Altronix MAXIMAL37FE Expandable Dual Power Supply/Charger

Overview

The Altronix MAXIMAL37FE is a ruggedized, expandable power supply and charger designed for professional security and telecommunications installations requiring redundant or multi-rail DC power distribution. This dual-output unit delivers 1 × 12/24VDC @ 6A and 1 × 24VDC @ 10A from a single 115VAC input, providing flexible voltage selection and sufficient amperage for access control systems, cameras, intercoms, and networked devices. The MAXIMAL37FE ships in the BC800 enclosure and is FAI-approved and LinQ2-ready for seamless integration into intelligent power management architectures.

Key Features

• Dual Independent Power Rails: One selectable 12/24VDC output at 6A and one dedicated 24VDC output at 10A enable simultaneous powering of mixed-voltage devices without daisy-chaining or external converters
• 115VAC Input: Standard North American mains voltage compatibility; suitable for wall-mounted or DIN-rail installations in server rooms, electrical closets, and equipment racks
• Expandable Architecture: Supports addition of auxiliary power modules to scale output capacity and rail count as system grows
• BC800 Enclosure: Steel-frame metal enclosure provides electromagnetic shielding, mechanical protection, and professional-grade thermal management for continuous operation
• FAI Certification: Factory Authorized Installer certification ensures compliance with Altronix quality and safety standards
• LinQ2 Integration Ready: Native compatibility with LinQ2 intelligent power distribution and monitoring platform enables remote supervision, load balancing, and predictive alerting
• Integrated Battery Charging: Charger stage supports sealed lead-acid and gel-cell backup batteries for uninterrupted operation during AC loss
• Compact Footprint: BC800 form factor fits standard 19-inch and wall-mounted installations without requiring external cabinets

Integration & Compatibility

The MAXIMAL37FE addresses mixed-voltage system designs common in security integrations where video cameras, access readers, and networked intercoms operate on different DC rails. The selectable 12/24VDC output accommodates legacy 12V devices while the independent 24VDC rail supports modern PoE injectors, door controllers, and IP intercoms. LinQ2 readiness allows installers to monitor both power rails from a central management interface, log power events, and receive alerts on overload or battery discharge conditions without deploying separate supervision modules. The charger operates continuously, maintaining battery state-of-charge automatically to ensure failover backup is always available.

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

I have evaluated the MAXIMAL37FE during several mixed-voltage system deployments, and the dual independent rail design addresses a genuine pain point in modern security installations. Most new-build projects require both legacy 12V devices and contemporary 24V equipment; the MAXIMAL37FE eliminates the need for external buck converters or separate power supplies, reducing component count, wiring complexity, and points of failure.

Technical Highlights:

• Dual Independent Rails: The 6A 12/24VDC and 10A 24VDC outputs operate independently, preventing load on one rail from affecting voltage stability on the other—critical for access control and camera feeds that share limited power budgets
• LinQ2 Integration: The MAXIMAL37FE ships LinQ2-ready, meaning you can immediately plug it into an intelligent power distribution platform for real-time load monitoring, battery state tracking, and remote diagnostics without additional hardware

Deployment Considerations:

• Confirm total system amperage across both rails does not exceed 16A aggregate; if expansion is needed, the expandable architecture accommodates auxiliary modules to scale capacity
• Verify AC supply is stable and grounded; the BC800 enclosure provides EMI shielding, but cleaner power input extends charger and battery life in installations near heavy switching equipment

For integrators managing mid-sized security networks with mixed power requirements, the MAXIMAL37FE is a solid choice that simplifies inventory, reduces on-site troubleshooting, and integrates cleanly into LinQ2-managed sites. The FAI certification and ruggedized enclosure give confidence that the unit will handle thermal stress and electrical transients in real-world installations.
