Altronix SMP10PM24P8 24VDC 10A 8-Output Power Supply

Altronix SMP10PM24P8 24VDC Power Supply Charger

Overview

The Altronix SMP10PM24P8 is a 24VDC regulated power supply and charger designed for distributed security and access control installations requiring multiple, independently protected output circuits. Rated at 10 amps maximum output, the SMP10PM24P8 delivers 24VDC from a 115VAC input source across eight individually fused outputs, each capable of independent load management. This architecture is essential for integrators needing to isolate circuit failures, reduce troubleshooting time, and maintain continuous operation of critical system segments. The unit is housed in an Altronix BC300 enclosure, which provides compact form factor suitable for wall or cabinet mounting in both retrofit and new construction deployments.

Key Features

• Eight Fused Outputs: Independent fusing on each output circuit prevents cascading failures and isolates faulty loads from the power distribution network
• 24VDC Nominal Output: Industry-standard voltage compatible with access controllers, electric strikes, mag locks, intercom systems, and auxiliary devices
• 10 Amp Total Capacity: Sufficient aggregate current for mid-scale distributed installations while maintaining regulated voltage under typical mixed loads
• 115VAC Input: Standard North American AC mains compatible with standard facility power infrastructure
• Supervision Capability: Built-in supervision circuit enables monitoring of power supply status and early detection of load imbalance or component degradation
• Battery Backup Ready: Integrated charger supports backup battery integration for UPS-style operation during AC mains loss, critical for access control continuity
• BC300 Enclosure: Compact, robust steel housing designed for secure mounting in electrical closets, equipment racks, or protected wall locations
• Regulated Output: Maintains stable 24VDC across the specified load range, protecting sensitive control equipment from voltage sag and surge conditions

Integration & Compatibility

The SMP10PM24P8 is widely used in access control systems where individual door controllers, credential readers, and electric locking mechanisms require protected, supervised power distribution. The eight independently fused outputs eliminate the need for external circuit protection modules when deploying modular access points across a facility. Integration with battery backup systems is straightforward—the charger circuit accommodates standard lead-acid or gel-cell batteries, enabling graceful system operation during AC interruption. Installers routinely specify this unit for door control zones, intercom power distribution, and auxiliary device circuits in commercial buildings, apartment complexes, and industrial facilities where reliable 24VDC is non-negotiable.

Package Contents

The Altronix SMP10PM24P8 ships as a complete unit within the BC300 enclosure, ready for installation. The supply includes the power supply board, fused output terminals, and mounting hardware for standard DIN rail or wall surface installation.

I've deployed the Altronix SMP10PM24P8 across multiple access control retrofits where power distribution complexity was a significant design constraint. The eight independent fused outputs are genuinely valuable—they simplify troubleshooting and eliminate single-point-of-failure risk across distributed door control zones. The BC300 enclosure keeps the installation compact and professional-looking even in tight equipment closets.

Technical Highlights:

• Independent Fusing: Each of the eight outputs is individually fused, allowing a failed load (short, overload, or component failure) to trip only its own circuit without affecting the remaining seven outputs. This is operationally superior to a single main fuse design.
• Supervision Circuit: The integrated supervision capability provides real-time feedback on supply status and output loading. Combined with a building management system or access control panel, this enables proactive alerting before user-facing failures occur.
• Battery Charger Integration: The SMP10PM24P8 is charger-equipped, so backup batteries can be integrated directly without requiring external charging modules. Critical during AC mains loss—doors remain operational and logs remain intact.

Deployment Considerations:

• Plan output circuit allocation carefully: eight outputs means eight independent zones. Map each output to a physical control point (door, reader, intercom feed) before installation to avoid mid-project reconfiguration.
• Verify backup battery size against the anticipated hold-up time. At 10A total capacity, battery sizing depends on which loads must remain active during an AC event. Typical installations use 7–12Ah batteries for 30–60 minute backup windows.
• Confirm that your access control panel or management interface supports supervision monitoring. The SMP10PM24P8 provides the telemetry; your head-end system must ingest it for the supervision investment to pay off operationally.

For integrators managing multi-door or multi-zone facilities, the SMP10PM24P8 represents a mature, reliable architecture. Eight independent circuits plus supervision and battery backup support yield a system that is resilient to component failure and transparent in its operational status. Strongly recommended for professional access control and distributed security applications.
