Altronix AL1012ACM220 Multi-Output 12VDC Power Supply
The Altronix AL1012ACM220 is a 220VAC input power supply designed to deliver distributed 12VDC power across eight independent fused relay outputs. This unit is purpose-built for security infrastructure where you need circuit-level control and isolation — each output is independently fused, so a fault in one zone won't cascade across the system. Maximum output capacity is 10A total across all eight channels, with integrated battery charging support for UPS functionality.
Key Features
- Eight Fused Relay Outputs: Each output has independent fusing, meaning a short or overcurrent on one channel won't trip or compromise the others. Critical when you're powering multiple access control readers, solenoids, or sensor networks where isolation matters. You avoid the single-point-of-failure trap that simpler linear supplies create.
- 220VAC Input Compatibility: Designed for international installations and regions where 220V/240V mains are standard. If your facility runs on 220VAC infrastructure, this eliminates the need for a step-down transformer, simplifying installation and reducing power loss.
- 12VDC Regulated Output at 10A Total: The 10A capacity must be shared across all eight outputs, so plan your load accordingly — a single high-current device (e.g., a heavy-duty electric strike) may consume 2–3A, leaving 7–8A for the remaining zones. Regulated output keeps voltage stable even as load fluctuates, protecting sensitive electronics.
- Integrated Battery Charging: Built-in battery backup conditioning allows you to connect lead-acid or sealed batteries for uninterruptible power during mains failure. This is essential for access control systems, emergency lighting circuits, or alarm panels that cannot tolerate blackouts.
- FAI Certification: Meets FAI (Fire Alarm Industry) approval standards, a requirement in many jurisdictions for fire alarm and emergency backup power applications. Verify local code requirements before installation.
- Lifetime Limited Warranty: Altronix backs this unit with a lifetime limited warranty, reflecting confidence in the design and component selection. Verify warranty coverage details with your vendor.
Typical Deployment Scenarios
The AL1012ACM220 fits well in multi-zone access control installations where you need independent circuit protection — think apartment complexes, office buildings, or warehouses with distributed reader zones. Each fused output can power one or more readers, door strikes, or exit device controllers without risk of crosstalk. The battery charging feature makes it suitable for emergency backup applications, including fire alarm annunciation, emergency exit locks, or critical security door control during power loss.
If you're running networked camera arrays with separate 12VDC PoE injectors or auxiliary lighting (IR illuminators, strobes), the AL1012ACM220 can serve as the backbone distribution point, provided your total load stays within the 10A envelope. For higher power demands, consider a larger-capacity unit in the Altronix line.
Integration & Compatibility
The AL1012ACM220 is a standalone power conditioner — it accepts 220VAC mains and outputs 12VDC. It connects to any 12VDC load with standard screw terminals. No software, no ONVIF, no IP connectivity. This simplicity is a strength: it works with any access control system or device that accepts 12VDC, and it will outlast software-dependent hardware by years. If you need networked power distribution with monitoring and remote control, explore smart PDUs or networked relay modules instead.
Considerations Before Purchase
Calculate your worst-case simultaneous load across all eight outputs. If door strikes (typically 1–3A each) and readers (0.2–0.5A each) will ever draw more than 10A at the same time, this unit will not support your installation — you'll need to either load-balance across multiple supplies or step up to a higher-capacity model. Also confirm that 220VAC mains are available at your installation site; North American standard is 110–120VAC, so this unit is best suited to international deployments or facilities with dual-voltage infrastructure.
