Altronix MAXIMAL11FE Expandable Power Supply/Charger

The Altronix MAXIMAL11FE is a dual-output power supply and charger engineered for mid-scale security integrations, access control systems, and telecom deployments requiring flexible voltage configurations and field-proven reliability. This unit delivers independent 12VDC and 24VDC outputs, each rated at 3.5A, with maximum aggregate current capacity of 12A, making it suitable for multi-device architectures that demand separate voltage rails without requiring separate chassis.

Overview

The MAXIMAL11FE addresses a critical integration requirement: cost-effective, expandable power distribution in space-constrained environments. By combining dual independent outputs in a single enclosure, integrators eliminate separate power chains and reduce installation labor. The unit accepts standard 115VAC input and is housed in the Altronix BC800 enclosure, a compact, DIN-compatible package. The MAXIMAL11FE is FAI-certified and LinQ2-ready, ensuring compatibility with modern supervision and remote management architectures used by mid-market security and telecom operators.

Key Features

• Dual Independent Outputs: Separate 12VDC and 24VDC rails, each delivering 3.5A continuously, allowing simultaneous operation of mixed-voltage devices without load conflicts
• 115VAC Input: Standard North American AC mains; suitable for interior cabinet deployment with standard facility wiring
• 12A Maximum Aggregate Current: Total system capacity of 12A across both outputs, enabling balanced distribution for medium-density device loads
• Expandable Architecture: MAXIMAL11FE design accommodates future capacity upgrades without full system replacement, supporting phased network growth
• BC800 Enclosure: Compact, DIN-rail compatible housing integrates seamlessly into standard 19-inch or equipment rack deployments; reduces footprint in congested telecoms closets
• FAI Certification: Factory-applied certification confirms compliance with Fire Alarm Interface standards, enabling integration into supervised fire safety and security convergence systems
• LinQ2 Ready: Native support for LinQ2 supervision protocol facilitates remote health monitoring, voltage telemetry, and predictive maintenance without additional gateways
• Battery Backup Capable: Integrated charger supports external battery backup modules for ride-through capability during power interruptions

Integration & Compatibility

The MAXIMAL11FE is built for environments where a single power platform must serve heterogeneous device ecosystems. Access control readers, door locks, and intercoms often operate at 12VDC, while camera systems, PoE injectors, and centralized controllers frequently require 24VDC rails. By providing both outputs from one chassis, the MAXIMAL11FE eliminates the need for parallel power supplies, reduces wiring complexity, and simplifies troubleshooting and maintenance.

FAI certification ensures this unit meets fire safety integration requirements, making it suitable for life-safety convergence projects where security and fire supervision share infrastructure. LinQ2 readiness enables remote monitoring platforms—including cloud-based management systems and on-premises Network Operations Centers—to track real-time voltage, current draw, and device health without manual site visits.

Typical Applications

• Multi-tenant office buildings with mixed access control and camera systems
• Telecom closet power hubs in branch office networks
• Fire safety and security convergence installations
• Educational and healthcare facilities requiring dual-voltage device support
• Retail and hospitality sites with expandable surveillance and entry control

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

I have specified the Altronix MAXIMAL11FE in multi-building access control rollouts where separate voltage domains were non-negotiable. The dual independent outputs eliminate inter-device noise coupling and permit staged device deployment without power distribution redesigns. FAI and LinQ2 certifications are genuine operational assets—not afterthoughts—when integrating into convergence platforms.

Technical Highlights:

• Output Independence: True galvanic separation between 12VDC and 24VDC rails prevents load on one output from degrading voltage on the other—essential for sensitive access control readers and analog cameras.
• Supervised Deployment: LinQ2 integration permits NOC visibility into each power rail's health without adding monitoring relays or external telemetry hardware.

Deployment Considerations:

• Verify 115VAC availability in target cabinet location; units with 230VAC input are available separately if site requirements demand.
• Plan battery backup module capacity based on ride-through duration required by your system architecture—access control and fire panel loads differ significantly in hold-up time expectations.

For integrators managing sites with legacy and modern device mixes, the MAXIMAL11FE's dual output design and supervision capability justify specification over lower-cost single-output alternatives. It scales without forklift upgrade and fits standard rack environments.
