Altronix MAXIMAL77FE Expandable Dual 24VDC Power Supply/Charger
Overview
The Altronix MAXIMAL77FE is a professional-grade power supply and charger engineered for distributed security systems, access control installations, and integrated communication networks. This unit delivers two isolated 24VDC outputs at 9.7A each, providing dedicated power paths for independent loads or redundant circuit protection. Operating from 115VAC input, the MAXIMAL77FE integrates battery charging capability and is designed to expand within system architectures that demand scalability and voltage isolation. The unit ships with BC800 enclosure packaging for DIN rail or wall-mount deployment scenarios common in security integrator environments.
Key Features
- Dual 24VDC Outputs: Two isolated 24VDC circuits each rated at 9.7A, enabling independent load control and circuit separation for enhanced system reliability
- 115VAC Input Voltage: Standard North American mains compatibility for straightforward retrofit and new installation scenarios
- Expandable Architecture: Supports field expansion and modular configuration growth for multi-building or campus-wide deployments
- Battery Charging Integration: Built-in charging capability for UPS backup systems and battery-dependent failover circuits
- FAI Compatible: Meets Fire Alarm Industry standards for integration into supervised fire alarm and life safety networks
- LinQ2 Ready: Prepared for Altronix LinQ2 monitoring and status reporting protocols, enabling remote diagnostics and fault notification without additional gateway hardware
- BC800 Enclosure: Compact DIN-rail mountable form factor designed for secure indoor cabinet installations and equipment room deployments
- Isolated Output Circuits: Each 24VDC rail operates independently, allowing separate device strings or redundant power paths without crosstalk or voltage sag coupling
Integration & Compatibility
The MAXIMAL77FE is engineered for security integrators deploying access control, CCTV power distribution, intercom systems, and emergency communication networks. Its dual isolated outputs accommodate configurations where different subsystems require independent voltage regulation—such as powering door locks on one circuit and cameras on the second, with full electrical isolation between them. FAI compliance ensures the unit can be specified for fire alarm auxiliary power applications. LinQ2 readiness means system status, output voltage, and fault conditions can be monitored through Altronix control platforms, reducing on-site troubleshooting time and supporting predictive maintenance workflows. The 115VAC input accepts standard North American utility feeds and battery charger circuits, making field integration straightforward in retrofit scenarios.
Battery Backup & Reliability
The integrated charger supports external backup battery banks for extended runtime during AC power loss. This capability is critical in access control and emergency communication applications where power interruption cannot be tolerated. Dual isolated outputs ensure that if one load circuit experiences a fault, the second remains powered and unaffected—a topology preferred in life safety and redundant system designs.

I've reviewed the MAXIMAL77FE during integration planning for a multi-site access control rollout. The dual 24VDC outputs at 9.7A each provide the voltage isolation and current capacity needed to power independent lock circuits and card readers without voltage sag or interaction between loads. The FAI listing is a practical requirement when integrating with supervised systems, and LinQ2 readiness simplifies remote monitoring without adding separate management gateways.
Technical Highlights:
- Isolated Dual Outputs: Two independent 24VDC 9.7A circuits prevent load-induced voltage sag on critical circuits and enable redundancy patterns used in enterprise access control
- Battery Charger Built-in: Supports UPS backup configurations for uninterrupted operation during AC mains failure, essential for life safety and access continuity
- LinQ2 Integration: Remote status monitoring and fault reporting without proprietary gateways reduces commissioning overhead and supports 24/7 system visibility
Deployment Considerations:
- Plan for external backup battery sizing based on load current and runtime requirement; the MAXIMAL77FE charger supports field configuration but does not include integrated batteries
- Verify DIN rail or panel space within the BC800 enclosure before installation; confirm that both output circuits will be fully utilized to justify the dual-output topology
The MAXIMAL77FE is a reliable choice for integrators who need voltage isolation, scalability, and battery backup capability in a compact, standards-compliant package. Its dual outputs and FAI compliance make it suitable for access control, emergency systems, and distributed security architectures where power redundancy is non-negotiable.
