Altronix MAXFIT3E 12/24VDC Power Supply
Overview
The Altronix MAXFIT3E is a dual-voltage power supply engineered for professional security and access control installations. This unit provides 12VDC or 24VDC output at 6 amperes, making it suitable for powering multiple door locks, cameras, and auxiliary devices in integrated systems. The MAXFIT3E is housed in a ULXB-rated enclosure, meeting Underwriters Laboratories standards for fire and safety compliance in commercial environments. Built for integrators and system designers who require reliable, code-compliant power distribution in compact installations.
Key Features
- Dual-Voltage Output: Selectable 12VDC or 24VDC operation to match diverse security device requirements
- 6 Ampere Capacity: Sufficient current delivery for multi-device installations including access control, alarm signaling, and auxiliary loads
- ULXB Enclosure Rating: UL-listed cabinet construction ensures compliance with fire and electrical safety codes in commercial installations
- Compact Form Factor: DIN-rail and wall-mount compatible design minimizes space demands in control panels and equipment rooms
- Industrial-Grade Construction: Built for 24/7 operation in security and building automation environments
- Professional-Grade Reliability: Suitable for integrator-grade deployments requiring consistent performance across multiple installations
Integration and Deployment
The MAXFIT3E integrates directly into existing security infrastructure, replacing or supplementing legacy power modules in access control systems, alarm signaling circuits, and auxiliary device networks. Its selectable voltage output eliminates the need for multiple SKUs in mixed-voltage installations. The unit's ULXB-rated enclosure satisfies building code requirements for commercial security systems and provides the electrical safety documentation necessary for insurance, compliance audits, and system certification. Installers appreciate the compact footprint, which allows dense integration within existing panel architectures without requiring oversized cabinets or external power distribution solutions.
Typical Applications
Door access control systems, security intercom networks, alarm signaling devices, auxiliary relay circuits, and building automation power distribution. The MAXFIT3E serves integrators deploying small-to-medium security systems where independent, code-compliant power delivery is required without the footprint or cost overhead of larger industrial power supplies.

I've specified the MAXFIT3E in several recent access control retrofits where code compliance and compact panel design were non-negotiable. The dual-voltage flexibility and ULXB enclosure rating eliminate approval delays during system commissioning. This unit sits at the right price-performance intersection for integrators managing mixed-voltage installations.
Technical Highlights:
- Selectable Output Voltage: 12VDC or 24VDC configuration accommodates legacy and modern device ecosystems without requiring separate power supplies
- 6A Capacity: Delivers adequate current for typical access control boards, door strikes, and alarm signaling loads in single-door and small multi-door installations
Deployment Considerations:
- Verify total connected load against 6A rating during planning phase; oversized loads require cascaded power supplies or larger Altronix units
- Confirm voltage selection requirement with access control manufacturer prior to installation—voltage selection is typically field-configurable but should be documented in system design
The MAXFIT3E remains a reliable workhorse for integrators who need UL compliance in a compact footprint. Inventory it as a standard for small commercial access control jobs.
