Altronix AL1012ULXPD16CB 16-Output 12VDC Power Supply
The Altronix AL1012ULXPD16CB is a 16-output regulated power supply engineered for distributed power delivery across multi-device security installations. Operating from standard 115VAC input, it delivers up to 10A total current across 16 individually fused outputs — meaning each output is isolated, so a short or fault on one channel won't cascade to others. This architecture is critical when powering door controllers, magnetic locks, and cameras from a single centralized location; the fusing prevents a single device failure from taking down your entire access control or surveillance network.
Key Features
- 16 independent fused outputs: Each output is individually protected, so a short circuit or overload on one device won't affect the remaining 15 channels. In a warehouse or multi-door access control deployment, this means you isolate failures instead of losing power to critical zones.
- 12VDC regulated output: Voltage regulation ensures stable, consistent power delivery across all 16 channels, preventing brownout conditions that can cause access control lockups or camera resets during peak load periods.
- 10A maximum current capacity: Total system draw across all 16 outputs is capped at 10A — approximately 625mA per output if load is distributed evenly. Sufficient for door strikes (typically 300–600mA each), proximity readers, auxiliary alarm modules, and low-power camera supplies; confirm actual device draw before oversizing or daisy-chaining.
- 115VAC input accepts standard North American utility power: No DC converter or separate rectifier needed — plug directly into wall outlet or UPS, reducing installation complexity and eliminating an extra component in the power chain.
- Terminal block field wiring: Screw-down connectors allow fast, field-friendly installation without crimped connectors or soldering; simplifies troubleshooting and future modifications.
- Compact form factor: Sized for wall or rack mounting in electrical closets and equipment rooms where space is tight; particularly useful in retrofit access control upgrades where you cannot dedicate an entire cabinet.
- Lifetime Limited Warranty: Coverage for manufacturing defects and component failures — typical for Altronix power infrastructure, reducing long-term replacement risk in deployed systems.
Integration & Compatibility
The AL1012ULXPD16CB integrates into any security architecture requiring distributed 12VDC power. Common applications include access control systems powering Honeywell, HID, Salto, or Kisi door controllers and electric strikes; power supplies for networked cameras that require auxiliary 12VDC rails; alarm system zone modules and repeaters; and intercom amplifiers. Pair with a UPS or backup battery to maintain access control and alarm signaling during mains power loss. For larger multi-building campuses, cascade multiple AL1012ULXPD16CB units across different zones, managing each via separate circuit breakers to avoid single-point failures.
When to Choose a Different Model
If you require higher current capacity (e.g., more than 10A total, or more than ~625mA per channel), consider a higher-capacity variant within the Altronix power family. If your devices operate at 24VDC rather than 12VDC, select a 24VDC-output model. If battery backup is a requirement, integrate the AL1012ULXPD16CB with a separate UPS or battery backup system rather than relying on this supply alone during power loss.
Frequently Asked Questions
Q: Can I use the AL1012ULXPD16CB to power IP cameras directly?
A: Not directly. Most IP cameras operate at 12VDC PoE or 48VDC PoE. The AL1012ULXPD16CB supplies raw 12VDC, which is suitable for camera power supplies or auxiliary 12VDC accessories, but not as a primary PoE injector. Confirm your camera's input specification before connection.
Q: What happens if one output exceeds its share of the 10A total?
A: Each output is fused individually. If one channel draws more than its fuse rating, that fuse will open and cut power to that output only. The remaining 15 outputs continue to operate. You'll need to replace the fuse and identify why that device overdrawn (short circuit, failed component, or undersized device). Check the datasheet for fuse ratings per channel.
Q: Is the AL1012ULXPD16CB UPS-compatible?
A: Yes, it accepts 115VAC input, so you can plug it into a UPS outlet. During power loss, the UPS supplies AC to the AL1012ULXPD16CB, which then continues to deliver 12VDC to your access control and alarm devices. Plan for backup runtime based on UPS capacity and the security system's actual draw.
Q: Can I upgrade or parallel two AL1012ULXPD16CB units?
A: Paralleling two supplies is not recommended without load-sharing circuitry — the outputs may not split current evenly, risking overload on one unit. For higher capacity, consult Altronix's higher-amperage models or deploy separate supplies to different zones with independent circuit protection.
Q: What warranty coverage does the AL1012ULXPD16CB include?
A: Lifetime Limited Warranty covers manufacturing defects and component failures. Review the full warranty terms (available in the manufacturer's documentation) to confirm coverage scope and exclusions.
Q: Is 12VDC regulated voltage sensitive to input AC fluctuations?
A: The AL1012ULXPD16CB features regulated output, meaning it maintains 12VDC within a specified tolerance (±5% is typical for industrial supplies) across the specified input voltage range. Minor AC line sag or surge is compensated by the internal regulator, protecting your devices from voltage droop during peak building loads.

The Altronix AL1012ULXPD16CB is a workhorse for mid-scale access control and alarm deployments where you need centralized, isolated power to 16 devices on a single 115VAC circuit. Its individually fused outputs are the real differentiator — they force failures to stay local, not cascade, which matters when you're managing dozens of door strikes and controllers across a warehouse or office campus.
Technical Highlights:
- 10A total capacity, 16 independent channels: Works out to roughly 625mA average per output if fully loaded. Door strikes typically draw 300–600mA, so a single AL1012ULXPD16CB can power 12–16 strikes comfortably, with headroom for readers and solenoid locks. Actual draw depends on duty cycle — a strike that holds continuously draws more than one that pulses briefly on unlock.
- Individual fusing per output: If a reader short-circuits on channel 3, it blows only that fuse. Channels 1–2 and 4–16 keep running. Without per-channel fusing, you'd lose all 16 outputs to a single fault — unacceptable in a production environment.
- Regulated 12VDC output across ±5% tolerance: Access control devices are sensitive to voltage sag. Regulation means your door controller still sees 12V nominal even during peak load draw or minor AC line droop, preventing lockups or false alarms triggered by voltage dip.
Deployment Considerations:
- Watch your total current budget: 10A sounds like a lot until you're running 12 door strikes at 500mA each plus a reader at 100mA per channel. Add margin for inrush current on solenoids — brief spikes when a lock energizes can be 2–3x steady-state draw. A properly fused supply handles it, but verify you're not asking it to exceed 10A sustained.
- Fuse replacement is routine but requires downtime on that channel. Keep a stock of replacement fuses on-site (get the rating from the datasheet or your integrator) — one blown fuse can ground a door for hours if spares aren't available.
- Terminal block wiring is user-friendly, but confirm your installer is labeling outputs and load-testing them before moving to production. Miswired polarity or reversal won't destroy the AL1012ULXPD16CB, but it will leave your door controllers dead.
The AL1012ULXPD16CB is the right pick for warehouses, office buildings, or retail chains rolling out a standard multi-door access control architecture without oversized power requirements. It keeps cost down and failure isolation up — exactly what systems integrators want in a foundation power platform.
