Altronix SMP10PM 12/24VDC 10A Power Supply Charger
The Altronix SMP10PM is a compact, dual-voltage power supply and battery charger rated for 10A output — selectable between 12VDC and 24VDC depending on your connected equipment. Built for security infrastructure that demands continuous operation, the SMP10PM accepts 24/28VAC input and delivers regulated DC output with integrated automatic battery charging and supervision. This makes it a core power component for access control systems, alarm panels, networked security devices, and surveillance equipment requiring uninterrupted power and backup battery management.
Key Features
- Dual output voltage selection (12VDC or 24VDC): Match your system's voltage requirement without inventory complexity — set once, deploy to multiple installations if standardized.
- 10A maximum current capacity at 12VDC: Sufficient for mid-scale access control panels, alarm processors, and multiple networked devices; if you're powering six to eight IP cameras or a multi-door controller, this current budget typically works without a secondary supply, though you'll want to verify your total load.
- 24/28VAC input voltage compatibility: Works with standard secondary transformer outputs found in most security installations; accepts the typical 24VAC supplied by most commercial HVAC transformers and security power distribution panels.
- Integrated battery charger with backup capability: Automatically manages charging and floating voltage for connected backup batteries — the system continues delivering power to your devices during mains failure without manual switchover.
- Battery presence supervision: Built-in monitoring confirms a battery is connected and healthy; loss of battery signals a fault condition to your control system, preventing silent failure during an outage.
- Compact form factor — 7" × 4" × 2": Fits inside most standard security cabinets, alarm enclosures, and DIN-rail mount spaces without consuming excessive rack real estate; nestles alongside other modular power and control gear in tight installations.
- CE approval for international deployment: Meets EU electromagnetic compatibility and safety directives; reduces certification friction if you ship systems into European markets or distribute through EU channels.
- Lifetime Limited Warranty: Covers manufacturing defects for the life of the product; aligns with the typical durability of industrial power supplies if used within rated specifications.
Integration & Compatibility
The SMP10PM is a standalone power conditioning and battery management module — no software, no network connection. Wire 24/28VAC to the input terminals, connect your load to the positive and negative output terminals, and attach a sealed lead-acid or similar backup battery to the dedicated battery terminals. The unit automatically manages float charging without user intervention. Output voltage is set via a front panel selector switch before commissioning, so verify your system's voltage requirement before installation. One single output limits this unit to primary power distribution rather than multi-channel load splitting — if you need to separately supervise or control power to individual devices, you'll need additional distribution modules or relays downstream.
Frequently Asked Questions
Q: Does the SMP10PM work with any backup battery, or are there constraints?
A: The SMP10PM is rated for automatic charging and float supervision of sealed lead-acid batteries. Verify the battery's amp-hour rating and intended use case; oversizing the battery extends runtime but increases charging time. Consult the datasheet or contact the manufacturer for specific battery compatibility if using non-standard chemistries.
Q: What is the typical runtime on battery backup?
A: Runtime depends on the capacity of the connected battery and the load current draw. A 7Ah battery powering a 1A load delivers roughly 7 hours of backup; a 17Ah battery extends that to approximately 17 hours. Multiply your expected load current (in amps) by the battery capacity (in amp-hours) and divide by the load to estimate runtime.
Q: Can the SMP10PM power multiple devices in parallel?
A: Yes — the single 10A output terminal can power multiple devices in parallel, as long as the combined current draw does not exceed 10A. An access control panel consuming 3A, an alarm processor at 1.5A, and a door strike at 2A would total 6.5A, well within the supply's rating. If your combined load exceeds 10A, you'll need an additional power supply or a higher-capacity unit.
Q: Is the SMP10PM suitable for outdoor cabinet installations?
A: The SMP10PM itself is not rated IP67 or higher for direct submersion or full outdoor mounting without an enclosure. If deploying in a weatherproof cabinet or DIN-rail mount inside a sealed junction box, it will operate reliably. For fully outdoor exposed mounting, house it in a NEMA 4X enclosure or equivalent.
Q: What is the difference between 12VDC and 24VDC output selection?
A: 12VDC is common in legacy alarm systems and some access control panels; 24VDC is the modern standard for most networked security devices, IP cameras, and newer access control systems. The output voltage is set via a selector switch during initial setup. Choose based on your equipment's input rating — mixing voltages requires downstream conversion and adds cost and potential loss.

The Altronix SMP10PM is a purpose-built power distribution and battery management module for security installations that cannot tolerate mains-supply gaps. The 10A capacity and integrated charger eliminate the need to wire a separate battery charger into the cabinet, reducing component count and installation labor. The dual-voltage output (12VDC/24VDC) also simplifies spares inventory if you're managing multiple sites with mixed legacy and modern equipment.
Technical Highlights:
- 10A @ 12VDC output rating: Supports a mid-tier access control panel (3–4A), alarm processor (1.5–2A), and two solenoid strikes or readers (2–3A combined) without a secondary supply — straightforward load planning for typical two- to four-door installations.
- Integrated float charger with battery supervision: Automatically maintains the backup battery in standby and signals a fault if the battery is missing or failed — no separate charger module or manual monitoring required.
- 24/28VAC input acceptance: Compatible with the standard secondary voltage from most commercial security transformers and legacy building HVAC systems — minimal wiring re-qualification in retrofit scenarios.
Deployment Considerations:
- Single output terminal = no load isolation: All downstream devices share the same supply rail; a fault or overcurrent in one device affects the entire system unless you add fused distribution blocks or relays downstream.
- Verify battery chemistry before installation: The charger is optimized for sealed lead-acid; lithium or AGM batteries may require different float voltages — confirm compatibility with the manufacturer before swap-out.
- Cabinet thermal management: The SMP10PM generates heat during heavy loads and charging cycles; if installed in a sealed cabinet with limited airflow, monitor internal temperature or add a small ventilation fan to prevent thermal shutdown.
Position the SMP10PM as the backbone power module for small to mid-size access control and alarm panel deployments where mains backup is critical and cabinet space is limited. It's a workhorse accessory, not a design centerpiece — specify it when you have confirmed load budgets and voltage requirements, and pair it with appropriately rated backup batteries and load distribution modules downstream.
