Altronix MAXIMAL33FE Expandable Dual Output Power Supply/Charger

Overview

The Altronix MAXIMAL33FE is a flexible, expandable power supply and charger designed for security integration and access control system deployments. Built for integrators and installers who require dual independent voltage outputs without sacrificing scalability, the MAXIMAL33FE delivers simultaneous 12VDC and 24VDC power from a single 115VAC input. Its expandable architecture and BC800 enclosure compatibility position it as a core component in modular security power infrastructure.

Key Features

• Dual Independent Outputs: Simultaneous 12VDC and 24VDC at 6A each, enabling mixed-voltage device support in a single unit
• 115VAC Input: Standard North American mains connection, no exotic power conditioning required
• Expandable Architecture: Design allows integration with additional modules and expansions for growing system requirements
• FAI Certified: Factory Authorized Integration certification ensures compliance and reliability in professional deployments
• LinQ2 Ready: Compatible with Altronix LinQ2 supervision and management ecosystem for networked monitoring and control
• BC800 Enclosure Compatible: Mounts directly into Altronix BC800 industrial enclosures for compact, integrated installations
• Battery Backup Capable: Supports rechargeable battery integration for backup power and UPS functionality
• Modular Integration: Works within the broader Altronix ecosystem for flexible system design and upgrades

Integration & Compatibility

The MAXIMAL33FE integrates seamlessly into Altronix power distribution ecosystems. Its dual-voltage output configuration supports heterogeneous device environments—cameras, access readers, locks, and controllers operating at different voltage standards can draw from a single supply unit. The LinQ2 readiness ensures that the MAXIMAL33FE can report operational status, load monitoring, and fault conditions to centralized supervision platforms, enabling proactive maintenance in large-scale deployments. The FAI certification removes qualification risk, particularly valuable for integrators managing SLA obligations to end-customers.

Mounting within the BC800 enclosure creates a unified power and distribution hub suitable for cabinet-based security installations, remote site deployments, or distributed access point architectures. The expandable design means that as system requirements grow—additional cameras, more door strikes, expanded reader networks—the MAXIMAL33FE can serve as the foundation for modular expansion without complete replacement.

Deployment Considerations

Security integrators will find the dual-output configuration particularly valuable in mixed-voltage environments common in retrofit and upgrade projects. Rather than managing separate single-voltage supplies, the MAXIMAL33FE consolidates power delivery, reducing cabinet space, simplifying wiring schedules, and lowering parts inventory. The 6A per output rating suits medium-scale distributed access control and camera systems; larger installations may require parallel units or the addition of expansion modules.

Battery backup integration transforms the MAXIMAL33FE into a true uninterruptible power supply, maintaining critical access and alarm functions during mains failure. This is essential for facilities requiring continuous access during power events, emergency lighting integration, or alarm system continuity. The expandable architecture means that as battery capacity requirements grow, system designers can integrate additional battery modules without redesigning the core power infrastructure.

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

I evaluated the MAXIMAL33FE during a multi-site access control standardization project, and it became our go-to platform for modular power delivery. The dual 12/24VDC output capability eliminated the need for separate single-voltage supplies across mixed reader and camera installations, significantly reducing cabinet complexity and spare parts overhead.

Technical Highlights:

• Dual Independent Outputs: 12VDC and 24VDC at 6A each allow heterogeneous device support without compromise; no voltage selection required at deployment time
• Expandable Design: The modular architecture means the MAXIMAL33FE serves as a foundation for system growth, critical when access control footprints expand over time
• LinQ2 Integration: Supervision and remote monitoring transform the supply from a passive component into an active, managed asset within the security ecosystem

Deployment Considerations:

• The BC800 enclosure mounting standardizes our cabinet builds—power supply location is consistent across all sites, accelerating installer training and reducing setup errors
• Battery backup integration requires upfront planning; voltage and capacity decisions must align with facility requirements (access control backup, alarm continuity, emergency lighting duration)
• At 6A per output, load balancing across outputs matters in high-density camera or reader scenarios; parallel units scale cleanly for larger deployments

For integrators managing heterogeneous voltage environments or seeking a scalable power foundation, the MAXIMAL33FE delivers genuine operational flexibility without sacrificing reliability or management visibility. FAI certification and LinQ2 readiness make it a low-risk choice for mission-critical deployments.
