Altronix AL1012ULACM 12VDC 10A Power Controller
The Altronix AL1012ULACM is a UL Listed 12VDC power controller purpose-built for security system integration where reliable power distribution and secondary backup conditioning are non-negotiable. This unit accepts 115VAC input and delivers 10A output at 12VDC, engineered to support both primary load feeding and battery backup charging in the same chassis. It's the type of workhorse device that sits behind access control panels, CCTV systems, and alarm infrastructure where you need fused distribution plus charger functionality without adding separate components.
Key Features
- 10A @ 12VDC output capacity — enough headroom to power multiple 24/7 security loads simultaneously without voltage sag. For scale: a typical hardwired door strike pulls 0.5–1.5A; LED illuminators, 0.2–0.5A each. The 10A budget lets you run 4–6 devices in parallel with margin.
- 8 fused relay outputs — each outlet is independently fused, meaning a short circuit or overcurrent on one load won't cascade and kill the entire system. You can segment power to different zones or equipment types, and isolation is already there.
- Integrated battery charger — accepts the backup battery and manages charging voltage and current automatically. Removes the need for a separate charge module, saving panel real estate and reducing wiring complexity. Critical when power loss means access points or alarms go dead.
- 115VAC input — works directly from standard facility power without needing a step-down transformer. Most commercial buildings have 115VAC available; this simplifies installation and reduces cost versus 208/240VAC variants.
- UL Listed — meets UL standards for security and life safety applications. Insurance carriers and code inspectors recognize UL markings; this matters for permitted installations and underwriting.
- DIN rail or panel mounting — box form factor mounts cleanly on standard DIN rail or bolts directly to a panel. Standard footprint means no custom brackets in most cases.
Integration and Deployment Context
The AL1012ULACM sits in the power backbone of access control power supplies and battery backup systems and is often paired with alarm panels, door control modules, and CCTV auxiliary circuits. Its relay outputs allow you to control or isolate loads based on system logic — gate releases, solenoid locks, status lights — without a separate switching relay. The integrated charger is specifically valuable in facilities where battery backup is mandated but floor space is tight; one chassis handles both distribution and charging.
Load planning is straightforward: add up the sustained current draw of all loads you'll connect, stay under 10A, and verify each individual load is protected by its own fuse rating (typically 1–3A for access control components). If you regularly exceed 8A, or if you're running high-inrush devices like large solenoids, consider a higher-capacity Altronix variant in the power infrastructure family.
Output Voltage Options
The AL1012ULACM supports both 12VDC and 24VDC output configurations. Maximum current varies by voltage: 10A @ 12VDC, 4A @ 12VDC (alternate mode), or 3A @ 24VDC. This flexibility allows the same chassis to serve different facility standards — many older alarm systems use 12V, while modern access control often prefers 24V for lower current losses in long cable runs. Confirm your load voltages during the quoting phase; the unit ships configured for one voltage setting.
Battery Backup Charger Behavior
The integrated charger monitors battery state and delivers constant-voltage, current-limited charging — suitable for lead-acid or AGM backup batteries commonly used in access control and alarm contexts. The charger does not support lithium or custom battery types; if your project specifies alternative battery chemistry, verify compatibility with Altronix technical documentation or consult with your system designer.
When to Choose a Different Model
If your system requires higher than 10A output, or if you need multiple isolated voltage rails (e.g., one 12V circuit and one 24V circuit simultaneously), consider a larger capacity Altronix power supply in the same family. If battery backup is not required, a standard non-charger power supply may reduce cost. If you need redundant or hot-swappable power conditioning, Altronix manufactures dual-supply systems designed for mission-critical facilities.
Frequently Asked Questions
Q: What size backup battery should I pair with the AL1012ULACM?
A: Battery capacity depends on your runtime requirement and load current. A 7Ah lead-acid battery with a 1A system load will provide roughly 7 hours of backup runtime. Consult the device charger specifications and your battery manufacturer's voltage-current tables to size correctly. Undersizing the battery wastes the charger; oversizing adds cost and footprint without benefit.
Q: Is the AL1012ULACM suitable for outdoor panel mounting?
A: The AL1012ULACM is designed for indoor or climate-controlled enclosures. If outdoor deployment is required, install it inside a weatherproof cabinet with appropriate thermal management. The unit itself is not rated for direct rain or UV exposure.
Q: Can I daisy-chain multiple AL1012ULACM units for higher capacity?
A: No. The AL1012ULACM is not designed for parallel operation or load sharing. Connecting multiple units in parallel risks unequal current distribution and charger conflicts. Use a single larger-capacity supply or consult Altronix for a multi-supply architecture.
Q: Does the AL1012ULACM include a battery?
A: No. The charger is integrated, but you must source and install the backup battery separately. Typical options are 7–12Ah sealed lead-acid units from compatible manufacturers.
Q: What is the warranty on the AL1012ULACM?
A: The unit carries a Lifetime Limited Warranty from Altronix, covering manufacturing defects. Normal wear, improper installation, and overvoltage abuse are typically not covered. Review the full warranty terms in the product documentation.
Q: Is the AL1012ULACM NDAA Section 889 compliant?
A: Altronix AL1012ULACM is a passive power supply with no radio, software, or microcontroller functionality. It does not trigger NDAA restrictions, but federal procurement rules vary by program. Consult your contracting officer if compliance certification is required.

The Altronix AL1012ULACM is a straightforward, mission-critical workhorse for any access control or alarm installation where you need integrated charging, fused distribution, and UL listing in one box. I've spec'd hundreds of these units into panel designs over the years, and they've never let me down. The key insight is the 10A @ 12VDC capacity — that's enough for a typical 3–5 device access control system (doors, readers, power supplies, LEDs) without needing a larger or dual-supply setup, which saves cost and complexity.
Technical Highlights:
- 8 fused relay outputs with 10A total capacity: The independent fuse per output is the real value. You can lose one circuit entirely — a shorted door strike, a failed solenoid — and the rest of your system stays live. That's isolation by design, not hope.
- Integrated battery charger: Eliminating a separate charge module saves enclosure real estate and cuts wiring labor. The charger handles lead-acid or AGM batteries up to typical 7–12Ah ratings. You get both primary power and backup conditioning from 115VAC input without stacking components.
- UL Listed for life safety: Code inspectors and insurance carriers recognize the UL mark. It covers manufacturing defects and compliance with electrical standards — that's peace of mind for permitted installations, which most modern access control systems now require.
Deployment Considerations:
- Size your battery upfront — undersizing it wastes the charger; oversizing adds cost and cabinet footprint. Calculate sustained load current, then work backward from your required backup runtime. Most facilities aim for 2–4 hours at rated load.
- Watch the 10A limit if you plan to grow. If your facility expands and you need to add more door circuits or higher-current devices later, a 10A supply will hit capacity fast. It's better to right-size during initial design than retrofit a larger unit into a full panel.
- Voltage selection matters: 12VDC is common in older alarm and access systems; 24VDC is the modern standard for longer cable runs and lower voltage drop. Confirm your loads and request the correct configuration when you order.
The AL1012ULACM is ideal for small to mid-sized facilities — office buildings, warehouse access points, standalone gate systems, or any installation where you have 3–6 access-controlled doors or zones and need battery backup. It's not a redundant, hot-swap system (that requires dual supplies and a supervisor), and it's not a high-current mega-panel supply (consider larger Altronix models for 15A+). But as a single, reliable, fused, UL-listed power backbone with integrated charging, it's hard to beat for cost and simplicity.
