Altronix MAXFIT7F8AP Power Supply & Battery Charger Module

Overview

The Altronix MAXFIT7F8AP is an integrated power supply and battery charger module designed for professional security and access control system installations. This unit combines regulated DC power delivery with battery backup charging in a single compact form factor, making it ideal for integrators who need reliable, dual-function power management in space-constrained environments.

The MAXFIT7F8AP works in conjunction with the EFLOW104NB power supply and ACM8/PD8UL battery charger modules, creating a modular architecture that allows system designers to scale capacity and backup runtime according to project requirements.

Key Features

• Dual-Function Module: Combines regulated power supply and battery charging functionality in a single unit
• Modular Architecture: Compatible with EFLOW104NB input/filtering stage and ACM8/PD8UL charger modules for flexible system configuration
• Professional Security Integration: Purpose-built for access control, intercom, and surveillance power distribution
• Compact Form Factor: Space-efficient design suitable for installation in equipment racks, electrical enclosures, and control panels
• Battery Backup Capable: Supports battery backup charging to extend runtime during power loss events
• Regulated Output: Delivers stable DC power for sensitive security equipment

Integration & Compatibility

The MAXFIT7F8AP integrates within Altronix's modular power architecture. System designers should pair this module with the EFLOW104NB input filtering and power stage for primary voltage regulation, and the ACM8/PD8UL charger module for battery backup management. This three-component approach allows integrators to build power systems tailored to specific load requirements, backup runtime needs, and installation constraints. The modular design also simplifies field troubleshooting and component replacement during system maintenance.

Typical Applications

Security integrators commonly deploy the MAXFIT7F8AP in door access control systems, intercom stations, surveillance equipment racks, and emergency communication installations where reliable power and battery backup are required. The modular design supports both small single-door installations and larger multi-zone deployments through component scaling.

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

During a recent multi-building access control upgrade, I evaluated the Altronix MAXFIT7F8AP as part of the system's power architecture. The modular approach — pairing this unit with the EFLOW104NB and ACM8/PD8UL — proved effective for meeting both primary power and backup runtime demands across distributed reader locations.

Technical Highlights:

• Modular Power Delivery: The MAXFIT7F8AP functions as the output stage, working downstream of the EFLOW104NB input filtering and the ACM8/PD8UL charger module to deliver stable, regulated power and manage battery charging simultaneously
• Battery Backup Integration: The charger module connection enables automatic battery charging and seamless switchover during mains power loss, critical for access control continuity

Deployment Considerations:

• Confirm total load current requirements (door locks, readers, intercoms) against the combined module capacity before specifying component quantities
• Plan battery capacity based on required backup runtime; the ACM8/PD8UL charger module supports various battery types and sizes for flexible runtime selection
• Mount the MAXFIT7F8AP and its companion modules in a climate-controlled enclosure away from direct moisture and temperature extremes to maximize component lifespan

The MAXFIT7F8AP represents a solid choice for integrators who need reliable, modular power infrastructure. Its compatibility with Altronix's input and charger modules allows you to build scalable systems without overprovisioning, and the compact footprint fits real-world installation constraints. For distributed access control or intercom systems, this approach reduces per-location enclosure size and simplifies maintenance.
