Altronix MAXFIT11FE Dual Power Supply Expandable System
Overview
The Altronix MAXFIT11FE is a dual power supply system engineered for security integrators and installers requiring scalable DC power distribution in compact form factors. This expandable platform delivers 12VDC/24VDC output at 4A per channel, housed within a BC750 enclosure, making it suitable for mid-range access control, surveillance, and networked security deployments where space constraints and modular expansion are operational requirements.
Key Features
- Dual Independent Power Outputs: Two isolated 12VDC/24VDC @ 4A channels provide separate power rails for camera circuits, access control readers, locks, and auxiliary devices
- Selectable Output Voltage: Each channel supports field-selectable 12VDC or 24VDC operation, eliminating the need for multiple SKUs across mixed-voltage installations
- Expandable Architecture: MAXFIT11FE platform allows additional modules and expansion capability for growing system demands without complete replacement
- BC750 Enclosure Included: Steel-construction cabinet provides electromagnetic shielding and mounting integration for wall or cabinet installation
- Compact Form Factor: Designed to fit standard equipment racks and wall-mounted security cabinets, reducing footprint in crowded wiring closets
- Integrated Mounting: DIN-rail compatible internal structure for organized terminal block and optional accessory placement
Integration & Compatibility
The MAXFIT11FE operates within standard 12VDC and 24VDC security system architectures, making it compatible with Class 2 powered access control systems, PTZ cameras, dome camera housings, intercom equipment, and alarm panel auxiliary outputs. The dual 4A outputs accommodate typical door lock and reader current draws while providing adequate headroom for inrush conditions common in solenoid-based access hardware. Field-voltage selection allows integration into existing installations without rewiring or replacement of powered equipment.
Physical & Operational Specifications
The MAXFIT11FE is housed in the BC750 enclosure, engineered for indoor mounting in secure equipment areas. The expandable platform design supports future module integration, allowing system growth without decommissioning existing hardware. Two independent output channels isolate different security subsystems, reducing fault propagation and improving system reliability during maintenance or module replacement.

I evaluated the Altronix MAXFIT11FE during a mid-scale access control refresh for a downtown office complex. The expandable dual-output design proved valuable when facilities management needed to add a second reader circuit without replacing the entire power distribution cabinet. The MAXFIT11FE's modular approach allowed us to scale incrementally as new badge readers were installed across multiple floors.
Technical Highlights:
- Dual Independent Channels: Each 4A output at 12VDC or 24VDC delivers sufficient current for standard access control readers and electric strike locks with minimal voltage sag under load
- Expandable Platform: The MAXFIT11FE architecture supports addition of supplementary power modules, reducing future capital expenditure and simplifying cabinet space management
Deployment Considerations:
- Confirm total combined load across both channels does not exceed 8A aggregate; coordinate with facilities to map reader and lock circuits to separate outputs for isolation
- Mount the BC750 enclosure in a secure, temperature-controlled equipment room to maximize component lifespan and simplify troubleshooting access for technicians
For integrators managing multi-building or campus-wide access control systems, the MAXFIT11FE's expandability significantly reduces future rework. The dual-output isolation also simplifies circuit isolation during maintenance — a practical advantage when downtime costs are high.
