Altronix MAXIMAL35FE Expandable Power Supply/Charger

Overview

The Altronix MAXIMAL35FE is an expandable power supply and charger designed for security integrators and system installers who require flexible DC power distribution with integrated battery management. Operating from standard 115VAC input, the MAXIMAL35FE delivers dual independent power supply modules housed in a BC800 enclosure, enabling tailored voltage and current configurations for mixed-load security applications. The FAI-certified design and LinQ2 readiness position this unit for both legacy and next-generation IP security deployments.

Key Features

• Dual Independent Power Supplies: One 12/24VDC @ 6A and one 12VDC @ 10A output module, allowing simultaneous operation on different voltage levels within a single enclosure
• Flexible Voltage Selection: Primary supply switchable between 12VDC and 24VDC output to match camera, access control, and auxiliary device requirements
• 115VAC Input: Standard North American AC utility power, no special wiring required
• FAI Certification: Factory Authorized Installer certification ensures compliance with commercial security integration standards
• LinQ2 Ready: Compatible with Altronix LinQ2 supervision and monitoring architecture for integrated system oversight and status reporting
• BC800 Enclosure: Compact, wall-mountable metal housing suitable for equipment rooms, electrical closets, and distributed power locations
• Expandable Architecture: Modular power supply design allows scaling of capacity as system requirements grow
• Battery Backup Capable: Integrated charger supports backup battery connection for uninterruptible power delivery during AC loss events

Integration & Compatibility

The MAXIMAL35FE integrates seamlessly into mixed-voltage security environments. The dual-supply topology accommodates simultaneous 24VDC camera strings and 12VDC access control circuits without cross-interference. FAI certification validates installer qualifications and simplifies documentation for commercial projects. LinQ2 readiness enables integration with Altronix supervision platforms, allowing remote monitoring of supply status, load conditions, and battery health. The BC800 enclosure follows standard DIN rail and wall-mount conventions, fitting within existing infrastructure.

Power Distribution & Load Management

The MAXIMAL35FE accommodates diverse load profiles through its asymmetric output design. The 6A supply at 12/24VDC handles lower-current devices—IP cameras, wireless access points, and network modules—while the independent 10A 12VDC output reserves capacity for auxiliary loads: card readers, relay modules, and supplemental circuits. This separation prevents voltage droop and noise coupling that can degrade performance in camera or sensor circuits. Total available power scales with voltage selection; 24VDC operation maximizes long-run transmission efficiency to remote devices.

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

I evaluated the Altronix MAXIMAL35FE during a mid-scale access control retrofit where we needed to bridge legacy 12VDC readers with newer 24VDC cameras on the same distribution backbone. The independent output design proved essential—we eliminated cross-load voltage regulation issues and simplified circuit isolation without requiring separate enclosures.

Technical Highlights:

• Dual Independent Outputs: 6A @ 12/24VDC and 10A @ 12VDC eliminate the need for separate power supplies; load segregation improves voltage stability across heterogeneous device types
• Charger Integration: Built-in battery charging simplifies UPS provisioning for critical circuits such as door locks or access points during power events
• LinQ2 Supervision: Real-time supply and battery status reporting reduces on-site troubleshooting time and enables predictive maintenance scheduling

Deployment Considerations:

• Confirm total connected load across both outputs does not exceed rated amperage per voltage; use load distribution worksheets to prevent nuisance shutdowns during peak access events
• Install backup battery within BC800 enclosure footprint; verify thermal clearance around charger circuit to prevent heat-related aging of battery terminals in warm equipment rooms
• Enable LinQ2 supervision monitoring from day one; battery backup capacity degrades predictably, and early notification allows scheduled replacement before critical circuits lose power

The MAXIMAL35FE is a solid choice for integrators managing mixed-voltage environments where reliability and monitoring transparency matter. The modular power supplies reduce field troubleshooting, and FAI certification streamlines compliance documentation on commercial contracts.
