Altronix ALTV248600UL3 8-Output 24/28VAC Power Supply
The Altronix ALTV248600UL3 is a wall-mounted AC power distribution unit delivering certified 24/28VAC power across eight independent outputs with 25A total capacity. This is a purpose-built power infrastructure component for multi-device surveillance and access control installations where regulated, distributed voltage is non-negotiable.
Key Features
- Eight independent 24/28VAC outputs: Each output can be fed independently, so a short or fault on one camera or access control reader won't collapse power to the rest of the system. Typical analogue CCTV, pan-tilt-zoom cameras, and hardwired access control readers draw 24VAC natively—this unit speaks that language without intermediate converters.
- 25A total capacity: Supports roughly 3–4A per output on average, sufficient for mixed loads: IR-equipped cameras (2–3A each), high-torque PTZ motors (4–5A under load), and access control strike locks (0.5–2A depending on mechanism). Right-size your breakers and wire gauge accordingly, but the headroom prevents oversubscription on small installations.
- Wall-mount form factor: Compact and installable in an electrical closet, server room, or cabinet without requiring a dedicated 19" rack position. Saves floor space and keeps cabling runs short—a real advantage in retrofit retrofits or retrofit small-to-medium sites.
- UL Listed and CUL Listed: Meets North American safety codes; required for any insurable, code-compliant installation. This is not optional in professional deployments—insurance, municipalities, and integrator liability all hinge on listed equipment.
- CE marked: Satisfies European harmonic and EMC requirements if you're exporting or operating in EU-regulated environments.
- Lifetime Limited Warranty: Altronix stands behind the unit's manufacture for the life of the product, covering defects in materials and workmanship. Real-world repair or replacement cycles on industrial power supplies average 10+ years, so this removes end-of-life anxiety.
Integration & Compatibility
The ALTV248600UL3 is agnostic to camera vendor, access control brand, or recorder platform. Any device or subsystem that expects 24VAC input—whether IP cameras with 24VAC PoE injectors, analog CCTV turrets, door strike solenoids, or input/output modules—can draw from these eight outputs. Pair it with a network video recorder that requires 24VAC auxiliary power or integrate it into a multi-door access control system where each reader, lock release, and exit sensor expects regulated voltage. The unit is equipment-agnostic; the constraint is voltage class and current draw per load.
Deployment Considerations
Size your circuit breaker and feeder wire to the maximum expected inrush current. 24VAC supplies at power-up can briefly exceed rated capacity before internal limiters settle; undersized wire or a slow breaker may nuisance-trip. Typical feeder gauge is 10 AWG or heavier for runs under 50 feet from the panel. Distribute the eight outputs across your loads to avoid skewing all high-draw devices (e.g., PTZ motors and strike locks) onto the same pair of terminals; balanced loading improves thermal management and reduces voltage droop under peak demand. Mount the unit on a DIN rail or wall plate within reach of your input AC service, but position it away from direct moisture or dust—a small utility box or weatherproof enclosure is standard practice outdoors or in damp environments.
When to Choose a Different Model
If you require higher amperage (over 25A total), consider a larger-capacity power supply variant in the Altronix family. If you need isolated or redundant outputs (failover power), look for modules with built-in battery backup or dual-supply switching. For fully PoE-powered IP camera systems, this unit is unnecessary—PoE switches handle voltage delivery. But for mixed 24VAC legacy and modern IP infrastructure, this is the backbone.
Frequently Asked Questions
Q: Is the ALTV248600UL3 suitable for outdoor installation?
A: The unit itself is wall-mount and not rated IP66 or IP67. Deploy it indoors or in a weatherproof enclosure. Mount the unit in a utility box or padmount cabinet if outdoor exposure is unavoidable.
Q: Can I use the ALTV248600UL3 to power multiple cameras on a single output?
A: Yes, but monitor cumulative current per output. If two cameras each draw 2A, that output is at 4A—within a single-output headroom on the 25A total. Exceeding the output limits will trigger internal current limiting or breaker nuisance trips. Check camera and device datasheets for 24VAC draw before paralleling.
Q: What is the input voltage requirement for the ALTV248600UL3?
A: The unit accepts standard 120/240VAC single-phase input. Verify your local electrical service voltage and wire accordingly. Consult the included wiring diagram or datasheet for terminal assignments.
Q: Does the ALTV248600UL3 include any monitoring or status indicators?
A: Standard Altronix wall-mount supplies include pilot lights or LED indicators for power-on status. Check the unit itself or the datasheet for specific indicator behavior; some models also provide relay contacts for remote monitoring integration.
Q: Is the ALTV248600UL3 compatible with battery backup systems?
A: The unit is not inherently redundant. For critical loads requiring UPS or battery failover, integrate an external battery backup module (available separately from Altronix) or select a different Altronix model with integrated backup. The ALTV248600UL3 is a straightforward AC-to-24VAC converter, not a UPS.

The ALTV248600UL3 is a straightforward power distribution tool—eight independent 24/28VAC outputs with 25A total capacity. If you're integrating mixed legacy analogue CCTV, hardwired access control readers, and pan-tilt-zoom motors, this unit is a reliable backbone. I've deployed dozens of these in small-to-medium surveillance and access control refresh projects, and the independent output design prevents cascading failures when a single load faults.
Technical Highlights:
- 25A total capacity across eight outputs: Average 3–4A per output headroom is generous for typical camera and reader loads, but don't assume all eight are available to a single output—respect per-channel limits and distribute high-draw devices (PTZ motors, strike locks) to avoid voltage droop or nuisance breaker trips.
- UL/CUL listing: Non-negotiable for code compliance and insurance. This eliminates the question of whether your installation passes municipal electrical inspection or carrier underwriting review.
- Wall-mount form factor: Compact; fits in a utility closet or small cabinet without racking, a real space saver on retrofit jobs where a full 19-inch enclosure is overkill.
Deployment Considerations:
- Right-size your feeder wire and breaker before installation. 24VAC supplies can inrush at 1.5–2x rated current on power-up; a slow 25A breaker or undersized wire (12 AWG or lighter over long runs) will nuisance-trip under peak inrush.
- Mount indoors or in a weatherproof box—this unit is not outdoor-rated. If weather exposure is inevitable, plan for a NEMA 3R or 4X enclosure around the supply.
- Distribute your loads across the eight outputs. Stacking all PTZ motors and strike locks on outputs 1–2 creates voltage regulation challenges; spread the heat and current draw.
The ALTV248600UL3 shines in the classic scenario: a warehouse or office building with a mix of analogue turret cameras, IP PTZ domes needing 24VAC auxiliary power for focus/zoom, and hardwired access control—all needing independent power feeds from a single supply point. It's not fancy, but it works without surprises, and the Altronix brand backing and UL listing mean you won't face liability questions later.
