Altronix EFLOW104NX8SD 24VDC 10A 8-Output Power Supply with Battery Backup
Overview
The Altronix EFLOW104NX8SD is a 24VDC, 10-amp power supply and distribution unit designed for multi-device access control and video surveillance installations where you need clean, regulated power delivered to up to eight separate field devices — readers, locks, cameras, or detection sensors — from a single enclosure with integrated battery backup capability. If you're commissioning a mid-sized access control deployment or a camera run that demands reliable, independently fused power at each output rather than a single shared rail, the EFLOW104NX8SD is the model to spec.
The unit ships with a BC400 battery charging circuit, which means it can maintain a standby battery (sold separately) without any external charger — a meaningful simplification for installations in utility rooms where panel space and component count matter. With 14 lbs of total system weight, this is a purpose-built, rack- or wall-mountable power distribution appliance, not a lightweight desktop supply.
Key Features
- 24VDC Regulated Output: A stable 24-volt output is the standard operating voltage for the majority of commercial electromagnetic locks, electric strikes, and 24V-rated IP cameras. Deploying at 24VDC rather than 12VDC also extends usable wire run distances before voltage drop becomes a performance issue — a real factor on longer cable pulls across large facilities.
- 10A Total Capacity: Ten amps at 24VDC delivers 240 watts of available power across all eight outputs combined. For reference, a typical mag-lock draws roughly 0.5A at 24VDC, meaning this supply can comfortably support eight locks simultaneously with headroom remaining for auxiliary devices or inrush current at door-release events.
- 8 Individually Distributed Outputs: Eight discrete output terminals let you assign one device or one zone per circuit. When a single field device faults or shorts, only that output is affected — the remaining seven keep operating. This is the operational difference between a professional multi-output supply and a single-rail distribution block where one fault can take down an entire access floor.
- Integrated BC400 Battery Charger: The built-in BC400 charging circuit keeps a standby battery topped off automatically. When primary AC power fails, the system transitions to battery without requiring a separate charger module, a transfer relay, or additional wiring. For installations with any life-safety adjacency — stairwell access, data center entry points, parking structures — this on-board backup capability directly affects your UL or code compliance posture.
- Altronix EFLOW Platform: The EFLOW series is Altronix's encapsulated power distribution line, built for integration into access control and surveillance panels where the power supply and the controller share an enclosure. This matters for integrators building tidy, code-compliant panels: power, distribution, and backup in one unit reduces the number of separately listed components in the panel and simplifies the inspection record.
- 14 lb Installed Weight: At 14 lbs, the EFLOW104NX8SD is substantial enough to accommodate a full enclosure with battery, but you'll want to confirm your backbox or rack rail is rated for the combined load with battery weight added. Spec your mounting hardware accordingly before commissioning.
Integration & Compatibility
The EFLOW104NX8SD is designed to pair with Altronix's broader line of Altronix access control power products, including compatible enclosures and relay modules from the EFLOW ecosystem. As part of the access control power supply category, it fits installations running Lenel, Software House, Genetec, or comparable enterprise access platforms — the supply itself is controller-agnostic; what matters is that your controller and lock hardware is rated for 24VDC operation.
When planning a access control system deployment, cross-reference your lock manufacturer's current draw specs and your run lengths against available output capacity. If you're running eight full-draw locks at 500mA each, that's 4A peak — well within the 10A ceiling, but you'll want to document the per-output load in your panel schedule for future service calls.
For installations requiring both power distribution and network connectivity at the panel, consider pairing with a PoE switch for IP-connected readers or cameras that share the same closet. Keeping AC-powered and PoE-powered devices on separate distribution paths reduces ground loop risk and simplifies troubleshooting.
Frequently Asked Questions
Q: What is the total current capacity of the EFLOW104NX8SD?
A: The EFLOW104NX8SD provides 10 amps total at 24VDC, distributed across 8 outputs. Individual output loads must not exceed the 10A aggregate supply rating.
Q: Does the EFLOW104NX8SD include a battery? What size battery is recommended?
A: The unit includes an integrated BC400 battery charger circuit but does not include a battery. A compatible sealed lead-acid (SLA) standby battery must be purchased and installed separately. Consult the Altronix enclosure specifications for maximum supported battery dimensions and amp-hour rating.
Q: Can the EFLOW104NX8SD power both access control locks and cameras simultaneously?
A: Yes, provided the devices you are powering operate at 24VDC and the combined current draw of all connected devices does not exceed 10A. The 8 separate outputs allow you to mix device types across circuits.
Q: Is the EFLOW104NX8SD suitable for use in access control panels with UL-listed requirements?
A: The EFLOW series is designed for integration in access control enclosures. Verify the specific UL listing status and listing category for this SKU against your jurisdiction's AHJ requirements before final panel design.
Q: What enclosure does the EFLOW104NX8SD mount into?
A: The EFLOW104NX8SD is designed for use with compatible Altronix enclosures from the EFLOW platform. Confirm enclosure model compatibility directly with Altronix documentation before ordering, as enclosure fit depends on the specific EFLOW board form factor.
Q: What is the output voltage of the EFLOW104NX8SD?
A: The EFLOW104NX8SD outputs regulated 24VDC. This matches the operating voltage of the majority of commercial electromagnetic locks, electric strikes, and many 24V-rated surveillance devices.
The EFLOW104NX8SD is a unit I'd reach for on any mid-sized access control commission where you're running more than four doors from a single power closet and don't want to argue with the AHJ about having a standalone battery charger sitting loose in the panel. The 10A at 24VDC headroom is generous for eight-door deployments, and the integrated BC400 charger keeps the BOM and the panel schedule clean.
Technical Highlights:
- 24VDC / 10A Regulated Output: 240 watts of available capacity across eight circuits — enough to run eight standard mag-locks at roughly 500mA each with 6A still in reserve for auxiliary devices, door position sensors, or reader power.
- 8 Independent Outputs: Per-output distribution means a field fault — a shorted lock, a pinched wire — stays isolated to that circuit. The remaining seven outputs keep your access points operational while you troubleshoot, which matters at 2 a.m. when a dock door faults during a shift change.
- Integrated BC400 Battery Charging: The on-board charger eliminates the external charger module most competing designs require. Fewer listed components in the panel, fewer wiring terminations, simpler commissioning documentation — all of which affect your installation labor budget and the inspector's sign-off timeline.
Deployment Considerations:
- The unit weighs 14 lbs without a battery installed. Factor the standby battery weight into your enclosure mounting plan — a flush-mount backbox anchored with drywall anchors alone won't hold this assembly safely. Structural anchor points are required.
- No battery is included. Size your standby battery against your jurisdiction's required backup duration (commonly 4 or 8 hours for access control under NFPA 730 guidance) and verify the battery fits the intended Altronix enclosure before ordering.
The EFLOW104NX8SD is the right specification for corporate office or campus access control panels running up to eight 24VDC electric strikes or mag-locks from a single power node — particularly where an integrated backup charging circuit is required and panel footprint is a constraint.
