Altronix MAXIMAL7 16-Output Access Power Controller
The Altronix MAXIMAL7 is a 16-output fused power distribution unit engineered to centralize power delivery across access control installations. Unlike daisy-chaining power supplies or running individual feeds to each door, the MAXIMAL7 consolidates 16 independent circuits into a single, protected enclosure. Each output is individually fused—meaning a short or fault at one door controller won't cascade and take down the entire system. For security integrators managing multi-door facilities, this isolation translates directly into faster troubleshooting and uptime.
Key Features
- 16 Independent Fused Outputs: Each channel has its own circuit protection. If a card reader or electronic lock fails short, only that output trips—the remaining 15 doors stay live. In a 10-door installation, you avoid the scenario where one failed reader cuts power to all downstream locks.
- Centralized Power Distribution: Routes power from a single supply or UPS to multiple access control devices (card readers, electric strikes, magnetic locks, request-to-exit buttons). Reduces wiring complexity and consolidates protection in one managed point rather than scattered across a facility.
- Fuse-Based Protection Architecture: Passive fused design means no active monitoring or firmware to maintain. Fuses are industry-standard replaceable components; when a circuit overloads, the fuse blows, isolation is immediate, and you swap a $2 fuse rather than troubleshooting a failed power supply or waiting for a service call.
- Compact Enclosure Form Factor: Designed to mount in standard electrical cabinets or DIN rail enclosures. Small enough to fit in a wall-mounted panel or a telco cabinet without consuming excessive real estate, but large enough to handle the physical connectors and terminal blocks needed for 16 circuits.
- Lifetime Limited Warranty: Altronix backs the unit with a lifetime limited warranty, reflecting confidence in the passive design. No active cooling, no power conversion circuitry to fail—just terminal blocks and fuses.
- Straightforward Integration: Accepts power input (typically from a 12VDC or 24VDC access control power supply) and distributes it across 16 separately protected rails. Works with any standard access control device that draws Class 2 power (under 24VDC, limited current per circuit).
Typical Deployment Scenarios
The MAXIMAL7 shines in multi-door access control environments: office parks with a dozen or more controlled doors, warehouse loading docks with multiple strike locks, or parking facilities with gate operators and card readers. It's equally at home in retrofit projects, where running individual power feeds would require extensive conduit work, and in new construction, where a single protected distribution point simplifies design and installation.
In a 16-door scenario, the alternative is either a single unprotected distribution block (loses everything if one circuit faults) or 16 separate, individually fused power supplies (higher cost, more cabinet real estate, more failure points). The MAXIMAL7 sits in the practical middle: consolidated protection without redundancy overhead.
Compatibility & Integration
The MAXIMAL7 functions as a passive power distribution hub. It is compatible with any access control system that uses low-voltage Class 2 power (typically 12VDC or 24VDC) and standard terminal block connectors. Common integrations include card access panels (Honeywell, Salto, Genetec, Axis, etc.), electronic strike locks, magnetic locks, and request-to-exit devices. Because it is purely passive (no protocol support, no active management), no special configuration or VMS integration is required—power in, 16 fused outputs, done.
When to Choose a Different Approach
If you need remote monitoring of circuit faults or real-time power-status reporting to a security management system, look for intelligent power controllers with network connectivity and reporting capabilities. If your installation requires redundant power supplies or UPS failover logic, consider a managed power distribution unit. If you have only a handful of doors or non-critical access points, individual small fused supplies at each device may be more cost-effective. The MAXIMAL7 is optimized for the case where you have multiple doors in a single location, reasonable cable runs, and a desire to simplify installation and troubleshooting through centralized, passive protection.
Frequently Asked Questions
Q: What is the maximum current per output on the MAXIMAL7?
A: Consult the datasheet for fuse ratings and per-channel current limits. Typical access control installations run 2–4 amps per circuit (covering a card reader, strike, and wiring losses), well within standard fuse ratings.
Q: Can I use the MAXIMAL7 in a cabinet with a UPS?
A: Yes. The MAXIMAL7 is a passive distribution device. Connect your UPS or battery-backed 12/24VDC supply to the input, and the 16 outputs remain protected across a power event. The fuses will still protect individual circuits if a device fails short.
Q: Is the MAXIMAL7 supervised or monitored?
A: No. The MAXIMAL7 is a passive fused distribution unit with no active monitoring, remote status, or network connectivity. Fuse status is visual only—you need to inspect the unit to confirm a fuse has blown.
Q: What enclosure type is required for the MAXIMAL7?
A: The unit is designed for standard electrical enclosures, control cabinets, or DIN rail mounting. Consult installation documentation for exact dimensional and mounting requirements.
Q: Does the MAXIMAL7 work with Altronix power supplies?
A: Yes. The MAXIMAL7 integrates with any Altronix low-voltage Class 2 power supply (PoSi, VertiLine, eFlow, etc.). It also works with third-party access control power supplies using standard 12VDC or 24VDC output and terminal block connectors.
Q: What is the warranty coverage on the MAXIMAL7?
A: The unit includes a Lifetime Limited Warranty from Altronix, covering defects in materials and workmanship under normal use.

The Altronix MAXIMAL7 does one job with discipline: it isolates faults. In access control, a shorted door reader or a wet contact at a strike can easily cascade and kill power to a whole floor's worth of doors if you're not careful. The MAXIMAL7's 16 independent fused circuits eliminate that risk. Each circuit trips independently, meaning you troubleshoot one fault without collateral damage. For integrators working on larger multi-door jobs, that isolation is a time-saver and a liability reducer.
Technical Highlights:
- 16 Independently Fused Outputs: Each circuit has its own overcurrent protection. A fault on output 1 does not affect outputs 2–16. In a 20-door facility, you avoid the scenario where a single failed reader takes the system offline.
- Passive Design with No Active Monitoring: No firmware, no network connectivity, no power conversion—just terminal blocks and fuses. Lower mean-time-to-repair because there's nothing to reset or reconfigure; swap a fuse and move on. Zero dependency on software updates or remote supervision.
- Lifetime Limited Warranty: Reflects the robustness of the passive architecture. No active cooling, no complex power conversion circuitry to degrade over time. Common failure mode is a blown fuse (expected), not a component failure.
Deployment Considerations:
- No Remote Visibility: Fuse status is visual inspection only. If you need remote alarm reporting when a circuit trips, you'll need an external monitoring relay or a managed power controller. For unmanned closets or remote locations, that's a gap.
- Passive Power Distribution Only: The MAXIMAL7 does not manage power sequencing, provide UPS supervision, or report circuit load. It distributes and protects. If you need active power management or redundancy, layer on a managed supply or controller upstream.
- Cabinet Space and Heat: Fuses generate minimal heat (passive design), but 16 independent circuits do require physical terminal block space. Ensure your enclosure is wide enough and that you have clear access to swap fuses when needed.
Position the MAXIMAL7 in any multi-door access control retrofit or new build where centralized, passive protection beats the complexity and cost of 16 separate supplies or the risk of a single unprotected distribution block. It's particularly valuable in retrofit work, where avoiding major conduit runs saves days of labor. For mission-critical environments where you need remote monitoring and failover logic, consider a managed power distribution system instead.
