Altronix MAXIMAL75F Access Power Controller
Overview
The Altronix MAXIMAL75F is a professional-grade access power controller engineered for security integrators and system designers requiring managed power distribution across multiple access control and auxiliary circuits. This dual-output platform consolidates 24VDC and 12VDC power delivery into a single enclosure-mounted solution, eliminating the need for separate power supplies in integrated access control systems.
The MAXIMAL75F combines two independent power supplies and chargers within a BC800 enclosure: a 24VDC supply rated at 9.7 amperes and a 12VDC supply rated at 9.5 amperes. The controller features 16 individually fused relay outputs, providing discrete switching control for door strikes, mag locks, auxiliary devices, and system supervisory circuits. Built-in FAI (Fire Alarm Interface) capability enables integration with life-safety systems, while LinQ2 Ready designation confirms compatibility with Altronix networked power management platforms for remote monitoring and control.
Key Features
- Dual Power Supply Design: Integrated 24VDC @ 9.7A and 12VDC @ 9.5A supplies eliminate external power distribution complexity
- 16 Fused Relay Outputs: Individual fusing on each relay output ensures circuit isolation and protects downstream loads from short-circuit conditions
- FAI (Fire Alarm Interface) Compatible: Supports life-safety integration for coordinated access control shutdown during fire alarm events
- LinQ2 Ready Architecture: Enables networked power management, remote monitoring, and centralized control via Altronix management platforms
- Power Supply + Charger Integration: Built-in charging capability supports connected battery backup systems for mission-critical access circuits
- BC800 Enclosure: Compact form factor designed for cabinet and wall mounting in security equipment racks and control rooms
- 115VAC Input: Standard North American utility voltage input with integrated filtering and surge protection
- Professional-Grade Reliability: Redundant output circuits support failsafe and failsecure access control topologies
Integration & Compatibility
The MAXIMAL75F serves as a central power hub for access control systems combining multiple device classes. The 24VDC output supplies electromagnetic locks, door strike actuators, and access control readers; the 12VDC output powers auxiliary sensors, notification devices, and legacy control circuits. FAI integration allows the controller to respond to fire alarm signals by removing power from access control circuits, meeting NFPA 101 Life Safety Code requirements for emergency access control shutdown.
LinQ2 Ready status means the MAXIMAL75F integrates with Altronix PowerFlow and other networked power management solutions, enabling integrators to monitor power supply status, relay state, and circuit health from remote locations without onsite visits. This capability reduces operational overhead in multi-site deployments and accelerates troubleshooting response times.

I've specified the MAXIMAL75F on access control projects where integrators needed to consolidate power delivery without adding panel footprint. The dual-output design eliminates the inventory headache of managing separate 24VDC and 12VDC supplies, and the 16 individually fused relay outputs give you flexibility to partition circuits by function — door control on one set, auxiliary sensors on another. The 9.7A at 24VDC handles four to six high-draw mag locks depending on duty cycle, which covers most mid-scale deployments.
Technical Highlights:
- Dual Output Capacity: 24VDC @ 9.7A and 12VDC @ 9.5A deliver enough current for mixed-voltage access control ecosystems without external power distribution modules
- Fused Relay Architecture: Each of the 16 outputs is individually protected, so a fault on one circuit doesn't cascade across the system
- FAI and LinQ2 Ready: Built-in fire alarm interface meets life-safety code requirements; LinQ2 compatibility future-proofs the installation for networked power monitoring without additional hardware
Deployment Considerations:
- Verify your access control readers and solenoids draw within the 9.7A 24VDC envelope; heavy-current installations may require load splitting across multiple circuits or external contactors
- Plan battery backup integration early — the integrated charger supports supervised backup power, eliminating the need for external charging modules
- Use the LinQ2 capability to establish real-time alerts on power supply faults; this catches failing supplies before they impact access availability
The MAXIMAL75F is a practical choice for integrators building modular, scalable access control systems. The fused relay design keeps troubleshooting straightforward, and the FAI integration removes compliance guesswork on life-safety coordination. If you're running mixed 24VDC and 12VDC circuits, this controller consolidates what would otherwise be two separate supply blocks into one cabinet-friendly unit.
