889 compliance and TAA compliance make this unit deployable on federal projects and in supply chains that require US-origin or treaty-country sourcing. CE marking addresses European regulatory requirements for the same hardware.

Integration & Compatibility

The EFLOW6N8DV integrates with the access control and surveillance power ecosystem through its supervised form-C contacts and FAI input. The LinQ2 module (sold separately) enables IP-based remote diagnostics and fits integrators running Altronix's network power management architecture on multi-enclosure sites. The BC300 enclosure uses standard 1/2-inch and 3/4-inch combination knockouts, compatible with common conduit fittings in international installations. Pair this supply with a PoE switch on the network side for camera connectivity; the EFLOW6N8DV handles the analog, access, and auxiliary DC runs that PoE doesn't reach.

Batteries are sold separately. The enclosure accepts two 12VDC/7AH sealed lead acid or gel cells — a common form factor available from most security distributors. Battery leads are included with the unit.

Frequently Asked Questions

Q: Is the EFLOW6N8DV NDAA Section 889 compliant?

A: Yes. The EFLOW6N8DV carries a verified NDAA listing, along with TAA, BAA, and CE compliance, making it suitable for federal and government-adjacent installations with supply chain restrictions.

Q: What input voltage does the EFLOW6N8DV require, and what is the working range?

A: The EFLOW6N8DV is designed for 220VAC input with a working range of 198VAC to 256VAC at 50/60Hz. It is not rated for standard North American 120VAC mains without a step-up transformer.

Q: Can each of the eight outputs be set independently to 12VDC or 24VDC?

A: Yes. Outputs are individually selectable at 12VDC or 24VDC, allowing mixed-voltage loads (cameras, readers, motion detectors) to share a single enclosure without requiring separate supplies.

Q: What happens if one output is shorted or overloaded?

A: Each output is protected by a resettable PTC device. A fault on one output trips only that channel and resets automatically once the fault clears — no fuse replacement required, and the remaining seven outputs stay active.

Q: What battery type and size does the EFLOW6N8DV support?

A: The built-in charger supports sealed lead acid or gel-type batteries. The BC300 enclosure accommodates two 12VDC/7AH batteries (sold separately). Maximum charge current is 1.54A, with automatic instantaneous switchover to standby on AC fail.

Q: Does the EFLOW6N8DV include remote monitoring capability?

A: The unit is LinQ2 Ready — Altronix's LINQ2 network communication module (sold separately) connects to the EFLOW6N8DV and enables IP-based remote monitoring, control, and diagnostics reporting for large distributed deployments.

The EFLOW6N8DV is the unit I reach for when a project ships overseas or into a facility running 220VAC distribution — the 198–256VAC working range covers the real-world voltage variance you'll see on international mains without adding an autotransformer to the BOM. Eight individually PTC-protected outputs selectable at 12 or 24VDC in a single BC300 enclosure is a clean, compact power architecture for a small-to-medium camera and access control installation.

Technical Highlights:

• FAI with EOL Supervision: The supervised fire alarm disconnect uses a 10K EOL resistor and operates on either NO or NC trigger in latching or non-latching mode — covers the majority of fire panel integrations without additional relay hardware, and the loop is supervised so a wiring fault doesn't go undetected.
• Deep-Discharge Protection at 71–73% Battery Threshold: The low-power shutdown at 71–73% of nominal battery voltage (12V units) is a meaningful protection level — it stops battery degradation before the damage accumulates, which matters when a battery replacement in an international or remote site means shipping lead time, not a quick warehouse run.
• 1.54A Charge Current for 7AH Cells: At 1.54A into a 7AH cell, you're looking at roughly a 5–6 hour recharge from full discharge. Size your expected outage durations accordingly when specifying standby time — two 7AH cells give you a reasonable buffer for overnight or weekend outages at typical surveillance loads, but won't cover multi-day grid failures without additional battery capacity elsewhere.

Deployment Considerations:

• The 6A total output is shared across all eight outputs — if you load all eight channels to the full 2A per-output rating, you exceed the 6A bus total. Plan your load distribution: four outputs at 1.5A each is safe; eight outputs at 2A each is not. Map your device draw before commissioning.
• The LINQ2 remote monitoring module is sold separately and is not included in the box. If remote diagnostics are a project requirement — which they should be on any unattended international site — budget and specify the LINQ2 at the proposal stage, not after installation.

This unit is well-matched to embassy and government facility perimeter camera systems in 220VAC regions where NDAA and TAA supply chain documentation is required, as well as international hotel or campus security installations where a single enclosure needs to feed a mix of 12VDC cameras and 24VDC door controllers without a separate supply for each voltage rail.
