Altronix ALTV248UL 8-Output 24VAC Power Supply
The Altronix ALTV248UL is a wall-mounted AC-to-DC power supply engineered for distributed 24VAC power delivery in mid-scale security and access control deployments. Operating from standard 115VAC line input, this unit provisions eight independent output circuits, each capable of delivering up to 3.5A of regulated 24/28VAC power. The modular output architecture means you can assign each circuit to a separate device or subsystem without power-sharing constraints — a critical advantage when coordinating multiple independent loads like camera dome motors, access control strikes, auxiliary lighting, and intercoms.
For integrators planning multi-camera installations or warehouse automation sites, the ALTV248UL eliminates the complexity of sourcing and managing multiple single-output power supplies. Eight fused outputs provide individual circuit protection; if one load fails or shorts, the remaining seven circuits remain unaffected. UL Listed and CE certified, this unit meets North American and European electrical compliance requirements, reducing pre-installation verification overhead and supporting faster commissioning timelines.
Key Features
- Eight Independent 24/28VAC Outputs: Each circuit operates on its own protection and voltage regulation, eliminating cross-circuit voltage sag when one device draws peak current. Particularly useful in camera arrays where dome motors and pan-tilt mechanisms draw transient current spikes.
- 3.5A Maximum Output Current Per Circuit: Each output can sustain up to 3.5A, providing enough headroom to power multiple mid-sized loads per circuit without thermal stress — for example, a combination of IR illuminators and a solenoid strike on a single output line.
- Regulated Output Voltage: Maintains stable 24/28VAC across all eight outputs, critical for camera reliability and access control device consistency. Voltage sag or instability can degrade image quality in infrared cameras and cause intermittent solenoid chatter.
- Individual Fused Circuit Protection: Each output circuit is fused independently. A short on one line does not cascade to other outputs, allowing the rest of your surveillance or access control infrastructure to remain operational during troubleshooting and repair.
- Wall-Mount Enclosure Design: Compact footprint supports installation in electrical cabinets, telco closets, or server room racks. No floor space required, and proximity to powered devices reduces cable runs and voltage drop risk over long wire distances.
- UL Listed and CE Certified: Compliance with North American (UL) and European (CE) safety standards eliminates the need for custom electrical review and accelerates approval by facility engineering teams.
Integration and Deployment
The ALTV248UL integrates directly into surveillance infrastructure where centralized power distribution reduces installation labor and cable clutter. Typical deployments include remote head-end facilities powering multiple camera domes, distributed access control systems, and auxiliary security circuits in warehouse or retail environments. The eight independent outputs allow flexible circuit assignment: dedicate one to camera power, another to access control, a third to lighting, and so on. Because each output is individually protected and regulated, you avoid the voltage-sharing conflicts that arise when mixing high-inrush and low-draw devices on shared power supplies.
For power supply planning in larger installations, the ALTV248UL serves as a building block — multiple units can be deployed in parallel or distributed across different zones. When combined with proper cabling infrastructure, this approach simplifies troubleshooting and load balancing across the security system.
Frequently Asked Questions
Q: What is the input voltage requirement for the ALTV248UL?
A: The ALTV248UL operates from 115VAC line input. It converts this AC input to regulated 24/28VAC across its eight output circuits.
Q: Can I daisy-chain multiple ALTV248UL units to increase output capacity?
A: Yes. Multiple units can be deployed in parallel, with each powering separate device groups or zones. Ensure your 115VAC feeder circuit has sufficient capacity for the aggregate input draw.
Q: What does the 3.5A maximum output per circuit mean in practical terms?
A: Each of the eight circuits can supply up to 3.5A continuously. For example, a typical PTZ camera dome motor draws 0.5–1.5A, so a single output can safely power one dome plus auxiliary loads (IR illuminator, strike solenoid) without exceeding the rated current.
Q: Are the outputs individually protected if a device shorts?
A: Yes. Each output is fused independently. A short on one circuit will trip only that circuit's fuse, leaving the other seven outputs operational.
Q: What warranty does the ALTV248UL include?
A: The unit includes a Lifetime Limited Warranty covering manufacturing defects.
Q: Can the ALTV248UL be installed in a wall cabinet or electrical enclosure?
A: Yes. The wall-mount form factor is optimized for cabinet and telco closet installation. Ensure adequate ventilation and clearance around the unit for proper heat dissipation.

The Altronix ALTV248UL is a workhorse for any mid-scale security or access control build-out where you need stable, independent power to multiple device types. Eight fused circuits at 3.5A per output gives you real flexibility — you're not forced to choose between powering camera domes or solenoid strikes; you can do both without voltage sag or cross-circuit ripple.
Technical Highlights:
- 8 Independent Circuits @ 3.5A Each: Unlike single-output supplies, this architecture means a peak-current draw from one device (dome motor inrush) doesn't degrade voltage delivery to the others. Real benefit on camera arrays or access control systems with multiple simultaneous loads.
- Individual Fusing Per Circuit: Short on one output trips only that circuit's fuse. The other seven keep running — critical for uptime in retail or warehouse deployments where you can't afford a total power loss.
- 115VAC Input to Regulated 24/28VAC Output: Stable, regulated output ensures consistent solenoid actuation times and camera dome motor speed. Unstable supplies degrade reliability and cause intermittent field troubleshooting calls.
- UL Listed and CE Certified: Simplifies compliance review and shortens commissioning timelines; no custom electrical engineering required for facility sign-off.
Deployment Considerations:
- Load Balancing: Eight circuits doesn't mean unlimited power. Calculate total inrush and sustained current draw across all loads before deployment. If all eight outputs are maxed at 3.5A simultaneously, you're pulling roughly 28A from the 115VAC input — ensure your facility feeder supports this peak draw.
- Thermal Headroom: Wall-mount enclosures can run warm under heavy, sustained load. Install in a location with adequate ventilation; don't box it into a closed cabinet without airflow.
- Cable Runs: 24VAC voltage drop over long distances is real. Keep output wiring distances reasonable (under 100–150 feet for typical solenoids and camera domes); longer runs may require heavier gauge wire or a secondary supply closer to the load.
Deploy the ALTV248UL in access control head-ends, remote camera power hubs, or warehouse lighting and automation distribution points. It's genuinely useful when you have five to eight separate 24VAC loads in one location and want single-point power management with granular circuit protection.
